Successful Grinding Production Line

Grinding Production Line

Grinding plant consists of mainframe, speed reducer, powder separator, blower, bag filter, pipes, cyclone, motor, etc. The peripheral equipments are jaw crusher, bucket elevator, feeder, hopper, electric control panel, etc. Grinding mill can grind all kinds of non-flammable and non-explosive minerals with Moh’s hardness lower than 9 and humidity less than 6%，and is widely used in metallurgy, manufacture of building materials, chemical industry, mining industry, etc.

Working principle

Large materials are crushed by pe jaw  crusher to the needed sizes firstly. Then the materials are elevated to storage hopper by bucket elevator, Thirdly, the materials are fed into the grinding chamber for grinding by vibrating feeder equably and continuously. The powder after grinding goes upwards together with the airflow, after separated by powder separator, those which can meet the fineness requirement enters into the cyclone powder collector through pipe together with the airflow, and then discharged from the discharge valve as final products. 

The airflow is sucked into centrifugal blower through wind recycling pipe at the upper part of cyclone powder collector. The mainframe is driven by the speed reducer through the central axis in the mill. The quincunx stand connected with the upper part of central axis, at the quincunx stand, rollers are set and by which the vibrating pivot formed. Below the quincunx stand and rollers there is shovel system. Materials are fed into the space between rollers and shovels when they are turning, and then be grinded by the pressure produced when rollers are turning, thus powder is made。

7 Points Help You To Choose A Jaw Crusher

Jaw crusher is mainly used for crushing various ores and large materials with compression strength not more than 320Mpa into medium-sized grains. PE jaw crusher is used as primary crusher and secondary crusher since they can effectively achieve coarsely crushing. it can process large stones with large capacity primarily and thus become the first choice for primary crushing. But how to choose a good jaw crusher,there are seven points may can help you.

Firstly: the first is to see into the grain-size of the crusher, and partical size, the material particle size, the greater the product particle size, the more coarse, into the material particle size is smaller, the greater the product particle size. So, according to own actual situation to choose different models of jaw crusher.

Second: want to see the quality of lining board of jaw crusher, jaw crusher method of choose and buy needs to consider three factors: production, liner wear resistance and power consumption of the equipment. In general, the biggest feed particle size depends on the equipment, the change of particle size, feed particle size distribution of material wear resistance and hardness of the material.

Third: generally, the length of the lining board of jaw crusher and its power consumption is proportional to the size of the, the longer the lining board, the higher the power consumption, in general, soft material choose long lining board, hard material choose short lining board. On material distribution, fine material choose short liner, coarse material choose long strap.

Fourth: the bigger of the two materials will affect the moisture content of material by volume, material moisture is no more than 5% commonly, in terms of the use of power, the standard models of jaw crusher should be around 80%, short head type jaw crusher should be around 85%.

Fifth: jaw crusher feed particle size, in general, less than silent on the edge of the material discharging mouth cannot exceed 10%, once more than, can lead to equipment power consumption rising, product particle size becomes a flake.

Sixth: jaw crusher during the work, make sure the feeding must be uniform, no segregation, otherwise, to cause a decline in production capacity, product size is not uniform, the action of spring too frequently, power consumption will also rise. There is a little special attention is, must install iron removal equipment, if there is excessive iron products frequently appear in the bin, it may cause broken shaft.

Seven: jaw crusher of choose and buy method is very simple, first of all, jaw crusher, working environment is poor, dust will be big, plus some units in the process of use do not pay attention to the maintenance of equipment, often can appear some problems, so it is necessary to equipment maintenance work. It is important to note.

Features Of The PE Jaw Crusher

PE jaw crusher overview

 Jaw crusher in mining, building materials, construction and other departments are mainly used as coarse crusher and crusher. According to the feed Mouth width size is divided into large, medium and small three, inlet width is greater than 600 mm for large machines, feed port in 300-600 - mm width for medium-sized machine, feeding mouth width is less than 300 mm for the minicomputer. Jaw crusher structure is simple, easy manufacturing, reliable work, convenient use and maintenance.

Work part of the jaw crusher is two pieces of jaw plate, one is the fixed jaw plate (jaw), vertical (or the upper slightly extraversion) fixed in front of the body wall, the other is movable jaw board (dynamic jaw), tilt, and fixed jaw plate form on the small crushing cavity cavity (work). Activity fixed jaw jaw slabs with periodic reciprocating motion, sometimes separately, sometimes near. Separately, material into the crushing cavity, finished products from the lower discharge; Approached, the materials are squeezed between two pieces of jaw plate, bending and fracturing effect and broken.

How to realize the smooth transition effect

Transition of CSS allows CSS attribute values in a certain time interval smoothly transition. This effect can be click on mouse click, focus, or for any change in the elements of trigger, and tactful to animation effects change the CSS property values.

Do you know this web page http://www.grindingmill.org/ that the effect of several ICONS at the upper right is how to implement? Here we step by step from its most grammar and attribute values used to learn the details of the transition.

Grammar:

 transition ： [<'transition-property'> || <'transition-duration'> || <'transition-timing-function'> || <'transition-delay'> [, [<'transition-property'> || <'transition-duration'> || <'transition-timing-function'> || <'transition-delay'>]]*

Transition mainly contains four attribute values: perform the transform properties: the transition - property, transform the continuation of time: the transition - duration, the extended period of time, change the rate of change the transition - timing - function, transform to delay the transition time - delay. Below to see the four attribute values, respectively.

一、transition-property:

transition-property ： none | all | [ <IDENT> ] [ ',' <IDENT> ]*

二、transition-duration:

transition-duration ： <time> [, <time>]*

三、transition-timing-function:

 transition-timing-function ： ease | linear | ease-in | ease-out | ease-in-out | cubic-bezier(<number>, <number>, <number>, <number>) [, ease | linear | ease-in | ease-out | ease-in-out | cubic-bezier(<number>, <number>, <number>, <number>)]*

四、transition-delay:

transition-delay ： <time> [, <time>]*

Sometimes we will not only change the effect of a CSS properties, but to change two or more CSS properties of the transition effect, so we just put several transition statement strung together, separated by a comma (", "), then each may have different duration and the time rate of transformation methods. But need to note: the transition to delay and the transition to the value of the duration time, so want to distinguish them in the position of ligatures, general browser will be determined according to the order, the first time can be resolved as  values for the transition - duration for the second transition - delay. Such as:

a {

    -moz-transition: background 0.5s ease-in,color 0.3s ease-out;

    -webkit-transition: background 0.5s ease-in,color 0.3s ease-out;

    -o-transition: background 0.5s ease-in,color 0.3s ease-out;

    transition: background 0.5s ease-in,color 0.3s ease-out;

  }

If you want to perform all the transition effect the properties of the elements, so we can also use all attribute values to the operation, at the moment they Shared the same duration as well as the rate of transformation, such as:

a {

    -moz-transition: all 0.5s ease-in;

    -webkit-transition: all 0.5s ease-in;

    -o-transition: all 0.5s ease-in;

    transition: all 0.5s ease-in;

  }

Corresponding to a sample code:

p {

  -webkit-transition: all .5s ease-in-out 1s;

  -o-transition: all .5s ease-in-out 1s;

  -moz-transition: all .5s ease-in-out 1s;

  transition: all .5s ease-in-out 1s;

}

Now you have learned it ?

Impact Crusher Type

Impact crusher can be divided into single rotor and double rotor according to the structural characteristics .

The single rotor structure is simple, suitable for medium and small factories. And can be divided into the lower part of casing setting even grate plate and without even grate pull two categories. Lower set even grate plate impact crusher. Can control the finished size, reduce the large particles, finished product size is even, this is because the tiny particles through the grate seam after discharge, continue to be large particles remained in grate surface plate hammer blow and grinding, until discharged after crushing. 

Words of the suspension point of grate plate can move horizontally, to adapt to the working condition of all kinds of broken. Adjust screw laurel grate plate bottom have to adjust the grate plate and rotor Angle between t compensation caused by wear plate hammer and grate plate after clearance.

Double rotor type product rotor type impact crusher according to the rotor rotation direction can be divided into three categories:

1.two rotor rotation direction, the equivalent of two single rotor impact crusher series use. Broken than large, finished product granularity and the productivity is high, but the energy consumption is large, can also be crushed, crusher, finely. Simplify the production process.

2. the two rotor reverse rotation, equivalent to two single rotor pf imapct crusher used in parallel, productivity is high. Can break larger piece of material. Only for crushed and broken in.

3. the two rotor is not in the same horizontal plane relative to rotation, can use two rotor relative to throw in material from the phase of the impact and breakage. Broken than large, metal wear less.

Increase the number of the crushing cavity, can strengthen the selective crushing, broken ratio increases. So, by adding the crushing cavity, can reduce the rotor speed and usually need high speed to reach the effect of broken.

Choosing the best crusher means you will have less bothers during the producing process. Here are some advices of choosing and purchasing the secondary crusher:

The secondary crusher mainly includes PEW European technology jaw crusher, impact crusher and cone crusher. They often follow the coarse crusher-jaw crusher. The discharge opening range is 10-80mm. Their differences are as following:

1. PEW jaw crusher has the similar working principle of cone crusher, both of them adopt the squeezing measure. So the sand shape is not enough good, you can choose the two crushers if your demand is not restrict.

2. Generally, the PEW European type jaw crusher has a small capacity; it needs several crushers working together for getting the demand. Impact crusher and cone crusher have many specifications; they can adapt all sorts of demand.

3. Impact crusher adopts the working principle of rock on rock and rock on iron, the rotor shoots materials which makes them break on the impact plate and break them mutually. So the impact crusher could be as shaping machine for stone.

4. Working principles distinctiveness makes the spare parts service life differences. With the same operation load, impact crusher’s spare parts service life is shorter.

VariousTypes Of Crushers

The commonly used crushers including jaw crusher, cone crusher,impact crusher,gyratory crusher and so on.

Jaw crusher

A jaw crusher uses compressive force for breaking of particle. This mechanical pressure is achieved by the two jaws of the crusher of which one is fixed while the other reciprocates. A jaw or toggle crusher consists of a set of vertical jaws, one jaw is kept stationary and is called as fixed jaw while the other jaw, called as swing jaw, moves back and forth relative to it, by a cam or pitman mechanism, acting like a class II lever or a nutcracker. The volume or cavity between the two jaws is called as the crushing chamber. The movement of the swing jaw can be quite small, since complete crushing is not performed in one stroke. The inertia required to crush the material is provided by a weighted flywheel that moves a shaft creating an eccentric motion that causes the closing of the gap.

Jaw crushers are heavy duty machines and hence need to be robustly constructed. The outer frame is generally made of cast iron or steel. The jaws themselves are usually constructed from cast steel. They are fitted with replaceable liners which are made of manganese steel, or Ni-hard (a Ni-Cr alloyed cast iron). Pew Jaw crushers are usually constructed in sections to ease the process transportation if they are to be taken underground for carrying out the operations.

Jaw crushers are classified on the basis of the position of the pivoting of the swing jaw

1. Blake crusher-the swing jaw is fixed at the upper position
2. Dodge crusher-the swing jaw is fixed at the lower position
3. Universal crusher-the swing jaw is fixed at an intermediate position

The Blake crusher was patented by Eli Whitney Blake in 1858. The Blake type jaw crusher has a fixed feed area and a variable discharge area. Blake crushers are of two types- single toggle and double toggle jaw crushers.

In the single toggle jaw crushers, the swing jaw is suspended on the eccentric shaft which leads to a much more compact design than that of the double toggle jaw crusher. The swing jaw, suspended on the eccentric, undergoes two types of motion- swing motion towards the fixed jaw due to the action of toggle plate and vertical movement due the rotation of the eccentric. These both motions, when combined, lead to an elliptical jaw motion. This motion is useful as it assists in pushing the particles through the crushing chamber. This phenomena leads to higher capacity of the single toggle jaw crushers but it also results in higher wear of the crushing jaws. These type of jaw crushers are preferred for the crushing of softer particles.

In the double toggle jaw crushers, the oscillating motion of the swing jaw is caused by the vertical motion of the pitman. The pitman moves up and down. The swing jaw closes, i.e., it moves towards the fixed jaw when the pitman moves upward and opens during the downward motion of the pitman. This type is commonly used in mines due to its ability to crush tough and abrasive materials.

In the Dodge type jaw crushers, the jaws are farther apart at the top than at the bottom, forming a tapered chute so that the material is crushed progressively smaller and smaller as it travels downward until it is small enough to escape from the bottom opening. The Dodge jaw crusher has a variable feed area and a fixed discharge area which leads to choking of the crusher and hence is used only for laboratory purposes and not for heavy duty operations.

Gyratory crusher

A gyratory crusher is similar in basic concept to a jaw crusher, consisting of a concave surface and a conical head; both surfaces are typically lined with manganese steel surfaces. The inner cone has a slight circular movement, but does not rotate; the movement is generated by an eccentric arrangement. As with the jaw crusher, material travels downward between the two surfaces being progressively crushed until it is small enough to fall out through the gap between the two surfaces.

A gyratory crusher is one of the main types of primary crushers in a mine or ore processing plant. Gyratory crushers are designated in size either by the gape and mantle diameter or by the size of the receiving opening. Gyratory crushers can be used for primary or secondary crushing. The crushing action is caused by the closing of the gap between the mantle line (movable) mounted on the central vertical spindle and the concave liners (fixed) mounted on the main frame of the crusher. The gap is opened and closed by an eccentric on the bottom of the spindle that causes the central vertical spindle to gyrate. The vertical spindle is free to rotate around its own axis. The crusher illustrated is a short-shaft suspended spindle type, meaning that the main shaft is suspended at the top and that the eccentric is mounted above the gear. The short-shaft design has superseded the long-shaft design in which the eccentric is mounted below the gear.

Cone crusher

A cone crusher is similar in operation to a gyratory crusher, with less steepness in the crushing chamber and more of a parallel zone between crushing zones. A cone crusher breaks rock by squeezing the rock between an eccentrically gyrating spindle, which is covered by a wear resistant mantle, and the enclosing concave hopper, covered by a manganese concave or a bowl liner. As rock enters the top of the cone crusher, it becomes wedged and squeezed between the mantle and the bowl liner or concave. Large pieces of ore are broken once, and then fall to a lower position (because they are now smaller) where they are broken again. This process continues until the pieces are small enough to fall through the narrow opening at the bottom of the crusher.

A cone crusher is suitable for crushing a variety of mid-hard and above mid-hard ores and rocks. It has the advantage of reliable construction, high productivity, easy adjustment and lower operational costs. The spring release system of a cone crusher acts an overload protection that allows tramp to pass through the crushing chamber without damage to the crusher.

Impact crusher

Impact crushers involve the use of impact rather than pressure to crush material. The material is contained within a cage, with openings on the bottom, end, or side of the desired size to allow pulverized material to escape. There are two types of impact crushers: horizontal shaft impactor and vertical shaft impactor.

Crusher Background History

A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, or rock dust.

In industry, crushers are machines which use a metal surface to break or compress materials into small fractional chunks or denser masses. Throughout most of industrial history, the greater part of crushing and mining part of the process occurred under muscle power as the application of force concentrated in the tip of the miners pick or sledge hammer driven drill bit. Before explosives came into widespread use in bulk mining in the mid-nineteenth century, most initial ore crushing and sizing was by hand and hammers at the mine or by water powered trip hammers in the small charcoal fired smithies and iron works typical of the Renaissance through the early-to-middleindustrial revolution. It was only after explosives, and later early powerful steam shovels produced large chunks of materials, chunks originally reduced by hammering in the mine before being loaded into sacks for a trip to the surface, chunks that were eventually also to lead to rails and mine railways transporting bulk aggregations that post-mine face crushing became widely necessary. The earliest of these were in the foundries, but as coal took hold the larger operations became the coal breakers that fueled industrial growth from the first decade of the 1600s to the replacement of breakers in the 1970s through the fuel needs of the present day. The gradual coming of that era and displacement of the cottage industry based economies was itself accelerated first by the utility of wrought and cast iron as a desired materials giving impetus to larger operations, then in the late-sixteenth century by the increasing scarcity of wood lands for charcoal production to make the newfangled window glass^[2] material that had become—along with the chimney— 'all the rage'  among the growing middle-class and affluence of the sixteenth-and-seventeenth centuries;and as always, the charcoal needed to smelt metals, especially to produce ever larger amounts of brass and bronze,^[3] pig iron, cast iron and wrought iron demanded by the new consumer classes. Other metallurgical developments such as silver and gold mining mirrored the practices and developments of the bulk material handling methods and technologies feeding the burgeoning appetite for more and more iron and glass, both of which were rare in personal possessions until the 1700s.

Things only became worse when the English figured out how to cast the more economical iron cannons (1547), following on their feat of becoming the armorers of the European continent's powers by having been leading producers brass and bronze guns, and eventually by various acts of Parliament, gradually banned or restricted the further cutting of trees for charcoal in larger and larger regions in the United Kingdom.In 1611, a consortium lead by courtier Edward Zouch was granted a patent for the reverberatory furnace, a furnace using coal, not precious national timber reserves, which was immediately employed in glass making. An early politically connected and wealthy Robber Baron figure Sir Robert Mansell bought his way into the fledgling furnace company wrested control of it, and by 1615 managed to have James I issued a proclamation forbidding the use of wood to produce glass, giving his families extensive coal holdings a monopoly on both source and means of production for nearly half-a-century. Abraham Darby a century later relocated to Bristol where he had established a building brass and bronze industry by importing Dutch workers and using them to raid Dutch techniques. Both materials were considered superior to iron for cannon, and machines as they were better understood. But Darby would change the world in several key ways.

There are many types of crushers,such as pew jaw crusher, grratory crusher,cone crusher,impact crusher.

Mining operations use crushers, commonly classified by the degree to which they fragment the starting material, with primary and secondary crushers handling coarse materials, and tertiary and quaternary crushers reducing ore particles to finer gradations. Each crusher is designed to work with a certain maximum size of raw material, and often delivers its output to a screening machine which sorts and directs the product for further processing. Typically, crushing stages are followed by milling stages if the materials need to be further reduced. 

Additionally rockbreakers are typically located next to a crusher to reduce oversize material too large for a crusher. Crushers are used to reduce particle size enough so that the material can be processed into finer particles in a grinder. A typical processing line at a mine might consist of a crusher followed by a SAG mill followed by a ball mill. In this context, the SAG mill and ball mill are considered grinders rather than crushers.

In operation, the raw material (of various sizes) is usually delivered to the primary crusher's hopper by dump trucks, excavators or wheeled front-end loaders. A feeder device such as an apron feeder, conveyor or vibrating grid controls the rate at which this material enters the crusher, and often contains a preliminary screening device which allows smaller material to bypass the crusher itself, thus improving efficiency. Primary crushing reduces the large pieces to a size which can be handled by the downstream machinery.

Some crushers are mobile and can crush rocks as large as 60 inches. Primarily used in-pit at the mine face these units are able to move with the large infeed machines (mainly shovels) to increase the tonnage produced. In a mobile road operation, these crushed rocks are directly combined with concrete and asphaltwhich are then deposited on to a road surface. This removes the need for hauling over-sized material to a stationary crusher and then back to the road surface.
