impact crusher and cone crusher have different use

Impact crusher and cone crusher are broken equipment common, they have what different? The production of a full set of crusher machine for many years, knows the secret, then, whether you are a veteran or new industry, or have a look this article, I know more than the product description, a better understanding of the.
Impact crusher , the biggest characteristic is: big crushing ratio. The product particle type! This impact crusher  should be used stone dozen stone for its technology, the repeated impact between materials, to minimize the loss of machinery and equipment, but this principle also determines the counter limitation broken: for crushing hard rock not what advantage.
In contrast, cone crusher is suitable for crushing hard rock, from the principle of speaking, the changes in the size of the gap between the cone crusher is a cone with two head to head the to crushing and release of stone (this is the image of the pressing process, the crushing effect is good). Of course, do such heavy work should be done well enough safety measures, so as to avoid damage to the clerk go getters.
Safety device that usually have a mechanical spring device and a hydraulic spring device two, but the current hydraulic cone crusher is developing rapidly, has become the main force, the machines now are mainly produce hydraulic cone breaker, the cone crusher according to the discharge port adjusting different and main shaft installation can be divided into fixed and spindle the spindle movable type two kinds, the main shaft fixing hydraulic cone crusher outlet is adjusted by rotating the fixed cone screw fixed cone rolling mortar wall moves up and down to adjust the discharge port, the spindle is short and thick, fixed in the frame, large carrying capacity.
The following insurance device principle: in the crushing process, crushing force is pulsating, in the face of can not be broken, insurance device will open the broken gap, make excellent material through, elected by the subsequent processing equipment.
The nine sons of the dragon are different, the crusher is also so, as much as possible to understand each model's characteristics, is conducive to the use of more effective crushing equipment to complete production tasks.

cement mixer machine used in the cement making plant

Cement is a hydraulic powder material, which reacts with water to produce strength-bearing lattices. The mixture of aggregates, cement and water is concrete. The strength and durability of concrete makes it one of the most useful materials developed by man. The chemistry and mineralogy of cement is complex. In simple terms, cement is a manmade mineral structure created at high temperatures, mainly comprising lime, Silica and oxides of aluminium and iron . People has pay more and more attention to the cement making plant in recent years.
The cement making process can be divided; first "clinker" is made at temperatures of 1400 oC. Then the clinker is milled with other minerals to produce the powder we know as cement.
The raw materials, used to produce clinker includes some naturally occurring minerals and some materials available as waste streams from other industries. The most common combination of ingredients is limestone (for calcium) coupled with much smaller quantities of clay, shale and sand (as a source of silica, aluminium and iron) in the cement clinker grinding plant . Other "alternative" raw materials such as mill scale, fly ash and slag are brought in from other industries. Plants generally rely on nearby quarries for limestone to minimise transport.
Rock blasted from the quarry face is transported to the primary crusher where large "run of mine" rocks are broken into pieces of approximately 100mm. Generally the other raw materials do not require crushing. The raw materials are then proportioned to the correct chemical balance and milled together to a fine powder, "rawmeal. To ensure high quality of cement, the chemistry of the raw materials and rawmeal is very carefully controlled. Kiln exhaust gases are used in the raw mill to dry the raw materials used the cement mixer machine. In some gases with wet materials, additional heat sources are required for drying.
Materials are also homogenised to ensure consistency of product quality.
Preheater:
Rawmeal is the feed material for the high temperature process in the kiln system. "Preheating" is the first part of this system. A pre-heater is a series of vertical cyclones. As the raw meal is passed down through these cyclones it comes into contact with the swirling hot kiln exhaust gases moving in the opposite direction and as a result heat is transferred from the gas to material. This pre-heats the material before it enters the kiln so that the necessary chemical reactions will occur more quickly and efficiently. By retaining energy from the exhaust gases, energy is saved. Depending on the raw material moisture, a kiln may have 3 to 6 stages of cyclones with increasing heat recovery with each extra stage.
The calciner is a combustion chamber at the bottom of the preheater above the kiln back-end. Up to 65% of the total energy needs of the kiln system can be supplied to the calciner. Calciners allow for shorter rotary kilns and for the use of lower grade alternative fuels. Calcination is the decomposition of CaCO3 to CaO, which releases CO2. These process emissions comprise 60% of the total emission from a cement kiln. The combustion of the fuel generates the rest.

jaw crusher open up new roads for the road highway


To start up a stone factory need investment is not a small number, from the beginning of the land purchasing and production equipment, transportation equipment, procurement, these are the need to invest a lot of money. If there is not enough money to support, a stone factory pre hard to operate. If the production benefit is good, having a broad, short term funds can be recovered, turnover is rapid, calcium carbonate crusher plant factory operations will be very smooth. Investors in the investment before should first do market research, think good product sales.

Choose a quarry products also need to pay more attention to the:

1 quality assurance, customer service and thoughtful
Machinery market now has a lot of fish in troubled waters of informal enterprises, shoddy, user a little inattentive gullible, if the quality of the equipment can not guarantee what to talk about future production work, and after sale service is very necessary, if damage to the equipment is not timely repair will delay the production schedule, resulting in direct economic loss. Customer service is the powerful guarantee for the normal operation of the machine later.

The 2 measure, for the best

Stone grinding machine many models, a variety of processing methods, production, yield, fineness is different, so the user to buy the equipment must be clear stone grinding machine what type you want. such as pe jaw crusher, impact crusher or cone crusher. There is a need to yield large, there is a need to fineness, which requires a completely equipped with different types of grinding equipment, once the model is wrong, it will bring great influence to the future production.

3 money is king, goods than three home

The purchase of machinery and equipment are most concerned about is the price, we do not recommend the user to measure an equipment with the price of the good and the bad, good equipment to buy it should buy quality assured, but the stone grinding machine manufacturer so much, in the case of the same quality we recommend that users by contrast, choose one a quality assurance also fair price of the manufacturers to buy. Zenith has many used stone crusher in south Africa. The general models, quality equipment from different manufacturers is not the price difference, if there is a sales company selling price is very cheap, it would have to be careful.

The importance of ball mill in the cement clinker processing plant

The ball mill is a key facility for re-crushing after the materials are primarily crushed. It has been widely used in many production industries such as cement, silicate, new type building materials, fireproofing, chemical fertilizer, black and non-ferrous metal, and glass ceramics. It's widely used in the cement clinker processing plant and it can realize dry type or wet type grinding for all kinds of ores and other grindable materials .
Ball Mill is mainly used to grind materials in mineral, cement, refractory, chemical industry, etc. Ball Mill has dry and wet ways. When wet Ball Mill works, certain water and other liquid will be added into materials to increase flowability of materials, so the capacity is increased. When dry Ball Mill works, capacity is affected because material flowability is reduced, so absorbing wind device is needed on the outlet of Ball Mill, and then negative pressure is formed in the Ball Mill to increase flowability of material, so the capacity is increased.
No matter in sand production line or in ore mining plant, zenith is quite popular in these fields. In particular, cement is the raw material in pozzolana cement production line. Among various ball mills, zenith ball mill becomes the one of the primary machines for cement plant and ore beneficiation plant.
