The growth in demand for grinding mills

The growth in demand for size reduction equipment is not surprising considering the number of industrial applications that require size reduction operations. There is no dearth for grinding mills in South Africa for sale in the market since raw materials often occur in sizes that are too large to be used in production processes which requires their size to be reduced accordingly.

However, no single grinding machine can perform all the processes required in grinding particularly in instances when the material is either too hard or brittle. Size reduction in food processing can be divided into two categories: solid and liquid. For solid materials the operations are called grinding and cutting while for liquid materials, the operations are emulsification or atomization.

The process of grinding and cutting

One of the most extensive applications of the grinding machines in the food industry is the milling of grains to make flour however, grinding mills for sale in Zimbabwe that can also be used for other products like grinding corn for corn starch, grinding of sugar and milling of dried fruits and vegetables. Cutting is an operation used to break down large sizes of food into smaller pieces for further processing particularly in meat and poultry processing. Cutting machinery is relatively simple as it consists of rotating knives in various arrangements. One issue however with cutting machinery is how to keep the knives sharp so that they can cut and not tear.

Some manufacturing processes benefit from a combination of complimentary small scale stone grinding equipment technologies. These two-way processes maximize the efficiency of the size reduction equipment. Grinding equipment can be divided as to crushers and grinders. When a uniform particle is crushed, the size of the particle will vary a great deal and as the grinding continues the particles will turn from relatively coarse to fine and even to dust if required.

 working principle

Impact crusher is an high-efficiency crushing equipment. It uses plate hammer on the rapidly rotating rotor to generate high-speed impact to crush the materials in the crushing cavity, and casts the crushed materials along tangential direction to impact plate at the other end of the crushing cavity. The materials are crushed again, and then, they return to the plate hammer to undergo the process above repeatedly.

The materials are bumping with each other when being sent between the plate hammer and the impact plate. The materials become cracked, loose and then comminuted by knocking by the plate hammer, impact with impact plate and bump between materials. The materials with grain size smaller than the gap between impact plate and plate hammer will be discharged.

Cement Processing Plant

There are 27 types of common cement which can be grouped into 5 general categories and 3 strength classes: ordinary, high and very high.  In addition, some special cements exist like sulphate resisting cement, low heat cement and calcium aluminate cement.

Cement is a fine powder which sets after a few hours when mixed with water, and then hardens in a few days into a solid, strong material. Cement is mainly used to bind fine sand and coarse aggregates together in concrete.  Cement is a hydraulic binder, i.e. it hardens when water is added. Here are cement manufacturing process flow chart.

The process is divided in 3 parts:

1. Raw Mill Section 

All the raw materials should be of less than 25 mm size. If the size of the raw material is bigger than 25 mm, It has to be crushed through a crusher and Hammer Mill. All the materials are crushed stored in the storage yards through belt conveyors.

Now, the raw materials are taken as per their required percentage with the help of a weigh belts( Control by PLC ).The measured materials is went to feed belt conveyor and after that shifted to a feed hopper through elevator .The feed of material is controlled with the help if ratchet Feeder/Table feeder.

2. kiln Section 

From Surge silo the mixed raw materials are taken to Nodulizer with the help of a screw conveyor.Then water is sprayed on the mix (10%) to make nodules with the help of nodulizer. These nodules are fed into the kiln through feed chute for burning and Fusion. The temperature goes up to 1350OC in the burning zone. The material travels very slowly in the kiln. All the material get fused here. After passing through the burning zone the material starts cooling slowly. The Clinkerisation starts and the clinker finally comes out of the kiln.

3. Clinker Grinding Section 

The clinker so obtained is crushed to make its size less than 25 mm. The crushers/Roller crusher are used to crush the clinker. The Gypsum is used as an additive. Both material crushed together and went into feed hoppers through elevator. They are collected through the feeders provided below the feed hoppers. The clinker and gypsum are mixed in certain ratios (5%). So, the weigh belt is used to weigh the ingredients for mixing. A modern electronic weighing & control system may also be used to weigh and measure the ingredients The ratchet/Tables feeder is used to control the feed in the mill and control the fineness of the Cement.

The ground Cement is taken to the aeration and storage silo with the help of elevator or air lift.The aerated Cement is filled in 50Kg bags with the help of packing machine. The product is stored in the godown through belt conveyor and stacking/dispatched as per requirements. The pollution control equipments are necessary as there may be dusting in the plant.

● If something abnormal happens, for instance, the iron is fed into the crushing chamber or there is a jam in the chamber, the up-cover of the machines will be lift up and the materials will be discharged automatically, thus eliminating the chance of machine stoppage to discharge the material by workers. Besides, it’s easy to maintain, and the cost is much lower than Spring Cone Crusher.

Impact crusher is a new type of high efficient crusher machine

Impact crusher is to use counterforce for crushing, when the material put into the impact board and the crushing chamber by rotation of the rotor to gain momentum in the impact plate and the rotor back and forth between the impact of back chamber, respectively, by the first stage, second stage and the bottom of the back cavity of the gradual crushing grinding chamber to the required fineness.

 Impact crusher can adjust the output particle size in many ways, sucha as adjusting the rotor speed, adjust the gap between impact plate and grinding chamber. Gap adjustment can be mechanical or hydraulic adjustable, hydraulic control system can easily operate the button or through the local control system to complete the gap adjustment. The hammer crusher to adjust the output particle size can only be achieved by replacing the bottom of the sieve. The wear part in blow bar of  impact crusher for sale only appears in the side facing the input material. When the rotor speed is normal, the feed material will fall to the surface of blow bar, back and side panels are not being worn, even the side facing the input material has little worn. And the bottom of the grinding rod is also very easy to replace. The metal utilization on blow bar of impact crusher can reach 45% -48%.

And with the same cage crusher and hammer crusher production capacity, power consumption, repair and maintenance and other aspects of comparison, impact crusher are superior in the cage crusher and hammer crusher, impact crusher is not only simple in structure, power consumption provinces, crushing ratio, uniform particle size but also in terms of more unique superiority.
