Cement production line crushing, grinding, calcining and drying equipmentDate: 2019-06-26 Views:
As the urban construction continues to heat up, the construction of various large and small projects, the demand for cement continues to increase, and the cement industry is booming. The development of the cement industry drives the development of the cement production equipment industry. Cement production can not be completed by one piece of equipment. It requires a series of equipment division of labor to complete the operation. The production line of these equipments is the cement production line. What are the main equipments on the cement production line?
First, raw material crushing equipment
1, jaw crusher
The first procedure for producing cement is to break up raw materials, and limestone is the main raw material for cement production. Since the limestone is mined and the hardness is high, the jaw crusher that specializes in crushing limestone becomes a better raw material crushing equipment on the cement production line. The jaw crusher has many advantages to prove that it can be used for crushing production on cement production lines.
1 The jaw crusher has two movements and one suspension, and the crushing is done by extrusion instead of using the impact force. Therefore, the jaw crusher has low noise during operation and is relatively safe.
2 The crushing chamber of the jaw crusher is relatively deep, and the crushing ratio is significant, which meets the requirements of high efficiency and energy saving. The product granularity is very uniform, and basically there is no case of different sizes.
3 jaw crusher does not require high incoming materials, as long as it can put in the materials, it is "there is no one to refuse, soft and hard to eat."
4 discharge port is easy to adjust, providing convenience for the next process.
2, cone crusher
Cone crushers are divided into many types, including coarse crush cone crusher, medium crush cone crusher and fine crush cone crusher. Users can choose the appropriate type of cone crusher according to their own needs. The cone crusher has many advantages, basically the following aspects:
1 The cone crusher has larger bearing specifications and is more wear-resistant. The increase in the service life of the consumables means an increase in the benefits.
2 The cone crusher main frame is firm, which means reliable operation and guarantees safe production.
3 cone crusher advanced lubrication system, multi-point control can be independent of thin oil, providing double-layer protection for bearing lubrication.
4 cone crusher is equipped with iron protection device and automatic control system to achieve safe and reliable automatic control.
5 The structure of the cone crusher is relatively easy to understand, easy to assemble and disassemble, and provides convenience for maintenance and maintenance.
3, impact crusher
The material is repeatedly crushed in the crushing chamber of the impact crusher until the material is crushed to the required particle size and discharged from the discharge port. This is the advantage that the impact crusher can be formed at one time. In fact, the impact crusher has the following advantages:
1 The impact crusher can adjust the discharge particle size and material shape, and manually change the gap between the counter frame and the rotor to change the material to obtain the desired material.
2 When the material comes out of the impact crusher, it is a cubic particle with a high bulk density.
The 3 plate hammer is made of special materials and has high impact resistance.
Second, cement grinding equipment
The material has been broken into uniform granules, but this is not enough. It needs to be ground by grinding equipment. The milling equipment used in cement production is:
1, ball mill
The ball mill is an early milling machine used in cement production. It is still the main equipment for cement production. Although the ball mill has certain disadvantages, the ball mill is easy to maintain and has high reliability, especially for cement clinker grinding. The shape and grading of the product are suitable, and the cement performance is good. So far, it is difficult to find equipment that can be completely replaced in the milling industry.
2, cement mill
Cement mill is specially used for cement production. The bigger advantage is that it can be produced dry and wet, and it is a wet and dry equipment. The cement mill has a simple structure, energy saving and environmental protection, and its own dust removal system reduces pollution. The more important advantage is that the output is large.
Third, calcination drying equipment
1. Rotary kiln
Rotary kiln is a building material equipment with a wide range of applications. Rotary kiln can be divided into cement kiln, metallurgical chemical kiln and lime kiln according to different processing materials. Cement kiln is of course the equipment used in cement production line. The rotary kiln is composed of a kiln head, a kiln body, a kiln tail, a support frame, a preheating tower, a cooling machine, and a conveyor belt. Rotary kiln is an indispensable member of the cement production line. It is not only large in size, large in area, but also in large output. Of course, the amount of capital invested in purchasing equipment is also large. Such “big” equipment cannot be ignored, and must be neglected before purchase. Understand the market.
From a literal point of view, the dryer is not difficult to understand, that is, dewatering equipment, dryers are collectively referred to, and there are different uses in various fields. The dryers we refer to here refer to the material dryers on the cement production line. The heat source of the dryer we use comes from the combustion device, which adopts a forward-flow heating method, gradually heating from start to finish, and internal heat exchange to complete the drying task.
Fourth, other ancillary equipment
In addition to the main equipment, there are also some supporting equipment, such as cyclone preheater, simmer cooler, decomposing furnace, dust removal device, conveyor belt, hoist and so on.
In general, cement production can be done without any equipment. Just like a company, although there are more important departments, it is impossible for other important departments to complete all the work without the cooperation of other departments. Different divisions of labor, everyone has an important role. The cement production line is also the same. The equipment on the whole line is very important and indispensable. Only by cooperating with each other, each task can complete its own tasks to complete the final production task.
