Cement production line crushing and calcination drying equipment
With the continuous heating up of urban construction, 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 cannot be completed by one piece of equipment. It requires a series of equipment division and cooperation to complete the operation. The cement production line is formed by combining these equipment into one production line.
1. Raw material crushing equipment
The first process of producing cement is to crush the raw materials, and limestone is the main raw material for cement production. Because the limestone is quarried, the block is large and the hardness is high, so the jaw crusher that crushes limestone becomes the better raw material crushing equipment on the cement production line. There are many advantages of the jaw crusher enough to prove that it can be used for the crushing production of the cement production line.
① The jaw crusher has two jaws, one moving and one static. The crushing is done by squeezing instead of using impact force. Therefore, the jaw crusher has very low noise during operation and is relatively safe.
②The jaw crusher has a relatively deep crushing cavity and a large crushing ratio, which meets the requirements of high efficiency and energy saving. The product size is very uniform, and there is basically no difference in size.
③The jaw crusher does not have high requirements for incoming materials. As long as the materials that can be put into it, it will “not reject the incoming, hard and soft”.
④The discharge opening is easy to adjust, which provides convenience for the next process.
Cone crushers are divided into many types, including coarse crushing cone crushers, medium crushing cone crushers, and fine crushing cone crushers. Users can choose the appropriate type of cone crusher according to their needs. Cone crusher has many advantages, basically the following aspects:
① The bearing of cone crusher has larger specifications and is more wear-resistant. The increase in the service life of the wearing parts means the increase in profit.
②The main frame of the cone crusher is firm, which means reliable operation and provides a guarantee for safe production.
③The advanced lubrication system of the cone crusher adopts multi-point control and independent thin oil to provide double protection for the lubrication of the bearing.
④The cone crusher is equipped with iron-passing protection device and automatic control system, which realizes safe and reliable automatic control.
⑤The structure of the cone crusher is relatively easy to understand, and it is convenient to disassemble and assemble, which provides convenience for repair and maintenance.
The material is repeatedly crushed in the crushing cavity 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:
①The impact crusher can adjust the discharging particle size and material shape, and manually adjust the gap between the impact frame and the rotor to change the material to obtain the desired material.
②Materials are cubic particles when they come out of the impact crusher, and the bulk density is high.
③The board hammer is made of special materials and has great impact resistance.
2. Calcining and drying equipment
1. Rotary kiln
Rotary kiln is a wide range of building materials equipment. Rotary kilns can be divided into cement kilns, metallurgical chemical kilns and lime kilns according to different materials. Of course, cement kilns are equipment used in cement production lines. The rotary kiln is composed of kiln head, kiln body, kiln tail, support frame, preheating tower, cooler, conveyor belt and other parts. Rotary kiln is an indispensable member of the cement production line. It is not only large in size, large in area, and large in output. Of course, the capital investment in purchasing equipment is also large. Of course, such a “large” equipment cannot be ignored. Understand the market.
From the literal meaning, the dryer is not difficult to understand, it is the dehydration equipment, the dryer is a collective term, each field has different uses, the dryer we are talking about here refers to the material dryer on the cement production line. The heat source of the dryer we use comes from the combustion device. It adopts a co-current heating method, which is gradually heated from beginning to end, and the internal heat exchange is used to complete the drying task.
3. Other supporting equipment
In addition to the main equipment, some supporting equipment is also indispensable, such as cyclone preheater, grate cooler, decomposition furnace, dust removal device, conveyor belt, hoist, etc.
Generally speaking, cement production cannot be completed by any one piece of equipment. Just like an enterprise, although there are more important departments, no matter how important departments do not have the cooperation of other departments, it is impossible to complete all the work. The division of labor is different, and everyone has an important role. The same is true for the cement production line. The equipment on the entire line is very important and indispensable. Only by cooperating with each other and completing their own tasks can the final production tasks be completed.
