The cement crusher is the necessary equipment in the cement production line. with the wide application of cement and higher requirement for the cement manufacturing process, the cement crusher gets more and more hot in the cement industry. What’s the function of the cement crusher of the cement plant? How to choose a suitable cement crusher?
How to make cement? Cement is a kind of hydraulic cementitious material, as for the cement manufacturing process, limestone and clay are used as the main raw materials, which is made into raw material by crushing, mixing, grinding, calcined into the cement kiln to make cement clinker, adding an appropriate amount of gypsum (sometimes also add mixed materials or admixture) from grinding. After a complete cement plant, the finished cement is made.
Application of cement crusher
What’s the cement crusher? The cement crusher is used to grind limestone or other materials into required particles. Common cement crushers include jaw crusher, cone crusher, impact crusher, and hammer crusher. In recent years, mobile crusher is popular in the cement plant.
The cement crushing process
The raw material can be broken by extrusion, shearing, rolling or impacting. The crusher works by a single or a group of them.
There are jaw crusher and cone crusher which work by extrusion principle. Hammer crusher and impact crusher working on impact principle. The roller crusher works by shearing and extrusion principle.
The hammer crusher and impact crusher are the most common type used in the cement industry. Both of them rely on the impact principle and also have the function of a coarse crushing, secondary crushing, and fine crushing. The main difference between the two is the striking piece. The former is a hammerhead hinged on the rotor, while the latter is a plate hammer embedded in the rotor body.
In general, the crusher working on the extrusion principle has the lowest energy consumption and the least wear. However, other factors should be considered in the selection of crushers, such as the degree of feed lumpiness and crushing ratio, the ability to adapt to the adhesion of raw materials, the robustness and ease of use of the machine, the one-time investment and operating costs are also important.
