With the development of infrastructure, the cement is in short supply. However, the cement production process is still relatively backward and to speed up the production of cement has become a priority. The limestone and coal gangue are the main raw materials for cement production and they have very wide source. In cement production process, most of the raw materials need crushing such as limestone, clay, iron ore and coal. Limestone is the raw material that has the maximum usage amount to produces the cement. After the exploitation, it has larger particle size and high hardness.

Therefore, there is a need to use the crusher. Impact crusher and sand making machine have effective benefits in cement production. Limestone crushing Governor an important position in the pipes broken in the cement plant.The crushing and processing of limestone conducted by the impact crusher have received the praise of many users, having become the preferred equipment for the crushing limestone. Impact crusher mainly depends on the impact energy to finish the job of crushing materials. When it is in operation, the motor drives the rotor to rotate at high speed in the crushing the cavity. The materials are fed from the upper feeding port and blowed, impacted, sheared and grinded by the hammer in high-speed motion to achieve the ideal of the raw material for cement production efforts. Impact crusher had high cost performance and its features and models are suitable for more industries. Impact crusher is widely used for the crushing operation of limestone, cinder, fly ash, coal and other materials in metallurgy, building materials, electricity, cement, construction, chemical, mining and other industries. Especially in the early stage of cement production, impact crusher shoulders a greater role. Crusher machine:
