Cement grinding is the stage in which the final product stage in cement production ,it is independent of each other. In this stage, the cement clinker is added with an appropriate amount of the mixed material ,it is be ground to produce finished cement. Cement production generally can be divided into raw material preparation, clinker calcination and cement made of three processes. Silicate cement production process in the production of cement is representative of limestone and clay as the main raw material, by crushing, ingredients, grinding raw materials, and then feed the cement kiln in the calcined mature material, and then cooked Material plus the amount of gypsum (sometimes mixed with mixed materials or admixtures) from grinding.

Cement grinding station Process and host equipment

To achieve an annual output of 600,000 tons of cement, the process can be used to complete the CHAENG (Great Wall Machinery) cement mill.

The main structure of GRMK cement vertical mill consists of separator, grinding roller device, grinding disk device, pressure device, reducer, motor, shell and other parts.

The electric motor drives the disc through the reducer, and the hot air enters the vertical mill from the air inlet. The material falls from the feeding mouth to the center of the disc. Because of the centrifugal force, the material moves from the center of the disc to the edge of the disc. Grinding roller crushed, crushed material continues to move to the edge of the disc until the wind ring at the air flow away, and large particles of material and fell to the disc to continue to crush. The airflow through the upper part of the material separator, the role of the guide vane, the rough material from the cone down to the disc, the fine powder along with the air out of the mill, the dust collector system to be collected powder For vertical mill grinding out of the product. The material is dried in contact with the gas in the housing to achieve the desired dry and wet product. By adjusting the angle of the guide fan blades (small vertical mill is not adjustable) and the rotor speed of the separator, can achieve the required product thickness.
