 Overview

Traditional clinker grinding unit adopts ball mill to grind clinker, and has much dust, loud noise and high energy consumption in the process of production, it will be replaced gradually by vertical roller mill

Clinker grinding processing：

Clinker 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.

The electric motor drives the disc through the reducer, and the hot air enters the vertical roller 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 roller 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 and the rotor speed of the separator, can achieve the required product thickness.
