Cement Mill

Cement mill is an important part of the cement plant equipment, as used to grind raw material for production of cement is also called the raw mill or tube mill. Because of its like a hollow tubes called cement pipe mill. Cement mill is mainly used in building material, metallurgy, electric power and chemical industry, all kinds of cement clinker grinding and other materials. The most common cement mill for circuit grinding system, characterized by high grinding efficiency, large power consumption province, mill output, especially grinding of slag cement, the performance of more prominent. General mill output can be increased by 15-20%, and power consumption is decreased about 10%, furthermore, the finished product can reduce the temperature of 20-40 DEG C, the fineness of product is easy to adjust.

Detailed introduction

  • (1) the ordinary cement mill: ordinary cement grinding for most circuit grinding system, the ordinary cement grinding characteristics as high grinding efficiency, large power consumption province, mill output, especially grinding of slag cement, the performance of more prominent. Ordinary cement grinding mill than general yield can be increased by 15-20%, power consumption is decreased about 10%, furthermore, the finished product can reduce the temperature of 20-40 DEG C, the fineness of product is easy to adjust.
  • (2) high yield of superfine cement mill: high yield of superfine cement mill is mainly used in open circuit grinding system. High yield of superfine cement is characteristic of system equipment and process flow is simple, investment province, the plant covers an area of less; the use of advanced internal powder selecting special chamber separating device in the mill structure, fine grinding chamber increases the activation device, the mill tail with a special discharge grate, reduce grinding bin grinding media size to the maximum. Greatly improve the high yield of superfine cement grinding efficiency, achieve high yield, low energy consumption.

After the cement mill is the material being broken, and then smash the key equipment. Cement mill is widely used in cement, silicate products, new building materials, refractory materials, chemical fertilizer, black and non-ferrous metal processing, such as glass ceramics industry production, cement mill all kinds of ores and other materials may be grinding of dry or wet grinding.

To improve the output of cement mill

1. cement mill is set at front of crushing machine;
2. improvement of cement grinding system, improve the efficiency of grinding;
3. for the cement grinding with the high efficiency separator.
