High Performance Cement Ball Mill For Clinker Grinding 

1. Rational structure, high grinding efficiency.

2. Low investment, few electricity and energy consumptions.

3. Simple and safety operation, reliable and steady performance.

4. Low noise, large capacity, and high economic benefits.

In the techniques of cement production process, people usually choose limestone and clay as the main raw materials to crush, concoct and grind them into cement raw meal, feeding them into cement kiln. Additionally, cement clinker is usually ground using a ball mill. After being calcined, add appropriate amount of gypsum and sometimes add some admixture, then they will be grinded, and the cement will be formed.

Cement mill type:

( 1) open circuit grinding

Ball mill open circuit grinding is the simplest form of technology. Open system has the advantages of simple process, less investment, easy operation and maintenance. Disadvantage is a serious of the over mill grinding phenomenon, low efficiency, high power consumption, difficult fineness adjustment.

( 2) closed circuit grinding

Closed circuit grinding is widely used all over the world in cement production process, United States, Germany, France, Japan and other developed countries almost all large grinding system with closed circuit grinding. For example, more than 95% of total Japanese cement output is by closed circuit grinding system.

Closed- circuit system consists of ball mill, separator and transmission equipment, dust collection equipment and other auxiliary components. Closed- circuit system can eliminate the over-grinding phenomenon,and have the characters of high efficiency, low power consumption ,output than the same specifications of open circuit grinding improved 5% to 50%, convenient fineness adjustment. But the defects are complex process, large investment, inconvenient operation and maintenance.

(3) pre-grinding system

Before the material into the ball mill ,it is pre-crushed by other grinding equipment so as to minify particle size, improve the yield and reduce power consumption of grinding system.
