Production process and main equipment of cement plant

2021-04-05
Cement production method       The production process of cement is simply two grinding and one sintering, that is, raw materials are mined, crushed, ground and mixed to produce raw materials. Raw materials are fired at 1450 ~ C high temperature to produce clinker. Clinker is crushed and ground together with gypsum or other mixed materials to become cement. Due to the difference between dry and wet raw meal preparation, the production methods are divided into three types: wet process, semi dry process or semi wet process and dry process. 幻灯片3 Characteristics of wet process producti...

Grinding system energy consumption and fine management

1970-01-01
Eliminate sick functioning is a premise of fine operation , grinding system of sick functioning performance mainly are: 1. instability of raw material.  2. high consumption of grinding body . 3. grinding in poor ventilation. 4. high deviation of product quality.   Instability of raw material: Stability of limestone and other auxiliary material: particle size, water, etc.. Stability of clinker quality. Use free calcium oxide measure quality.   High consumption of grinding body: Mixed loading with steel balls of different quality. Can't  clearance regularly; Diaphragms plate and export sieve...
