Production process and main equipment of cement plant
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.
Characteristics of wet process producti...
Standing on a new starting point, Pengfei set sail again
Standing on a new starting point, Pengfei set sail again——Gu Guobiao, Secretary of the Municipal Party Committee led a team to investigate Pengfei Group
n the drastic changes of 2019, Pengfei people were hit by the tide of the global economy. The single-champion advantage of the rotary kiln continued to increase, the total scale reached a new high, and the operating efficiency was steadily improved. On the afternoon of March 9, Gu Guobiao, the party secretary, led a team to visit Pengfei Group for investigation.
2019 is a landmark year in the development history of Pengfei Group. ...
In 2015 overall economic situation fell significantly, cement industry profits fell to the bottom, in order to use "The Belt and Road" and overseas layout to achieve bottoming out, each cement plant will save production costs and the introduction of green environmental protection equipment as the primary bargaining chip. In the process of cement production, cement clinker, materials, slag can be used after grinding, however, the results show that the best grinding efficiency can be achieved only by different materials separately.
1. General situation of "one grinding a...
Cement kiln is used to treat the solid expecting to strengthen the cooperation between industries
The environment situation of our country has become more and more rigorous. Using cement kiln to treat solid waste is a new way to solving this problem which is not only a new direction for cement industry but also attract more attention from the industries causing waste solid.
Senior professor of solid waste treating industry ind...

Grinding system energy consumption and fine management
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...
