Evaluation On The Improvement Technology Of Cement Grinding System

- Apr 15, 2019-

In order to improve the capability of front-line technicians and managers in the cement grinding system to optimize the system and control the efficient and low-consumption operation of the system, in the "fourth China cement industry grinding system optimization and transformation technology seminar" in 2018, participants evaluated and discussed the practical technology of the cement grinding system optimization and energy-saving transformation.


1energy-saving renovation technology to increase the capacity of the pre-grinding system.


To increase the pretreatment capacity before grinding, the power of roller press/tube mill is required to be 1.0, so as to give full play to the advantages of high efficiency bed grinding technology.


2new liner technology of tube mill.


Under the condition of constant working speed of tube mill, the shape and size of lining surface are related to the grinding efficiency of tube mill.Serious wear of lining plate can reduce production by 10% or 20% and power consumption of grinding by at least 2% or 5%.


3three-dimensional activation technology of abrasive body.


The purpose of installing the activation ring in the fine grinding bin of the tube mill is to better eliminate the "stuck belt" of the grinding body, activate the effective grinding work of the micro segment or small ball in the grinding movement, improve the grinding degree of cement, and reduce the fineness of cement products (sieve residue).The three-dimensional activation technology of abrasive body can increase the activation space and area, activate the grinding energy of small-size abrasive body more, and improve the grinding efficiency
