The equipment of ball mill used in cement plant includes vertical cement mill, roller press and ball mill, etc. The cement ball mill in cement plant is usually divided into 2-4 silos, the most representative of which are the "new type of high fineness cement ball mill" and "open flow high fineness cement ball mill".
The power ingesting of a grinding process is 50-60% in the cement production power consumption. The Vertical Roller Mill (VRM) reduces the power consumption for cement grinding approximately 30-40% associated with other grinding mills. The process variables in cement grinding process using VRM are strongly nonlinear and having large time

Vertical coal grinding mill integrates crushing, drying, grinding, powder selection and conveying.; It has simple system and compact structure. Vertical coal mill covers an floor area about 50% of the coal ball mill with the same specification.; Coal vertical mills can work in open-air environments, greatly reducing the cost of investment. The design of the vertical coal mill system is simple ...
If we instead focus on wet grinding, we should differentiate between stirred media grinding, which can be both vertical and horizontal, and tumbling mills with manufactured grinding bodies. A continuous grate-discharge tumbling mill with grinding balls does seldom have ball size below 20 mm since you then will have unacceptable media losses or ...
