Coal is often the main fuel source used to heat the cement kiln. Coal pulverizers are required to grind the coal from the bulk storage size to a smaller particle diameter to use in the kiln. Coal pulverizers significantly reduce the mean particle size of the coal, drastically increasing the fire explosion.

Introduction. This article concerns itself with vertical grinding mills used for coal pulverization only (coal pulverizers), although vertical grinding mills can -and are- used for other purposes The 3D model in the saVRee database represents a vertical grinding bowl mill.Other grinding mill types include the ball tube mill, hammer mill, ball and race mill, and , roll and ring mill.
The layout of your coal grinding system must take into account the available heat sources for drying the raw coal as well as the fire and explosion hazards of coal and coal dust. The entire grinding plant must therefore be shock-resistant and equipped with a number of explo-sion relief valves. From the raw coal.
The coal mill grinding system is an important part of the dry process cement manufacturing. In cement plants, we usually adopt the air swept coal mill system or vertical mill system as the pulverized coal preparation system, which is arranged at the cement kiln head or kiln tail to provide fuel for clinker calcination. However, due to the flammable and explosive characteristics of pulverized.
