The Raymond® Bowl Mill is considered the finest vertical roller mill available for pulverizing coal. The typical Raymond bowl mill system is designed to simultaneously dry, pulverize, and classify solid fuels to 95% passing 200 mesh (<5%R75μ) with a wide range of capacities from 24 to 150 stph.
The resulting coal build-up can lead to hazardous conditions such as mill fire or explosion. Basic studies conducted at different pulveriser manufacturers [2], [3] across the world have shown that there were unequal velocities in the flow at classifier, due to which, repeated grinding causes concern for rollers' lifespan.

The coal mill is a vertical roller mill, in which the coal particles are collected in a bag filter through a grit separator. The required size of coal is 80% of 90 μm and less than 2% of 212 μm (Atmaca and Yumrutaş, 2014). Hot air generated in a coal-fired furnace or from a cooler/pre-heater is used for drying the coal in the mill.
Operation. The coal is feed into the coal mill through a central inlet pipe where gravity is used to lead the coal to the bottom of the mill, where the grinding table and some heavy rollers pulverizes the coal to particles. The primary air flow to the furnace is fed through the mill, with the purpose of heating and lift the coal particles out ...
The most used coal mills in cement plants are air-swept ball mills and vertical roller mills. At present, most cement plants use coal as the main fuel in the clinker production process. The standard coal consumed by the new dry process for producing 1 ton of cement clinker is usually between 100 kg and 130 kg, and the fuel cost accounts for ...
