Aug 05, 2021 Types Of Coal Pulveriser. Slow speed mills like ball mill. Medium speed mills like bowl mill. High speed impact mill. The slow speed and medium speed mills are selected for coals ranging from sub-bituminous to anthracite. The high-speed mills are used mainly for lignite.
Aerated ball tube mills are designed for anthracites, coal, lignite, shale and other materials grinding up to pulverized condition and for continuous operation in coal pulverization systems at thermal power plants and other branches of industry. The coal grinding process in aerated mills is performed simultaneously with coal drying inside the drum. Coal together with drying agent is fed into the drum through the coal feeding branch pipe, and finished pulverized coal.

Thermal Power Plants. These are normally mono chamber drum type structure, in which balls (of certain sizes) are fed and then the Drum Mill is rotated at a critical speed such that balls stick on and reach top (theoretically) or almost top and fall with gravity on coal, there by crushing it. Tube Mills is lined with Liners so that the mill.
