The four most common coal pulverizers types are: Ball-Tube Mills This type of mill consists of a rotating tube filled with cast alloy balls. Coal is introduced through two hollow trunnions on each side of the tube. As the tube rotates, the balls tumble onto the coal, crushing and pulverizing it. Impact Mills
The purpose of the coal drying system is drying and grinding the raw coal for stable transportation of pulverized coal to gasifier and stable/high-efficiency gasification at the gasifier. In the same way with conventional coal firing boiler, raw coal fed from coal bunker is dried and grinded in the coal pulverizer.
Crushers, Pulverizers & Mills. Particle-size reduction, or comminution, is often required to prepare bulk material samples for testing. Crushing is often the initial step with materials such as mineral ores or aggregates using varying combinations of force, impact, and compression to initiate fracturing in the materials.
"Pulverization" (comminution, crushing, grinding) is the process of applying an external force to a (solid) material of a certain size to destroy it and reduce it into pieces that are smaller than the original size. Pulverization has long been done for many materials, including ore, glass, ceramics, grains, paints, and medicines.

A high-quality hammer crusher can keep final material passing a twenty mesh, fifty to sixty percent passing a fifty-mesh screen. Crusher hammers are high chrome content. The hammer service life depends on the material you process. If you're running abrasive quartz, they'll last somewhere between one to two weeks.

To efficiently combust coal, it needs to be pulverized into fine particles (100μm) before being placed in a boiler. A pulverizer (coal pulverizer) is installed for this purpose, and pulverizes pieces of coal several centimeters in diameter down to fine particles. The pulverizer includes pulverization, drying and classification functions.
