This inadvertently increases the surface area of the coal, thus enhancing the combustibility in the furnace chamber of the boilers. Bowl mills work predominantly on the principle of crushing. An AC motor coupled to a pinion shaft transfers the torque to worm gear mounted on the vertical shaft.

To reduce bearing contamination from other sources, all parts of the housing, shaft and gears should also be thoroughly cleaned. After the bearing has been cleaned, it can be dried with compressed air, taking care not to let the bearing spin. After cleaning, the bearing should be carefully inspected for damage and wear.

Milling is the process of machining using rotary cutters to remove material by advancing a cutter into a work piece. This may be done varying direction on one or several axes, cutter head speed, and pressure. Milling covers a wide variety of different operations and machines, on scales from small individual parts to large, heavy-duty gang milling operations.

A VSI mill (vertical shaft impactor mill) is a mill that comminutes particles of material into smaller (finer) particles by throwing them against a hard surface inside the mill (called the wear plate). Any hard or friable materials can be ground with low value of metal waste. This type of mill is combined with a classifier for fine tuning of a product size.

 · TYPES OF MILL • Tube or ball mills: These are low-speed machines that grind the coal with steel balls in a rotating horizontal cylinder. • Vertical spindle mill: These are medium-speed machines that include bowl mills, ring roll mills, and ring and ball mills. The bowl mills are further divided into deep bowl or shallow bowl mills.

The vertical spindle is free to rotate around its own axis. The crusher illustrated is a short-shaft suspended spindle type, meaning that the main shaft is suspended at the top and that the eccentric is mounted above the gear. The short-shaft design has superseded the long-shaft design in which the eccentric is mounted below the gear.
