This paper reports on the contribution of a number of material coal properties and machine operating parameters to the wear of vertical spindle mill components. This assists in the evaluation of mills and coals for particular duties and enables prediction of the likely changes in maintenance regime if these variables are changed. Coal abrasiveness was found to be the most critical coal ...

Vertical Milling. On a vertical milling machine, the cutting head, called the spindle, is oriented vertically. Milling can be controlled in different ways, depending on the specific type of machine. The bed mill uses a spindle that can be raised or lowered, combined with a bed that can be moved horizontally.

1. Vertical Milling Machine. The most common type of mill, the vertical milling machine, has a vertical spindle for attaching milling cutters, such as end mills and face mills, for various milling operations. The machine is used for machining grooves, slotting keyways, producing flat surfaces, and drilling and boring holes.

During the operation of the vertical mill, the motor drives the grinding disc to rotate through the main reducer, which drives the rotation of the grinding disc to rotate the three grinding rollers (120° uniform distribution), and the raw coal falls into the center of the grinding disc through the feeding pipe for grinding and grinding. The company coal internal work through three roller mill ...

The source of the problem is the coal pulveriser mills not being able to produce the more stringent fineness required. This results in coal/char particles burning higher up in the furnace, causing excessive reheater temperatures, etc. One could attempt to increase the rotational speed of the vertical spindle mills by at least 15%.
