For the coal milling plant five vertical spindle mills (MPS 265) with static classifiers are installed for each boiler. In comparison to the previously used tube mills, the vertical spindle mills provides significant savings in operating and maintenance costs, and the investment costs are also significantly lower.
Vertical Vertical milling machines have a vertical spindle that is similar to the drill press, but with an X-Y table that permits positioning the work. Universal Universal milling machines can be used for either vertical or horizontal milling. The spindle head articulates to allow for either of type of milling operation. Other

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%.
