PDF Coal Pulverizer Design Upgrades to Meet the Demands of Low Noox Burners

A modern MPS mill design is equipped with a hydropneumatic grinding force loading system that consists of three hydraulic cylinders with one tension rod each to pull down a rigid loading frame. The grinding rollers fixed to the loading frame are thus pressed against the coal bed between the rollers and grinding table segments (Figure 4).
