Coal Grinding. To achieve good combustion and satisfactory flame formation, coal needs to be dried and ground to a proper degree of dryness and fineness. Drying of moisture in coal is achieved normally by ducting part of the kiln exhaust gas through the mill with inlet temperatures of up to 300°C. Inert kiln exhaust gases with oxygen content ...

g is the gravitational acceleration in m/s 2, and. r P is the pitch diameter in m.. The optimum of Fr p is between 1.6 and 2.0. The milling capacity for Fr p outside this range is lower despite the constant energy consumption of the pulverizer.. Tests carried out for some industrial mills have proven that the change of grinding unit rotational speed strongly influences mill capacity.

Planetary Mills are ideally suited for fine grinding of hard, medium-hard, soft, brittle, tough and moist materials. The comminution of the material to be ground takes place primarily through the high-energy impact of grinding balls in rotating grinding bowls. The grinding can be performed dry, in suspension or in inert gas.
