This ball mill is typically designed to grind mineral ores and other materials with different hardness, and it is widely used in different fields, such as ore dressing, building material field, chemical industry, etc. due to the difference of its slurry discharging method, it is divided to two types grid type ball mill and overflow type ball mill.
For overflow ball mills, the charge should not exceed 45 of the mill volumeor grate discharge mills, the charge should occupy about 50 of the mill volumeond developedelationship that can be used to determine the percent charge by volume asunction of the vertical height above the charge, he, and the radius of the mill, r, i.e.,.
In general, wet stirred mills impart higher power density than planetary mills and rotating ball mills, and achieve the production of nanosuspensions faster. regardless of milling equipment,onger milling process usually allows for the production of smaller particles 5,47,97.onger milling is associated with more beadbead collisions.
