Mill Type Overview. Three types of mill design are common. The Overflow Discharge mill is best suited for fine grinding to 75 – 106 microns.; The Diaphram or Grate Discharge mill keeps coarse particles within the mill for additional grinding and typically used for grinds to 150 – 250 microns.; The Center-Periphery Discharge mill has feed reporting from both …
Conical ball mills are suitable for both coarse and fine grinding. Planetary Ball Mills: These mills consist of a rotating sun wheel and one or more grinding jars, which rotate around their own axis in the opposite direction of the sun wheel. Planetary ball mills are ideal for nano-scale grinding and mixing. Vibratory Ball Mills: Utilizing ...
The grinding chamber is filled up to 70% with inert ceramic grinding media beads. Rotors stir the charge and grinding takes place between beads by attrition. The number of rotors (grinding stages) depends on the application and can be as high as 20. Feed slurry is pumped into the bottom mill.
