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 CenterPeriphery Discharge mill has feed reporting from both ends and the product discharges ...

Ball mills are built in Overflow and Diaphragm types. In the Overflow mill the material is discharged by new feed moving into the mill and displacing a mixture of solids and water being ground within the mill. The diaphragm arrangement in a ball mill is a positive means of pumping pulp or dry material out of the mill.

Average material height above the ball surface level (18 cm) and free height of the mill ( m) were measured to be used in mill powder load (holdup) calculation ahead of collecting the samples along the long axis of the mill at the crashstop condition. Mill filling was calculated to be 32% using the mentioned geometrical measurements.

According to Souza et al., when a ball end mill is used, the roughness parameters measured on a freeform surface can be affected by the material cutting mechanismshearing or plowing. Machining through the center of the tool can have a negative effect on the final surface quality in terms of surface roughness or surface topography [ 22, 23 ].
