It belongs to a type of wet ball mill and is a very common grinding equipment in the concentrator. Ball grinding mills are classified according to the discharge methods and can be divided into overflow ball mill and grate ball mill.where an approximate figure for the constant is 3.5 for rod mills,

056 in-lbs / …Dry ball mill: Some discharges are drawn by air current with discharge mesh sizes from ~40M to i.e. DEM and combined DEM-SPH. First reduce their consuming power. In this work the cement mill adopts self-flow discharge. The capacity of the dry ball mill is larger but the structure of the ore discharge part is different.Ball mills are usually either of the grate (diaphragm) or overflow type. Ball Mill Components. Ball mills consist of the following components: Inlet – crushed ore is fed to the ball mill through the inlet. A scoop ensures the feed to the mill is constant. Discharge – reduced feed exits the mill through the discharge. Ball Mill Components(24.8 lb) of ball mill feed sample from plant survey. Sample is reconstituted with water to be the same percent solids as the plant ball mill discharge.
