Figure 2.27. Cut-away view of the Hardinge conical ball mill showing how energy is proportioned to the work required is about 0.3 kg/Mg of material for dry grinding, and 1-1.5 kg/Mg for wet grinding. The normal charge of balls is about 5 Mg/m3. In small mills where very fine grinding is required, pebbles are often used in place of balls.

Ball Mill Vs Conical Ball Mill
Hardinge mill: In this type of ball mill the cylinder has a conical end towards a discharge point, In this mill, the larger balls remain inside the cylinder and the smaller balls are placed in the conical portion. As a result, coarser grinding occurs in the cylinder portion and a finer grinding takes place at the apex of the conical part.

Conical Ball Mills differ in mill body construction, which is composed of two cones and a short cylindrical part located between them (Fig. 2.12). Such a ball mill body is expedient because efficiency is appreciably increased. Peripheral velocity along the conical drum scales down in the direction from the cylindrical part to the discharge

Overflow ball mill is also called overflow type ball mill. It is a kind of wet ball mill grinder, frequently used in the material refine grinding (finished material is lower than 0.2mm) or the second stage grinding.Overflow ball mills adopt the overflow principle to discharge the qualified material slurry higher than the discharge port naturally.

Cylindrical VS Conical Ball Mills. For coarse grinding the cylindrical grate mill will, as a rule, give a lower consumption of power per ton of ore than a conical mill. The reason for its better performance lies in the low pulp discharge level which reduces overgrinding at the point where it would do most harm—i.e., at the discharge end of
