The kinetics of dry grinding of several cement clinkers and two coals were investigated in a laboratory tumbling ball mill. The kinetic process is first-order at first, but the rates of breakage decrease as fines accumulate in the bed. It was demonstrated that the slowing of the breakage rates applies to all sizes in the mill, indicating that ...

The starting point for ball mill media and solids charging generally starts as follows: 50% media charge. Assuming 26% void space between spherical balls (non-spherical, irregularly shaped and mixed-size media will increase or decrease the free space) 50% x 26% = 13% free space. Add to this another 10%-15% above the ball charge for total of 23% ...

Using a 254-mm-diameter instrumented ball mill, a series of batch-grinding experiments was carried out dry by Herbst and Fuerstenau, 1968, Herbst and Fuerstenau, 1973 with 7×9 mesh (2.8×2.0 mm) dolomite feed for various operating conditions: mill speeds N*, ball loads M b * and particle loads M p *. Details of the instrumented torque …

Wet autogenous mill is also called cascading autogenous mill. Its structure is shown in Fig. 3. Characteristics: (1) The cylinder has large diameter and short length, but its length-diameter ratio is greater than that of dry autogenous mill and usually 0.3–0.5. (2) The end cover is conical, with cone angle 150 °.

The Wi value from this equation should conform with the motor output power to an average overflow ball mill of 8 ft. interior diameter grinding wet in closed circuit. For dry grinding the work input should normally be multiplied by 1.30. However, ball coating and packing can increase the work input in dry grinding.

Ball mill is an idle tool for grinding many materials into fine powder and it is used to grind different kinds of row materials.There are two ways of grinding, first is dry process and second is wet process. It are often divided into tubular type and flowing type consistent with various sorts of discharging material.
