The starting point for ball mill media and solids charging generally starts as follows: 50% media charge. Assuming 26% void space between spherical balls (nonspherical, irregularly shaped and mixedsize 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% ...

4 driven approach now widely used are: threephase AC motor hydraulic coupling gear reducer Pulley reducer. As a ball mill is a constant torque load, in a fluid coupling speed, its speed efficiency equal speed ratio, a large part of the energy that also left coupler is wasted, increasing the milling consumption, services: responsible for each process, for each product, for every ...
where d is the maximum size of feed (mm); σ is compression strength (MPa); E is modulus of elasticity (MPa); ρb is density of material of balls (kg/m 3); D is inner diameter of the mill body (m).. Generally, a maximum allowed ball size is situated in the range from D /18 to D/24.. The degree of filling the mill with balls also influences productivity of the mill and milling efficiency.
