Again following Stokes Law, the smaller themedia, and the greater it surfaces area to and the slower its velocity falling through the fluid. Common starting points for the viscosity limits: 1000 cps for aluminamedia2000 cps for steelmediaThe starting point forball mill mediaand liquidchargingis generally as follows: 50%media charge
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% to 25% product loading.
