percent of steel balls in ball mill

Generally, the newly installed ball mill has a running-in process. During the running-in process, the amount of steel balls is added for the first time, accounting for 80% of the maximum ball load of the ball mill. The proportion of steel balls can be added according to the size of the steel balls (ф120mm, ф100mm, ф80mm). , Ф60mm, ф40mm)

    Effects of percent solids and mill loading on ball wear in

    The effects of percent solids, mill loading, and grinding time on product size distribution and ball wear were studied in a laboratory ball mill for a taconite ore. Mild steel balls and HCLA steel balls were used to examine the role that ball hardness play in grinding. Net production of −44- m (−325-mesh) material reached maximum at 70% solids, whereas the ball wear decreased as pulp

    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%

    For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 30-45%). Pulp (crushed ore and water) fills another 15% of the drum’s volume so that the total volume of the drum is 50% charged. Pulp is usually 75% solid (crushed ore) and 25% water; pulp is also known as ‘ slurry ’
