Prominer provides ball mill / rod mill grinding system which is widely used in various types of ores' beneficiation, electricity, cement and chemical industries. It can carry out dry or wet pulverizing and can meet demand for sustainable largescale production.
Volume Load
The measurement of the ball charge volume load (or filling degree) is essential to maintain the absorbed power of the mill and consequently the mill production. The most common way to evaluate the filling degree is the measurement of the free height inside the mill (vertical distance between the top of the charge and the lining in the mill axis).
Ball Mill Loading
The starting point for ball mill media and liquid charging is generally 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 45% to 50% above the ball charge for total of 58% ...
