2015-4-16 · Figure 2 shows that there is no linear relation between mill absorbed power and ball filling degree. As indicated on the graph, a small variation in power could be the result of a significant variation of balls filling degree. As the ball wear rate depends directly on the surface of the media charge, a small variation in power will lead to an

Steatite Ceramic Grinding Balls and Media | Steatite ...

Steatite ceramic balls and mill lining bricks are manufactured from the same fine-grained composite and are ideal performance partner. Thus, they retain their shape better and last longer than flint / river pebbles, natural stones, porcelain etc. Due to their higher density, hardness, toughness and a higher degree of sphericity, Steatite ceramic grinding media saves over 20-25% milling time ...

MillTraj Liner Design Software

MillTraj Liner Design Software. MillTraj utilises a model based on the correct analytical solution of the physics of motion of particles to predict the motion of the outermost grinding media in a rotary grinding mill, as affected by the design of the lining.

Ball mill media optimization - Metcom Tech

2018-12-4 · • Test mills used for media sizing investigations need to be reasonably large (at least 0.4 m in diameter was suggested), depending on size of balls and ore being tested. • Ball surface wear rate is approximately constant, but with variations due to hardness, and other factors. Consumption is closely related to total ball charge surface area.

2016-11-18 · The material charge is equally important in running an efficient milling operation. If too little material is loaded with the media, it will mostly stay in the voids between the media and the media will just grind against each other. Too little material will cause excessive wear on the media

Ball Mill Loading - Dry Milling - Paul O. Abbe

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
