We have analytically derived a mathematical model of energy-saving ore grinding by a ball mill with a three-phase motion of grinding bodies, invariant to a change in the length of rods during wear. The model can estimate the energy efficiency of grinding larger pieces of ore based on the resulting volume of crushed large-lump material.

Damaged milling ball should be removed in time and estimate for damage and wear degree, and new milling balls should be added. The rotate speed of ball milling machine has a great influence on the ball milling efficiency. If the ball mill rotates at a critical speed or higher, it will not be able to pulverize.

Alumina Balls and Satellites. Union Process is the one source for 90%, 94%, 99.5% and 99.9% alumina media. 90% alumina is available in satellites and rod/cylinders. 94% alumina balls have excellent wear resistance with higher impact strength to save running costs with less contamination. They have great wear rate generally better than 90% or 99 ...

Aug 26, 2021· Ball mills are widely used in the production of new building materials, cement, refractories, non-ferrous metals and glass ceramics. The ball mill has the characteristics of high production efficiency, environmental protection, low grinding cost, continuous production, and wet and dry grinding of different raw materials.

For primary ball mills, F80 may be as high as 10,000 microns. For secondary ball mills, F80 may be as low as 2,000 microns. For alcaline circuits, pH should be close to 10.5. If no lime is added to the mill, natural pH would be around 6.5. Acid circuit applications could run at pH as low as 4.5. Mill Drive transmision losses.

As shown in Figure 4, kilowatt usage can be reduced by as much as 750 kW/day or 8%.

As the ball wear rate depends directly on the surface of the media charge, a small variation in power will lead to an important increase of wear rate. The risk of underloading or overloading the mill is an additional factor. A direct measurement of the ball level in the mill, more accurate than power readings, as well as a control of it, is
