In a mining plant or processing mill, they have a big grinding circuit for crushing raw material, these are usually Ball or SAG mills. Inside these Sag/Ball mill are big steel balls that grind ore via an impact process. In simple terms, these hard metal steel balls get to the top of the rotating chamber and fall down crushing the ore being ...
Milling media and grinding media are most popular in grinding processes that involve ball milling equipment such as planetary milling jars and planetary mill machines. Milling balls made of steel and ceramic are our most popular materials. MSE Supplies provides quality, durable, and high performance milling media.
For the first stage of grinding, media will generally be in the 4 to 2 size . In secondary finer grinding the initial charge will begin at around 3 and in the case of balls will grade down to about ¾. Extremely fine grinding will dictate the use of 1½ and smaller balls.

The ball mills are operated at a ball charge volume of 3032% and 78.5% critical speed. The SAG mill trommel undersize is combined with the ball mills discharge and pumped to two parallel packs of twelve 660 mm diameter cyclones. The cyclone underflow from each line reports to a ball mill, while the cyclone overflow is directed ...
The CRRK series of wet grinding rod mills are tabulated below. The grinding charge in a ball mill consist of cast or forged steel balls. These balls are fed together with the feed and consequently ball mills can be in operation for months without stopping. The ball size is often in the diameter range of 20 75 mm.
The grinding media is actually alumina particles held in place by an SiO2 glass phase. Sizes from 400 microns to over 1 inch in beads, balls, satellites and cylinders. Low to medium cost, small sizes are more costly. Fused Zirconium oxide Grinding Media Smooth surface leads to low mill wear and longevity. Sizes from 200 microns to 2.5mm.
