For the mining industry, our semi-autogenous (SAG) grinding mill uses a minimal ball charge in the range of 6-15 percent. It is primarily used in the gold, copper and platinum industries as well as in the lead, zinc, silver, and nickel industries. Autogenous (AG) grinding mills involve no grinding media as the ore itself acts as the grinding media.

When producing feed for your animals, there are two ways to grind your ingredients to create the perfect feed mix quality: pre-grinding and post-grinding. Pre-grinding means grinding up individual ingredients before you mix them together. Post-grinding means grinding up these ingredients after they've already been mixed together.

Raw coal (sometimes pre-treated) is fed into the centre of the grinding table. The grinding table rotates which causes the coal to move towards the outer periphery of the grinding table. The coal is ground between the rollers and grinding table. When enough coal has been reduced in size, it will flow over the top of the dam ring (retention ring).
