Cement ball mills typically have two grinding chambers. The first chamber is filled with larger diameter grinding media andlined with lifting liners . The first chamber coarse-grinds the feed material and prepares it for the second chamber. The second chamber is the fine grinding chamber.
General rule #1: Feed particle size should be 90% < 10x bead size. Example: 2.0 mm bead will have a feed size of 90% < 200 micron. General rule #2: final particle size will be 1/1000th of media size. Example: 2.0 mm bead will give a D50 of 2.0 microns.

Grinding Media. ME Elecmetal designs, manufactures and supplies the highest quality forged steel grinding media for SAG and ball mills in the world.
New advances in ceramic grinding media provide many manufacturing benefits and justify the higher bead cost. Higher density, increased hardness, smoother surfaces, and uniform bead size provide long bead life and low wear on equipment. These characteristics will help when milling with smaller diameter beads, typically less than 1 mm diameter.
