Application of ball mill machine: Ball mill is used for grinding of various ores and rocks, widely used in non-metal mines, ferrous and non-ferrous metal mines, construction material, hydraulic engineering etc. 1. Iron ore beneficiation line 2. Copper ore beneficiation line 3. Gold ore beneficiation line 4. Lead-Zinc ore beneficiation line 5. Fluorite ore beneficiation line 6. Iron slag grinding line 7. Cement clinker grinding line 8. Graphite powder grinding line Working principle of ball mill machine: There are many grinding medium balls inside the continuous rotating drum (there are many rods inside the rod mill). The continuous feeding material is broken by the shooting balls which are coming from a certain height of the wall of the drum; The falling medium and material would produce irregular slip and roll during the rotation of the drum, and the material is pulverized fine by the grinding effect among medium, drum-lining and materials. The dynamic material level different is produced by continuous forced material charge and discharge, consequently more and more fine material is slow out from the drum, and finish the grinding process inside the drum.
