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.

Capacity:20-200 T/H Feeding size:25 Mm Output Size:30-400 Mesh Brief Introduction of Ball Mill Grinding: Ball mill Grinding can divide into 2 types, wet ball mill grinding and dry ball mill grinding. Ball mill grinding is a mineral processing machine for milling the materials into powders after they are crushed. Features of Ball Mill Grinding: 1. Suitable for grinding material with high hardness 2. The shape of the final products is circular 3. No pollution for the powder with ceramic ball 4. Stable performance 5. Easy installation 6. The capacity and fineness can be adjusted by adjusting the diameter of the ball Working principle of Ball Mill Grinding: Ball mill grinding is a horizontal rotating device transmitted by the outer gear. The materials are transferred to the grinding chamber through the quill shaft uniformly. There are ladder liner and rippleliner and different specifications of steel balls in the chamber. The centrifugal force caused by rotation of barrel brings the steel balls to a certain height and impact and grind the materials. The ground materials are discharged through the discharging board thus the grinding process is finished.
