High Efficient Mining Ball Mill Machine For Mineral Grinding
Working Principle Of Ball Mill
Ball mill is the cylindrical swiveling mechanism. It is the outside gearing, double-hopper and lattice ball milling machine. The materials are transferred into the first hopper of the ball milling machine by quill shaft screw of the feeding equipment. This first hopper has the stepped lining board or corrugated liner board, and the steel balls with different specifications. When the cylinder rotates, centrifugal force will come into being and lift the steel ball to a certain height. Then, the steel balls will fall down, and have strike and grinding impact on the materials. After kibbling in the first hopper, the materials will be transported into the second hopper by single-wall partition. The second hopper has the steel balls inside the scaleboard which will make further grinding to the materials. The powder will be pulled out by the discharging grate plate and accomplish the grinding..

Rod mills Working Principle
The rod mill 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 ripple liner and different specifications of ceramic ball in the chamber. The centrifugal force caused by rotation of barrel brings the ceramic ball 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.
Application
Rod mill is applied to metal and nonmetal mine, water conservancy and glass building materials grinding various ore, rock and artificial sand which needs product granularity evenly.
Rod Mill--bar Mill Application:
Rod mill are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reduced. It is widely used in building material,ceramic raw material, chemical industry, etc,can be used both dry and wet.
