Working Principle:
Ball milling machine 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.

Performance:
1. The new ball milling machine can save power of motor of 30-40%,
lubricating oil 70%, cooling water 90%, and the comprehensive saved
energy is over 40%.
2. The headstock of the ball milling machine does not need to change,
which saves much maintenance costs and both time and labor.
3. The headstock adopts grease lubrication which is convenient, clean
and with no heavy metal pollution.
