The document describes a ball mill machine made by Henan Leili Mining Machinery Co., Ltd. A ball mill is used to grind materials into a fine powder in various industries such as mining. It works by grinding materials into powder using steel balls inside rotating cylinders. Materials are fed into the first hopper and ground by impact and friction as the balls fall. Finely ground powder is discharged through grate plates while coarser material moves to the second hopper for further grinding. Ball mills offer improved energy efficiency over older models, reducing power consumption by 30-40% and using 70% less lubricating oil.

Ball Mill
Ball Mill Application:
Ball mill machine is widely applied in the industries, such as cement, silicate product,
refractory, fertilizer, mineral processing of ferrous and nonferrous metal and glass
ceramic, etc. It is mainly used to make dry or wet powder grinding of various ores and
other grindable materials.

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.
