Detailed Description of Rod Mill:

Rod Mill grinds material by rotating a cylinder with ceramic grinding balls, causing the balls to fall back into the cylinder and onto the material to be ground. The rotation is usually between 4 to 20 revolutions per minute, depending upon the diameter of the mill. The larger the diameter, the slower the rotation. If the peripheral speed of the mill is too great, it begins to act like a centrifuge and the balls do not fall back, but stay on the perimeter of the mill.

Working Principle of Rod Mill:

Therod millis 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.

The Main Features of Rod Mill:

1.Applicable for fine crushing and coarse grinding but not prone to over-grinding 
2.Compared to old style mill, EPIC rod mill could save energy by over 40% with quite obvious power saving advantage. Moreover, we could further save energy by 10-20% and increase production capacity by 20% by using the rolling bearing 
3.Compared with common ball mill, the grinded particle is more even. Also the wear rate and replacement rate for steel rod is much lower than our competitor since we always carefully select the best quality rod mill.
