Rotary Ball Mill for Industrial Grinding Dry and Wet Types

The rotary ball mill is a kind of traditional ball mill machine. Different from the vertical ball mill, it adopts a horizontal barrel type rotating structure. There are two types of rotary ball mill: dry type and wet type, which can be chosen by users according to their actual situation.

Our company adopts advanced controllable feeding and discharging technology, combined with the actual grinding materials, equipped with grinding media (steel balls) of appropriate size. When the rotating ball mill grinds the material, the traditional surface contact is changed to the line contact, resulting in more uniform particle size and higher output.

The rotating ball mill is widely used in grinding operations with high requirements on the uniformity of finished products in refractory, chemical, metallurgical, and glass industries. In recent years, it has also been used in the sand making industry of construction sand.

The grinding principle of the rotary ball mill differs from:

• Vibration ball mills which use high-frequency vibration of the cylinder
• Attritor ball mills which use an agitator to stir the grinding media

The rotary ball mill uses the rotary motion of the cylinder to drive the grinding steel balls to fall after reaching a certain height, producing a heavy blow and grinding effect on the material.

Rotary ball mill is composed of:

• Feeding part and discharging part
• Turning part
• Transmission part (reducer, small transmission gear, motor, electric control)

Key structural advantages:

• Hollow shaft made of cast steel
• Removable and replaceable lining
• Large rotary gear processed by casting hobbing
• Cylinder equipped with wear-resistant lining board
• Smooth, safe, and reliable operation

The barrel is divided into two bins with a grid liner at the discharge end. Customers can choose between dry grate or wet grate rotary ball mill configurations.

We provide free trials of our rotary ball mills and can design various beneficiation processes. Contact us for more information.
