Horizontal ball Mill grinds material by rotating a cylinder with steel grinding balls, causing the balls fall back with the cylinder rotating and drop on the material to be ground. The rotation is usually between 20-40 r/min, depending upon the diameter of the mill.
rotation and, therefore, exerting shearing forces on the adjacent slurry. As a result, both liquid shearing force and media impact force are present. Such combined 2. ... Ball mills are one of the more common mills and use a closed cylindrical container that is
Am sure your Ball Mill is considered the finest possible grinding mill available. As such you will find it is designed and constructed according to heavy duty specifications. It is designed along sound engineering principles with quality workmanship and materials used in the construction of the component parts.
The basic construction of a ball mill is a cylindrical container with journals at its axis. The cylinder is filled with grinding media (ceramic or metallic balls or rods), the product to be ground is added and the cylinder is put into rotation via an external drive causing the media to roll, slide and cascade.

The operating principle of the ball mill consists of following steps. In a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media.
A 3D ball mill(3D Reactor) is a ball mill having two longitudinal and transverse axes, like a gyroshin single.Since balls move in random directions by adjusting the rotation of the two axes, we have made it possible to efficiently pulverize using the whole container rather than a rotation planetary ball mill.
Applied material: Energy saving mining ball mill is a key equipment in beneficiation plant.It is widely used in ore dressing production line such as Gold ore, Cooper ore, Magnetite ore, Antimony, Calcite, Kaolin, Mica, Clay, Bentonite etc Ferrou metal or Nonferrous metal materials.
The operating principle of the ball mill consists of following steps. In a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls.
