Planetary Ball Mill Working Principle. Planetary Ball Mills consist of several cylindrical grinding jars (positioned on the sun wheel as shown on the figure) which are filled with loose grinding balls. Two superimposed rotational movements move the grinding jars: Like in a planetary system the grinding jar rotates on a orbit around the centre.

Ball mill is a type of grinder machine which uses steel ball as grinding medium, can crush and grind the materials to 35 mesh or finer, adopted in open or close circuit. The feed materials can be dry or wet, they are broken by the force of impact and attrition that created by the different sized balls.

By contrast, the principle of the vertical mill is to apply forces to a thin material bed, which lies between the mill table and the rollers. The high pressure forces, supplied by a hydraulic system on the rollers, cause the individual particles within the bed to fracture. This type of grinding is much more efficient than the ball mill system ...

Design and operating principle. A ball mill is a hollow drum rotating around its horizontal axis. It is filled with grinding balls (impact elements). As a result of rotation, balls on the internal drum surface lift and then fall down under the gravity action. The source material is permanently fed through one of spigots.
