Consequently, pebble mills convert less power per mill volume unit than rod and ball mills. High quality steel rods and balls are a considerable part of the operating costs. Autogenous grinding should, therefore, be considered and tested when a new plant shall be designed.
Ball & Rod Mill. Enquire Ball mills and rod mills provide an effective means for grinding and blending materials in preparation for mineral liberation, from rock to dust. These grinding mills may be necessary for improved gold and mineral recoveries. Both ball and rod mills have a hollow cylindrical shell that rotates about an axis.

A ball mill is a type of grinder used to grind and blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.

Rod mills, how they function. Rod mills are very similar to ball mills, except they use long rods for grinding media. The rods . Wet grinding rod mills are normally used in the mineral processing industry. .
Rod mills are less common than ball mills for grinding minerals. The rods used in the mill, usually a high-carbon steel, can vary in both the length and the diameter. However, the smaller the rods, the larger is the total surface area and hence, the greater the grinding efficiency.
The drum mill can be operated either as a Ball or as a Rod Mill by using the corresponding module. A sufficient number of balls or rods is required for an effective grinding process. Typically, a final fineness below 20 microns is obtained.
