XMB series rod ball mill is an efficient laboratory grinding equipment for wet grinding of ore or other materials. Steel balls can be used as grinding medium instead of steel rods. In rod grinding operation, particle sizes of final product are relatively uniform and ore overgrinding can be eliminated.
Rod mill is suitable for coarse grinding, when product granularity is between 1 to 3mm, processing capacity of rod mill is bigger than ball mill with same specification. 3. Rod mill has certain selective grinding effect because grinding media of rod mill and ores is in line contact.
Rod mills are grinding machine which employ high carbon steel or special steel rods of nearly the same length as that of the drum, in place of steel balls in ball mills. Rod mill products are generally coarser than those produced in a ball mill, and rod mills are well suited to handle coarser feed and to control the top size of the product.

A Grinding Ball mill 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. A Grinding Ball mill consists of a hollow cylindrical shell rotating about its axis.
The Rod Mill is the same as the Ball Mill in the construction and available to both of wet and dry processing. Unlike the Ball Mill, however, the Rod Mill uses rods instead of balls as the grinding medium. As a result, its uses are different from those with the Ball Mill.

Coal Ball MillCoal ball mill is the equipment used for grinding and drying coal with different hardness. It is mainly composed of feeding device, principal axis, rotating part, transmission part, discharging part, high-pressure starting device and lubrication system.
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.
A ball mill is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium.
Our Ball, Tube and Rod Mills are designed for open or closed circuit grinding under the most severe and exacting conditions. PATTERSON offers a variety of Steel or Ceramic Jar Mills and Mill Jars ranging from 0.12 USG to 6.6 USG for laboratory, research and development use.
