For the mining industry, our semiautogenous SAG grinding mill uses a minimal ball charge in the range of 615 percent. It is primarily used in the gold, copper and platinum industries as well as in the lead, zinc, silver, and nickel industries. Autogenous AG grinding mills involve no grinding media as the ore itself acts as the grinding media.
Rod mill gets its name because its grinding body inside the barrel is steel bar. Rod grinding mill, as firstclass ore grinding machine, is widely used in the first class grinding in industries such as artificial sand, ore beneficiation plant and power sector in chemical plant.
Because of this, the rod mill can effectively reduce 1 feed size to 10 mesh or finer in open circuit. The voids or interstitial space within a rod load are approximately half those in a ball mill grinding load. Rods in place weigh approximately 400 pounds per cu. ft. and balls in place approximately 300 pounds per cu. ft..

Rod mills are mainly used for primary grinding of crushed ore with a particle size range up to 50 mm for soft materials, and between 20 and 30 mm for harder materials where a narrow product size distribution is required e.g. for subsequent gravity separation. Rod mills create a coarser product than do ball mills and typically operate at a slower mill speed.
Horizontal Coarse Grinding Mill Rod Mill Product . Notes The rod charging amount shall be limited up to 38 of the mill s internal volume Capacities listed in the above table are based on tests with ores of Wi 15KWH MT and 80 of mm undersized particles with wet grinding in closed circuit .
Rod mill is similar to ball mills but it uses long rods for grinding media. Autogenous mill is a selfgrinding mill which is used in breakage of larger rocks. SAG SemiAutogenous Grinding mill is an autogenous mill which uses grinding balls, it is similar to ball mill but has large diameter and short length.
The Center Peripheral Discharge rod mill is also used for wet grinding but produces a coarser product than the overflow type. Either the End or Center Peripheral discharge rod mill can be used for wet or dry grinding. Whatever the type, the rod mill is used to produce a coarse product, whereas the ball mill is used to produce a finer product.
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. In other words, the Rod Mill gives impact on and grinds coarse particles present between each rod, while no fine particles receive impact and are ground.
IsaMill Operating Principles. The IsaMill is a stirredmedium grinding mill, in which the grinding medium and the ore being ground are stirred rather than being subjected to the tumbling action of older highthroughput mills such as ball mills and rod mills.Stirred mills often consist of stirrers mounted on a rotating shaft located along the central axis of the mill.

Siempelkamp supplies cast components for horizontal mills, which are used for the coarse grinding of various rock types in order to obtain ores such as gold, copper and iron ore. Vertical mills are used for cement and coal grinding.
Rod mills are very similar to ball mills, except they use long rods for grinding media. The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6.
Ball Mills Mineral Processing Metallurgy. 2020420 Working Principle Operation. The apparent difference in capacities between grinding mills listed as being the same size is due to the fact that there is no uniform method of designating the size of a mill, for example a 5 x 5 Ball Mill has a working diameter of 5 inside the liners and has 20 per cent more capacity than all other
It has been principally designed as a large capacity coarse mill to achieve a 95 less than 250 micron product. This results in a significant improvement in quality of the final sample which will be more representative. The whole sample can be processed in one pass.
Horizontal hammer mill. The possibility of equipping our hammer mill with a broad range of screens is what makes it suitable for your fine and coarse grinding applications with screen hole diameters of 0.8 to 8.0 mm. Reduced downtimes through operatorfriendly maintenance.
