The products from AG or SAG mills ordinarily feed secondary grinding mills with particles that range in size from five cm down to beneath 100 microns (0.1 mm). The final particle size is determined by downstream processing needs. Grinding is carried out as a wet course of action with water content between 50 - 70% by weight. >

Rod mills are lengthy cylinders filled with steel rods that grind by compressive forces and abrasion. The length of the cylinder is ordinarily 1.five to 2.five occasions longer than the diameter. As the mill turns, the rods cascade more than one another in somewhat parallel fashion. A single on the key positive aspects of a rod mill is the fact that it prevents over-grinding of softer particles because coarser particles act as bridges and preferentially take the compressive forces. Rod mills can take particles as coarse as 5 cm. A lot of the newer operations are likely to install s in mixture with SAG mills and avoid rod mills due the price of the media, the price of replacing rods and common upkeep charges. Numerous older operations have rod mills in combination with ball mills.

Ball mills really are a similar shape to that of your rod mills except that they're shorter with length to diameter ratios of 1 to 1.five. Because the name implies, the grinding media in these mills are steel balls. The particles size with the feed usually doesn't exceed 2.5 cm. The grinding is carried out by balls getting carried up the side of the mill such that they release and fall towards the point exactly where they impact the ore particles in trailing bottom region from the slurry. In the event the mill is rotated too quickly, the balls is often thrown as well far and just strike the far end on the mill and conversely, if the mill is rotated to slow, the efficiency with the grinding procedure considerably reduced.

Ball mills are suited for finer grinding as greater particles do not impede the impact on to smaller sized particle as in rod mills....
