Grinding Media. Grinding Steel media is used in these processes to grind or crush material to both reduce particle size and refine material. Normally, carbon steel balls AISI 1010 & AISI 1085 are used for common low speed grain grinding such as metal or chemical powders.
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 ball mills designated as 5′ x ...
When corrosion resistance is required, 304 or 316 stainless steel grinding media balls should be used. Compared to stainless steel balls, the Chrome Steel Balls offer superior wear resistance, high hardness and high load bearing capacity as a result of through-hardening. Standard balls meet bearing ball grade 1000.
The grinding media is contained in a cylinder (basket), and the mill base is circulated through the basket. The VMA-Getzmann basket mill consists of a stainless-steel cylinder with an opening at the top and a sieve filter on the bottom. The standard diameter size of the grinding media is 1.0 mm. however, it can be ordered to use 0.3 mm bead size.
