According to DSTU 8538:2015, grinding balls 50 HRC after heat treatment should be consistent with the standards shown in table 2 (DSTU 8538:2015), for example, for grinding balls with a nominal diameter of 120 mm, this is at least 50 HRC / 477 HB on the surface. Please note that information about the upper rate is not specified.

According to Moema et al. (2009), in some instances, media wear can constitute up to 40–45% of the total cost of comminution. An estimated consumption of steel grinding media of around 600,000 tons p.a. in the 1980s already gives an indication of the scale of the problem ( Malghan, 1982 ).

Grinding bead diameter. The same composition of grinding media is often available in different size ranges. Typically the larger the in-feed material, the larger the grinding bead you need to use to do the work. It also follows that the finer the grind you need the smaller the grinding bead.

The richest natural source of β-carotene is the paprika for grinding. The small quantities of paprika used as a spice do not meet the β-carotene needs in human food. Since pepper for fresh consumption is consumed in big quantities, it is the main source, which provides β-carotene in the human diet [ 14 ].
