Grinding Mill Design & Ball Mill Manufacturer

The ball size is often in the diameter range of 20-75 mm. The biggest size is chosen when the mill is used as a primary grinding mill. For fine grinding of e.g. sands, balls can be replaced by cylpebs, which are heat treated steel cylinders with a diameter of 12-40 mm and with the same length as the diameter.

Brinell Hardness Test Equation and Calculator ...

The typical brinell hardness test uses a 10 millimeters (0.39 in) diameter steel ball as an indenter with a 3,000 kgf (29 kN; 6,600 lbf) force. For softer materials, a smaller force is used; for harder materials, a tungsten carbide ball is substituted for the steel ball. The indentation is measured and hardness calculated as:

This results in different pressure ratings for each type of PVC pipe. For example, a 4-inch-diameter SCH 80 PVC pipe has a pressure rating of 320 psi, compared to a 4-inch diameter SCH 40 PVC pipe which has a pressure rating of only 220 psi. As a more rigid pipe, the strength of a PVC pipe is a result of the pipe itself.
