How to Make a Ball Mill: 12 Steps (with Pictures)

Aug 10, 2020Ball mills are a special instrument used to break up hard solids into a fine powder. They are similar to rock tumblers in that the instrument is a rotating container filled with heavy balls to grind the substance into powder. Ceramic material, crystalline compounds, and even some metals can be ground up using a ball mill.

Size selection based on static load

Static load rating. The basic static load rating C 0 is defined in ISO 76 as the load that results in a certain value of contact stress at the centre of contact of the most heavily loaded rolling element/raceway. The contact stress values are: 4 600 MPa for self-aligning ball bearings. 4 200 MPa for all other ball bearings.
