P-7 | Technical specifications | Accessories The specified grinding ball sizes are application-dependent guidelines. It is not recommended to mix balls with different diameters.

P-7 | Technical specifications | Accessories Grinding balls with a diameter of 3 mm and smaller must be weighed. The above table shows the regulred weight per grinding bowl. The usable capacity depends on the type of material, The specified ball filling per bowl is the minimum Quantity; depending on the material behaviour, it may need to be increased, In exceptional cases, the Quantity of grinding balls can be reduced by up to 15 %. In order to achieve consistent grinding results In line with our recommendations, a longer grinding time Is necessary, which may result In Increased abrasion,
