The nip angle is affected by the distance between the rolls The nip angle is defined as the angle that is tangent to the roll surface at the points of contact between the rolls and the particle It depends on the surface characteristics of the rolls Usually the nip angle is between 20 and 30 but in some large roll crushers it is up to 40

A ball mill a type of grinder is a cylindrical device used in grinding (or mixing) materials like ores chemicals ceramic raw materials and paints Ball mills rotate around a horizontal axis partially filled with the material to be ground plus the grinding medium Different materials are used as media including ceramic balls flint pebbles and stainless steel balls

the mill is used primarily to lift the load (medium and charge) Additional power is required to keep the mill rotating 8 1 3 Power drawn by ball semi-autogenous and autogenous mills A simplified picture of the mill load is shown in Figure 8 3 Ad this can be used to establish the essential features of a model for mill
