Roll Crushers

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

Ball mill

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

How the Tool Helix Affects

Cutting forces on an end mill have axial and radial components that affect how it functions The radial component often leads to vibrations and the axial component affects the force of the mill against the holder These components are varied by changing the helix angle on a tool and different angles are better for different []
