Rock Abrasion Crushers - 911 Metallurgist

23/10/2016  In crushing, the abrasion occurs chiefly as direct rubbing under the interposition of an abrasive in the form of free particles, either of the metal or the rock, chiefly the latter. It becomes complicated by variations of physical properties, dimensions and distribution of the free abrasive agent on the wearing surface of the metal. The principal factor affecting durability is the surface-pressure exerted. In certain cases this may be favourable to the metal,

Factors Affecting the Crushing Efficiency of the Crusher ...

If the moisture content of raw material is too high, it will also reduce the crushing efficiency of a rock crusher. This is because during the crushing process, too wet raw materials will adhere to the crushing cavity and other parts, reducing the volume of the crushing cavity and the crushing efficiency.
