## Surface theory crusher

Mar 11, 2016 Thus on the Rittinger theory that surface produced is proportional to energy applied the area of the diagram is a measure of the energy going into the crushing. (It should be distinctly understood that bearing- and gearing-friction losses should not be included in the energy-applied measured by the crushing-surface diagram, and that it is therefore impossible to compare the two

• Crushing Principle and Theory – Large Capacity double

1.Crusher area theory: Von Rittinger P R proposed the area theory in 1867. It is believed that the work done when an external force breaks an object will be converted into surface energy on the new surface area. Therefore, the energy consumption for crushing is proportional to the new surface area during crushing

• AMIT 135: Lesson 5 Crushing – Mining Mill Operator

The purpose of the primary crusher is to reduce the ROM ore to a size amenable for feeding the secondary crusher or the SAG mill grinding circuit. The ratio of reduction through a primary crusher can be up to about 8:1. Feed: ROM up to 1.5 m; Product: -300mm (for transport) to -200mm (for SAG mill) Feed Rate: 160 to 13,000 tph

• Crushing Theory | PDF | Mill (Grinding) | Applied And

Crushing Theory. Crushing Theory • When solid particles of feed material are being reduced in size, they are first distorted by straining and mechanical energy is stored in the solid in a similar manner to energy stored in a coil spring. • As more energy is applied, the material is distorted beyond their ultimate strength, thus causing them to rupture and thereby creating new surface
