Factors Controlling the Capacity of Rock Crushers

The calculation of crusher capacity is made in a somewhat similar manner. While the action ofrolls is simple, with few irregularities in operating conditions, in rock crushers the material advances intermittently, usually under the force of gravity alone, and is subjected to a variety of variable conditions.

TECHNICAL NOTES 5 CRUSHERS - Mineral Tech

The capacity of the crusher is determined by its size. The gape determines the maximum size of material that can be accepted. Maximum size that can be accepted into the crusher is approximately 80% of the gape. Jaw crushers are operated to produce a size reduction ratio between 4:1 and 9:1. Gyratory crushers can produce size reduction ratios over a somewhat larger range of 3:1 to 10:1. The ...

8. STRENGTH OF SOILS AND ROCKS

Rock strength has been found to be size dependent because of the cracks and fissures that are often present in the material. This is illustrated from the results of tests on three rock types in Fig. 8.2. The size dependancy is also found to exist for stiff fissured clays, as illustrated in Fig. 8.3 for London clay. Rocks with parallel arrangements of minerals or joints have been found to be ...
