contact us· In this study, the fractal fragmentation theory is used to describe the PSD of rock after crushing. The new surface theory is adopted to characterize the rock firmness; the firmness is directly proportional to the surface energy consumption (Bond 1955; Carpinteri et al. 2004) bining these two theories, a new index, f s, is proposed.Through a large number of experiments, the effects of the ...

contact usA Jaw Crusher reduces large size rocks or ore by placing the rock into compression. A fixed jaw, mounted in a "V" alignment is the stationary breaking surface, while the movable jaw exerts force on the rock by forcing it against the stationary plate. The space at the bottom of the "V" aligned jaw plates is the crusher product size gap, or
contact us· Rock crusher. Material is reduced by crushers and grinders by fracturing, which takes place when the material is put under stress by the moving parts of the crushing or grinding equipment. Forces applied during the process may be compressive, shear or impact. The material fractures when the internal strain levels reach a critical level.
