While the water jet entered into the crack and mixed with the rock powder, the water wedge effect on fracture was formed which prompted the rock crack propagation and crushing. Meanwhile, the water jet washing the bottom and the hole wall carried the rock powder and debris out, which ensured the bit contacted rock fresh surface with each impact.

Crushed stone aggregates are produced by crushing quarried rock, then screening it to sizes appropriate for the intended use. Production of crushed stone has three stages: Primary crushing to break down the stone to a manageable size; secondary and tertiary crushing to render the rocks into sizes specific to their applications; and screening to separate the crushed stone for further processing

Model Setup. In this paper, emphasis is placed on the rock crushing process. Four basic assumptions are made: (1) the PDC bit is treated as being rigid; (2) an element is removed from the mesh if rock failure occurs; i.e., repeated fragmentation of cuttings is neglected; (3) the jet action of the mud is ignored, but the hydrostatic pressure is considered; and (4) the rock is assumed to be in

I have a 7" spacing on the grizzly. We run about 100 cubic yards of 1 1/2" crush through an hour, in a pit that has 98.5% less than 6" material. If you neck it down a bit, and make 3/4" crush, that takes a bit more time, as the openings need to be smaller and it''s got to do more crushing... lots of variables.
