Abstract

1. A jet crusher in which the granular and powdered material is continuously or discontinuously fed in an enclosure around which are disposed several nozzles (2, 3), arranged at differents levels and fed with a pressurized fluid insuring centripetal jets appreciably horizontal within the material in order to cause crushing areas by the impacts between the grains (attrition) and raise the most fine particles which are then permanently extracted by the top, whereas the bigger particles, because insufficiently crushed, laterally fall back into the material to be crushed, the big particles carry along with the fines being fed again in the crushing enclosure after sorting in the separator, characterized by the fact that the nozzles (2, 3) are fed with controlled pulses of gas by at least a distributor (34, 40) feeding alternately the different nozzles (2, 3).
