Abstract

Solid materials are fed into the crusher together with a pressurised liquid and led to a crushing passage for crushing large solid blocks into smaller solid particles. The crushed solid particles are discharged into a transportation pipe together with the pressurised liquid for piping out. The crusher comprises a cylindrical housing with inflow and outflow ports. and a cylindrical rotor eccentrically mounted inside housing to define the crushing passage. The passage becomes narrower toward the outflow port.
