PROBLEM TO BE SOLVED: To provide a medium circulation type crusher permitting treatment of a high-viscosity slurry, capable controlling the tendency of the medium being pressed toward the outlet side and eliminating the possibilities of rising of the inside pressure of the vessel and heat generation. SOLUTION: On the rotor of a stirring member, grooves having a width measured in the direction of the rotor axis twice the diameter of the stationary pin are formed on the cylindrical surface opposing the stationary pin protruding from the vessel in respective directions of the axis of the stationary pin. The grooves cause the crushing medium to move and circulate in the radial outward direction owing to centrifugal force received from the side wall of the grooves. The momentum of the crushing medium increases even in the region in the vicinity of the stationary pin usually serving as a static region, resulting in an increase of the amount of the slurry transported through transferring. Since the cross-section allowing the slurry to pass through increases, the passing resistance of the slurry decreases, the pressure loss in the vicinity of the stationary pin lowers, and the crushed amount increases, permitting treatment of a high-viscosity slurry.
