Title: Roll crusher
Inventor: SHIGEFUJI YOSHIHIRO
IPC: B02C4/02
Filed: 1989-02-07
Abstract: PURPOSE:To obtain pulverized powdery material by forcedly rotating a crushing roll around a rotary axial center and pushing it on the other crushing roll and also freely rotating the other crushing roll around a rotary axial center and freely movably supporting this roll so as to be moved back and forth to the direction of the rotary shaft. CONSTITUTION:Brittle material 8 contained in a supply shute 7 falls toward the lower gap S and is pressed on the outer circumferential face of the driven crushing roll 2 because a driving crushing roll 1 rotated by a motor 6 is pushed by the hydraulic cylinders 3. Since the driven roll 2 is rotated, shearing force directed to the circumferential directions of both crushing rolls 1, 2 is allowed to act on the brittle material 8 in the interval of the gap S. On the other hand, since the driven crushing roll is moved back and forth to the direction of the rotary shaft by a hydraulic cylinder 4, shearing force directed to the longitudinal directions of both crushing rolls 1, 2 is simultaneously allowed to act on the brittle material 8. This brittle material 8 being compressed and crushed is effectively disintegrated by synergistic effect of these shearing forces and made pulverized material.
