Abstract:
A crushing and particle sizing apparatus for granular material that sizes particles of wet or dry material, said apparatus comprising:a casing including a substantially hollow conical member, a material inlet port and a discharge port; a conical rotation body and a disc-like rotation body provided within said casing, a gap between the conical rotation body and the substantially hollow conical member defining a particle retention region that narrows in the direction of the disc-like rotation body; and an opposing face portion providing within said casing, opposed to the rotation bodies and spaced from the rotation bodies, a gap region being defined between said disc-like rotation body and said opposing face portion, the gap region including a face section and a line section; wherein particles too large to pass through said gap region are brought into contact with said opposing face portion at the face section and line section in association with rotation of said rotation bodies and are crushed between said rotation bodies and said opposing face portion to such an extent that the particles can pass through said gap region and be discharged from the discharge port.
