Grinding apparatus wherein a cylindrical or polygonal tank of any material and a proper length lined on the inside surface with any of such materials as a rubber, synthetic resin, brush, fiber and paper pulp. The tank is held at one end and is rotated at the other in a universal joint end. Thus, grinding agents and materials to be ground are put into the tank at the held end. A centrifugal motion is generated on the inner peripheral surface of the tank and the materials will flow to the other end and be ground while rotating spirally due to the centrifugal force on the inner peripheral surface of the tank while in contact with grinding agents. Further, a grinding apparatus wherein a cylindrical or polygonal tank of any material and a proper length, as required, lined on the inside surface with any of such materials as a rubber, synthetic resin, brush, fiber and paper pulp is held at one end and is held at the other end with an arm made to make any proper circular motion with crank arms or the like.
