を防止することができなかった。"Prior Art" In the conventional method of preventing clogging of vibrating screen mesh, a grid is provided under the screen of the vibrating screen, and large and small natural rubber balls are placed in the grid.
Up to 6 pieces of them were accommodated and clogging was prevented by tapping the mesh from the lower part by utilizing the centrifugal force associated with the centrifugal movement of the vibrating screener and the mutual repulsive force of the large and small balls. According to this method, the vibrating screener is processed from the beginning of the design, and therefore, when it is clogged due to changes in usage conditions, it becomes difficult to use the vibrating screener. In this case, the upper surface of the sieve mesh was tapped with a chain or a tapping ball placed above the sieve mesh to prevent clogging (Japanese Patent Publication No. 56-11515, Japanese Utility Model Publication No. 56-4454).
issue). However, if the amount of the material charged on the sieve mesh is too large, the chain or tapping ball will not climb on the sieve mesh and prevent clogging.
