APPARATUS FOR PREVENTING CONE CRUSHER OVERLOAD AND CONE CRUSHER INCLUDING THE SAME

摘要

eccentrically rotating crushing cone to have konbu and crushing konbu state over a predetermined distance spaced locations crushing operations having a crushed and placed on the mantle, by crushing cone spacing is variable by rotating the eccentric portion crushed between the object and the crushing mantle konbu crushing unit is provided with an overload protection device for the cone crusher which is crushed. The apparatus, by using the hydraulic pressure received by the oil to the inside of the plurality of cylinders arranged to release the downward pressure on at least the crushing mantle portions, each connected to at least one of the release cylinder is connected to at least one of the plurality of Released cylinder at least a plurality of buffer portion provided that the oil is flowing to provide a lower pressure in a cylinder associated with the release of a predetermined reference pressure than the pressure applied to the oil to provide a lower pressure in the mantle is disrupted due to a difficult crushing debris Among a plurality of Released cylinder when a predetermined reference pressure than the pressure acting on the oil portion of the release cylinder to provide a downward pressure on the discharged areas of the plurality of buffer portions connected to the buffer portion, and a control unit for controlling the plurality of buffer , downward pressure of the release cylinder is characterized in that the possible rise in the crushing area by removing those parts of the mantle.
