·For gyratory crusher the outer circle represents the stationary bowl covered by the concave and the inner circle represents the main shaft covered by the mantle The main shaft rests in the eccentric bushing at the base of the crusher As the eccentric rotates the base of the main shaft moves in a circular path around the crusher centerline
·alterations in the relative positions of stationary and swing jaws with respect to the vertical; the introduction of curved non choking jaw plates The original Blake crusher was designed with a vertical stationary jaw Probably the first departure from this arrangement was an 84 X 66″ crusher built in 1914
·The SUPERIOR® gyratory crusher is a compressive style crusher for primary stage applications Its steep crushing chamber and long crushing surfaces provide exceptionally high capacity and long liner life A gyratory crusher consists of a concave sur face and a conical head; both surfaces are typically lined with manganese steel The top
• Larger particles are crushing at a higher vertical position that produces lower torque; The power and torque have less temporal variation in comparison to the nonuniform case where the crushing power changes from 0 to 2000 kW; avoiding these cycles of load and unload will reduce the fatigue in the machine elements of the gyratory crusher
How Do Gyratory Crushers work The gyratory crusher is a heavy machine consisting of an iron or steel frame with an actuating mechanism and a cone shaped chamber lined with wear resisting plates A steady rest called a spider supports the upper part of the machine The main shaft passes through the eccentric journal at its lower end which
·A gyratory roller crusher in which the rollers have a corrugated profile and at least one of the rollers is eccentrically mounted to give a relative gyratory motion to the rollers The arrangement in the gyratory roller crusher results in additional breakage mechanisms for the comminution of a very wide range of feed material vastly improved crushing ratios and
·Gyratory crusher is a crushing equipment that uses the gyratory motion of the crushing cone in the conical cavity inside the shell to extrude bend and impact materials for the purpose of coarse crushing of the materials of various hardness If the hydraulic oil volume below the plunger is changed the crushing cone position can be moved
·The gyratory crusher is one of the most important mineral processing assets in the comminution circuit and its production performance directly impacts the circuit throughput
