Abstract
An apron return assembly having a pump that is adapted to convey a fluid, an apron actuator having an apron actuator cap side and an apron actuator rod side and being in fluid communication with the pump, an accumulator that is in fluid communication with the apron actuator cap side, a reservoir that is in fluid communication with the apron actuator, and a tension rod having a frame end and an apron end. In the preferred apron return assembly, the apron actuator and the tension rod are adapted to move the apron between a closed position and an open position. A method for moving the apron from the open position to the closed position.
Claims20
An apron return assembly for a rock crusher have an apron and a rotor, said apron return assembly comprising:
- (a) a pump, said pump be adapted to convey a fluid;
- (b) an apron actuator, said apron actuator having an apron actuator cap side and an apron actuator rod side and being in fluid communication with the pump;
- (c) an accumulator, said accumulator being in fluid communication with the apron actuator cap side;
- (d) a reservoir, said reservoir being in fluid communication with the apron actuator;
- (e) a tension rod, said tension rod having a frame end and an apron end;
- wherein the apron actuator and the tension rod are adapted to move the apron between a closed position and an open position.
An apron return assembly for a rock crusher have an apron and a rotor, said apron return assembly comprising:
- (a) a pump, said pump be adapted to convey a fluid;
- (b) an apron actuator, said apron actuator having an apron actuator cap side with a solenoid valve, an apron actuator rod side, and a relief valve and being in fluid communication with the pump;
- (c) an accumulator, said accumulator having a counterbalance valve and being in fluid communication with the apron actuator cap side;
- (d) a reservoir, said reservoir being in fluid communication with the apron actuator;
- (e) a tension rod, said tension rod having a frame end and an apron end;
- wherein the apron actuator and the tension rod are adapted to move the apron between a closed position and an open position;
- wherein the counterbalance valve is in an open condition during normal crushing operation;
- wherein the apron is maintained in the closed position when a predetermined apron actuator pressure in the apron actuator cap side is not exceeded;
- wherein the apron is moved from the closed position to the open position when the predetermined apron actuator pressure in the apron actuator cap side is exceeded;
- and wherein the apron is moved from the open position to the closed position when the predetermined apron actuator pressure in the apron actuator cap side is not exceeded.
A method for returning an apron to a closed position, said method comprising:
- (a) providing an apron return assembly, said apron return assembly comprising:
- (i) a pump, said pump be adapted to convey a fluid;
- (ii) an apron actuator, said apron actuator having an apron actuator cap side and an apron actuator rod side and being in fluid communication with the pump;
- (iii) an accumulator, said accumulator being in fluid communication with the apron actuator cap side;
- (iv) a reservoir, said reservoir being in fluid communication with the apron actuator;
- (v) a tension rod, said tension rod having a frame end and an apron end;
- wherein the apron actuator and the tension rod are adapted to move the apron between a closed position and an open position;
- (b) moving the apron from the open position to the closed position.
