Powerscreen’s Premiertrak 300 jaw crusher was developed with the option of a vibrating grizzly feeder or an independent hydraulically driven pre-screen, which improves fines removal and reduces chamber wear costs for the customer. Engine load controls both options to maintain throughput. To coincide with the independent pre-screen feature, an optional hydraulically folding extended side conveyor with a stockpile height of 10 ft., 2 in. was added to the machine to improve stockpile capacity. A bypass chute design incorporates a flap gate that allows operators to switch between using the side conveyor and sending material to the main belt without the need to fit a blanking mat on the bottom screen deck. The hopper design incorporates a complete hydraulic fold-and-lock system that removes the need for manual wedges.
