The closed-circuit Pegson 4242 SR horizontal impact crusher plant includes a screen and stockpiling conveyor with magnetic separator on one self-contained chassis. The unit is suitable for primary or secondary applications with concrete and asphalt rubble, demolition debris and aggregates — especially limestone with low to normal silica content.
The unit can be set up and operating within 10 minutes of arrival on site and can produce up to 396 tons (359 t) per hour, depending on the feed material and finished product size. One, two or three screened product sizes can be produced and stockpiled. Oversize material can be returned to the crusher inlet in closed circuit via an on-board return conveyor for guaranteed finished top size, according to the manufacturer.
The plant utilizes a heavy-duty, two-step vibrating grizzly feeder with built-in underscreen and folding side conveyor for either stockpiling waste material or a fourth product. Scalped material can be fed to the main product conveyor via a bypass chute to increase overall capacity. The double-deck, 11- by 5-ft. (3.3 by 1.5 m) vibrating screen has hydraulic drive and operates at 1,100 rpm. Dust-suppression sprays are standard. A special access system simplifies maintenance and screen mesh changing and PLC and plant controls are fitted onto the plant.
