Terex Pegson products included the 1412 Tracpactor impact crusher, 4242 SR impact crusher, 1300 Maxtrak cone crusher and 650 HA Premiertrak jaw crusher.
Powerscreen products included the Phoenix 1600 trommel, Finesmaster 200 sand recovery system, Chieftain 1800 3-deck and 2400 3-deck dry screen plants, and Powershredder 1800.
New Terex Pegson 1412 Trakpactor Impact Crusher
The 1412 track-mounted impactor plant features a Hazemag horizontal AP-PH 1214/Q primary impact crusher with hydraulic controls for more uniform products, plus the latest PLC CAN BUS control system to automatically regulate the feed to the crusher based on engine load. The machine is designed for crushing concrete and asphalt rubble, brick and medium-to-hard limestone.
The Hazemag impact crusher utilizes a hydraulic apron-locking mechanism with overload protection and automatic reset. This provides consistent product size with less oversize than conventional spring-loaded impactors, as well as additional protection against tramp metal.
In addition, the crusher opens and adjusts hydraulically and is fitted with a hydraulic tilting feed plate to improve blockage clearance.
The crusher feed opening is 32 by 54 in. and rotor size 48 by 54 in. with four reversible Martensitic steel blow bars. Ceramic blow bars are optional and the maximum feed size is 24 by 20 by 20 in. cube or 48 by 40 by 20 in. slab.
The standard hydraulic folding feed hopper has over-center struts and wedgelok system and a vibrating grizzly feeder with an underscreen 14 ft. by 54 in. The unit features an optional 13.5-in. wide hopper for shovel feed from the rear and a Caterpillar C12 438-hp diesel.
A modular 48 in. wide dual drive discharge conveyor raises and lowers hydraulically for maintenance and transport with ample clearance under the engine and a ripstop product belt. The swivel type dirt conveyor is 2 ft. wide and gives 7.9-ft. high stockpile with a two-way dirt chute.
Terex Pegson 1300 Maxtrak Cone Crusher
The 1300 Maxtrak crusher plant features the Automax “all-in-feed” cone design and is engineered for high tonnage, specification and flexibility, with low operating costs.
The self-contained plant design includes a belt feeder with integral hopper that can be fed with full level control from a conveyor, bucket loader or Terex Pegson Premiertrak.
The whole feeder/hopper assembly can be hydraulically lowered into the feed ring for transport or raised for re-metaling. The on-plant conveyor has a metal detector as standard and the crusher feed chute has a level probe and dust sprays.
The “all-in-feed” process with level control for choke feeding is designed to maximize throughput and production, optimize shape and minimize wear in secondary, tertiary and quaternary applications. The unit employs a simplified hydraulic system. and is powered by a Cat C12 with HFO heavy-duty clutch.
To maximize service life and product flow, minimize friction loss, eliminate “bowl bounce” and simplify maintenance, Automax crushers do not use plain bearings, bronze bushings or bronze bearing seat; there are no accumulators for tramp metal release and no spider bearing above the cone head.
Further, the 1300 Maxtrak requires fewer screens and conveyors; so overall plant cost is reduced. The hydraulic system can be adjusted quickly and easily, even while crushing and the unit has direct readout of crushing setting and manganese wear.
Terex Pegson 4242 SR Impact Crusher Plant
The closed-circuit Terex Pegson 4242 SR horizontal impact crusher plant includes a screen and stockpiling conveyor with a magnetic separator on one self-contained chassis.
The unit features a 428 fixed-hammer impactor, a 42 by 28 in. feed opening, a 42 in. rotor width and rotor diameter (over hammers) and 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 ten minutes of arrival on site and can produce up to 396 tons 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.
The plant utilizes a heavy-duty, two-step vibrating grizzly feeder with a 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 by-pass chute to increase overall capacity. The double-deck, 11 by 5 ft. vibrating screen has hydraulic drive and operates at 1,100 rpm. Dust-suppression sprays are standard and a special access system simplifies maintenance and screen mesh changing. PLC and plant controls are fitted onto the plant.
