Home > 4242 SR

The demand for a single crushing and screening unit capable of producing a controlled top size of finished product in closed circuit has led TEREX Pegson to design and manufacture the 4242SR plant containing a host of ‘user friendly' features.

The new 4242SR is based around the acclaimed 428 Trakpactor and comprises a complete crushing and screening and stockpiling unit built on one tracked chassis.

Suitable for primary and secondary applications in quarrying, contracting and recycling, the 4242SR has outstanding performance characteristics, with capacities up to 360 tonnes per hour. Up to four product sizes, depending on the set-up, can be produced and stockpiled. Alternatively, oversize material can be re-circulated back to the crusher via on-bound conveyor to give a guaranteed finishing top size.

The unit features a heavy duty vibrating grizzly feeder with two step grizzly, optional under- screen and side conveyor for stockpiling waste material or an additional product. Scalped material is fed onto the main product conveyor via a by-pass chute to increase overall capacity. An overband magnetic separator is available as an option for removal of re-bar and steel when used in recycling applications before the crushed material is fed onto a 3.3x1.5mm two deck screen for sizing. To reduce environmental impact, dust suppression sprays are also included as standard.

The whole plant can be set up to work within minutes of arrival on site and, at an approximate operating weight less than 45 tonnes, is easily transportable on a low bed trailer.
