Portable Crusher Manufacturer

The Crawler Jaw Crusher (also called tracked jaw crusher or pedrail jaw crusher)was designed by ourselves, utilizing the very latest European technology, including finite element techniques to minimize stress levels within the frame itself. Kefid has used all their experience gained over the last 23 years in manufacturing crushers, to produce their most modern and efficient crushers, which is targeted at the Recycling and Aggregate Contractor segment of the market.

The Crawler Jaw Crusher is mounted directly onto chassis on 4 pins,which is fully driven by hydraulic force and moves by chassis track. This has the added benefit of eliminating stress on the chassis. The crusher is welded in low stress areas, thus giving longer life.

The feeder is equipped with a grizzly section located at the discharge end for removal of fines. This feature allows the passage of fine material direct to the discharge conveyors, so that it does not pass through the Jaw Crusher feed opening. This design makes possible a high production capacity by avoiding the accumulation of fine material (sometimes mud or clay) at the bottom end of the crushing chamber. The layer of fine material separated by the grizzly feeder is fed on to the main conveyor belt before the drop point from the jaw crusher and reduces the impact from the larger stones on the belt, beneath the Jaw Crusher. The fine material and the crushed product are transported on the main conveyor.

As an option, a separate natural fines belt conveyor can take out the natural fines.
