Jaw crusher

Operating principle

Jaw crushers operate according to the principle of pressure crushing. The crushing material is crushed in the wedge-shaped pit between the fixed crusher jaw and the crusher jaw articulated on an eccentric shaft. The material is crushed by the elliptic course of movement and transported downwards. This occurs until the material is smaller than the set crushing size.

Jaw crusher - STR type

Kleemann offers a range of jaw crushers for different feed and grain sizes and performance capacity. The single toggle jaw crusher of the STR type has openings up to 1600 x 2100 mm in size. The maximum feed capacity is up to 1500 t/h.

Cone crusher

Operating principle

With these crushers the crushing is effected by pressure crushing in an opening and closing crushing gap between the bowl liner and mantle. The opening and closing are effected simultaneously on the opposite sides of the crushing chamber.

With the KX cone crusher the crusher axle is pressed into the main frame. The mantle support is mounted on an eccentric hydraulic drive. The gap between the mantle and bowl liner is opened continuously with the rotation of the hydraulic drive. The grain size to be produced is changed by lifting or lowering the bowl liner.

Impact crusher

Operating principle

In comparison to pressure crushing, the principle used here is impact crushing. In this process, the crushed material is picked up by a fast moving rotor, greatly accelerated and smashed against an impact plate ("impact toggle"). From there, it falls back within range of the rotor. The crushed material is broken again and again until it can pass through the gap between the rotor and impact toggle.

Impact crusher - SNH type

The SNH impact crushers are the so-called secondary impact crushers and are mainly used in the second crushing stage. They are suitable for medium-hard to hard stone and gravel for feed sizes up to 250 mm. Mineral mixtures and high quality chippings are produced here from the pre-crushed material. SNH impact crushers also achieve excellent results as the primary crusher for river gravel.

Impact crusher - SHB type

The SHB impact crushers are also secondary impact crushers. They are distinguished by their particularly robust construction and are ideal for crushing natural stone, as well as concrete, rubble and asphalt. Thanks to feed openings of up to 1660 mm x 1000 mm, feed capacities of up to 700 t/h can be achieved.
