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.
The SHH impact crusher is designed to be used as a primary crusher for soft and medium-hard stone. Kleemann also offers a wide range of models for this purpose. With feed openings ranging in size from 1270 mm x 1700 mm (SHH 12) to 2280 mm x 2700 mm (SHH 22) and maximum capacities up to 900 t/h, the right model can be found for every type of application.
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.
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 3020 mm x 1800 mm, feed capacities of up to 900 t/h can be achieved.
