Mobile jaw crushers. The crushing plants in the MOBICAT series are used for pre-crushing of almost all natural stone and for recycling. The output of the MOBICAT crushing plants, however, is not determined by the jaw crusher alone, but rather the optimised interaction all components plays a decisive role. The focus is also increasingly on cost ...
functioning Jaw crusher. Most of these components are discussed below. Moveable jaw stock The moveable jaw stock is the main moving part in a jaw crusher. It forms the moving side of the jaw, while the stationary or fixed jaw forms the other. It achieves its movement through the eccentric movement of the crusher main shaft. It is the back and
Sep 02, 2019 Jaw crusher units with extra-long, articulated crusher jaws prevent coarse material from blocking while moving all mounting elements of the crusher jaw from the wear area. A more even material flow may be affected if the transfer from the prescreen or the feeder trough is designed so material simply tilts into the crushing jaw.
Jaw crushers are an excellent primary crusher when used to prepare rock for subsequent processing stages. Cone and gyratory crusher. These are also compression-type machines that crush material between a moving and a stationary piece of steel. The setting between the two pieces controls the output.
Coarse crushing jaw crusher is commonly employed for primary crushing. Its model is determined by the maximum particle size and the output capacity you require. Secondary crushing the type of the crusher machine is determined by the hardness of the material. For soft and brittle materials like limestone, impact crusher is typically used.
In the Jaw crushers, the material particles are broken down by the compressive and shear strains between the fixed and moving jaws. The grain size of the crushed material is determined by the gap between the jaws in the lower part the discharge slot and the physical properties of the material.
Jaw crushers. Jaw crushers are used for coarse grinding brittle, medium-hard to hard materials up to a Mohs hardness of approx. 8.5. Here reduction ratios of up to 1100 are possible depending on the actual model concerned. The crushing jaws are executed by us in two versions In a laboratory model with integrated control system, feeding ...
