Jaw crushers spare parts

Stone Jaw crushers

Jaw crushers are used in many industries: mining, PROCESSING, chemical, metallurgy, construction materials production. This equipment is the best choice for breaking the first and second stage for various metallic and nonmetallic materials with hardness up to 320 MPa.

Crushing of stone occurs through its crushing, bending, and sometimes wear two cheeks - crushing plates. One cheek is fixed, the second - swinging under the influence of the driving mechanism. Between the crushing plates is formed a wedge-shaped form of the workspace.

During the approach slabs crushability fraction material is crushed, during the withdrawal of mobile crushing cheek products pass through the discharge orifice - the minimum distance between the cheeks, depends on its size and the size of the crushed product. Depending on the obtained fractions equipment is large (up to 100-300 mm), medium (25-100 mm) and small (5-25 mm) fragmentation. According to the principle of jaw crusher, crushers vary with the simple, complex, and a combined movement of the moving plate.

Spare Parts of Jaw Crusher

Jaw crushing plates as the main spare parts of jaw crusher are made of a material with high wear resistance: made of cast steel with a manganese content of up to 10-16% (manganese). The surface of the plate has grooves, and they are located in the grinder so that the projection of one plate falls against other basins. Plates are usually symmetrical in the horizontal, which allows them to rearrange the lower, faster moving parts, up.

Armour, which is used in the cash jaw crusher usually, applies ZGMn13. He has such features: under the influence of load shocks, it is characterized by a surface hardened and durability, while its initial ductility of the metal inner preserved. Therefore ZGMn13 is the most common wear-resistant material in the crusher.

The main features of the usual high-manganese steel are as follows: during the use of the material deformation easily arise. To develop abroad, we have cooperated with the research institution to make armor-doped iron, whose longevity has increased by approximately 10% -40% longer than conventional high-manganese steel, and while using the deformation of the material will be almost no.

Jaw crushing plate belongs to the wear spare parts. They restore the surfacing hard alloys. The company “SBM” supplies spare parts for jaw crushers and other equipment imported and domestically produced.
