Jaw crusher is a compression style rock crusher, useful in crushing the medium-hard to very hard material into a smaller particle size at primary crushing stage in the crushing circuit. Applications mining, quarry, construction waste recycling, aggregate making, etc. Materials Limestone, cobblestone, cobblestone, quartz, basalt, iron ore, granite, shale, sandstone, gypsum, and a variety of ores.
As one of the typically rock crushing equipments in the world, Jaw crusher is mainly used for primary and secondary crushing. Rock is dropped between two high manganese steel Jaw plates, one is fixed jaw plate, one is movable jaw plate. Movable jaw plate moves up and down via eccentric shaft, and then crush the rock between the two jaw plates into smaller size.

The movable jaw (Pitman) is attached to an eccentric shaft that causes it to move in a reciprocating motion. Rock enters the crushing chamber from the top and moves through the chamber, which gets narrower as it gets deeper, until it is caught between the two jaws, where it is squeezed until it fractures. Typical applications: Stone Crushing
eccentric shaft jaw crusher line. Jaw crusher can reach the crushing ratio of 4-6 and the shape of final product is even. It is widely applied to crush high hardness, mid hardness and soft rocks and ores such as slag, construction materials, marble, etc. The pressure resistance strength is under 200Mpa, that is, suitable for primary crush.
Generally speaking, jaw crusher spare parts are jaw plate, toggle plate, bearing and eccentric shaft. Eccentric shaft function. Jaw crusher eccentric shaft plays an quite important role in jaw crusher operating. The pitman is put in motion by the oscillation of an eccentric lobe on a shaft that goes through the pitman’s entire length.
Jul 18, 2015· The Gyratory Crusher is made up of six main components, Base, Main frame and concave liners, Drive assembly, Mantle, Spider arm assembly, Oil system. The base is the section of the crusher that provides an entry point for the drive assembly and oil system. It also provides support for the working surface of the main frame and liners.

The eccentric throw is one of the most important parameters in defining the job that your cone crusher does. The mantle in a cone crusher spins in conical pendulum motion. That means it doesn’t stay in the center of the chamber – it sweeps around moving closer and further away from the concave. This is what creates the crushing action. At a given point on the concave, material is
