Jaw crusher Uses and Applications:

1. The series of jaw crusher is mainly used for middle crushing and fine crushing of mid-hard ore and rocks in thesections of metallurgy, mining, chemical industry,cement, construction, ceramics together with refractories.

2.These crushers are most suitable to crush all kinds of soft and hard ore whose compressive strength is not higher than 300 Mpa. The maximum lumpiness of materials to be crushed should follow the technical data chart.

Operating principle of jaw crushers:

The motor drives the belt wheel, and makes movable jaw up and down by eccentric shaft. When the movable jaw rises, the angle between the fixed jaw and movable jaw gets larger, and the materials can be crushed to reach the crushing target. When the movable jaw is down, the angle between the fixed jaw and movable jaw becomes smaller. The movable jaw plate leaves the fixed jaw plate under the function of drawbar and spring. And then the crushed materials are discharged from the lower outlet of the crushing cavity.

The PC hammer stone crusher crushes by the collisions between high-speed hammer and material, which features in its simple structure, high reduction ration, high efficiency, ect.. The PC hammer crushers were developed for the both dry and wet crushing of brittle, medium-hard materials for the mining, cement, coal, metallurgic, construction material, road building, and Petroleum & Chemical industries.

Single stage hammer crusher can crush the feeded materials of graininess1100mm into less than 20mm for one time, so the traditional double stage or three stage crushing can be changed into one stage crushing so as simplify the process can be simplified flow, and the equipment investment saved consumption and other production expenses reduced. The hammer crusher falls into reversible and non-reversible hammer crushers. Reversible hammer crusher with reversible rotor used for fine crushing in general; non-reversible hammer crusher with non-reversible rotor used for intermediate crushing. Single stage hammer crusher is non-reversible. Ordinary hammer crusher is composed of frame, rotor, grate bar, impact plate and adjustment unit; single hammer crusher is composed of frame, rotor ,feeding roll, grate bar, hydraulic opening unit and foundation.
