subject: Jaw Crusher Working Principle And Characteristics [print this page] Jaw crusher is used as the primary crusher to the medium size crushing of various ores and large-size materials and it is widely used in stone mining, metallurgy industry, building material, highway, railway, and chemical industry. It can crush high hardness, mid hardness and soft rocks and ores.
Jaw crusher structure are mainly frame, partiality axis, big pulley, flywheel, movable jaw plate, fixed jaw plate,side guard board, elbow board, reposition spring, including cubits plates are also plays a role of insurance.
Jaw Crusher working principle:
The motor transmits power through belt, drives the movable jaw plate to do periodic motion towards the fixed jaw plate by the eccentric shaft. The angle between toggle plate and movable jaw plate increases when movable jaw moves . So the movable jaw moves towards the fixed jaw. The stuff will be crushed in this process. The angle between toggle plate and movable jaw decreases when movable jaw moves down, the moving jaw moves leaves fixed jaw by pulling rod and spring, the final crushed stuff will be discharged from the outlet.
Jaw crusher characteristics:
The crushing chamber is deep without dead zones, thus improving the feeding capacity and output;
Big crushing ratio, and uniform particle size;
Reliable and convenient gasket type adjustment device of the discharge port, and wide adjustment range increase the flexibility of the equipment;
Safe and reliable lubrication system, convenient replacement of spare parts, and easy maintenance, etc.;
Simple structure, reliable function, and low operation costs;
Energy-saving: A single machine can save energy by 15%-30%, and the whole system can save energy by more than one time;
The adjustment range for the discharge port is wide so as to meet different customers' requirements;
