Structure and Working Principle from HXJQ Jaw Crusher

Jaw Crusher is mainly used to crush kinds of mining stones primarily, and the largest compression resistance of the material is 320MPa. The jaw crusher is widely used in stone mining, metallurgy industry, building material, highway, railway, and chemical industry.it is one of the main types of primary crushers in a mine or ore crushing process plant and also is one of the most widely used crushing equipments in mining industry.Hongxingis a famous jaw crusher manufacturer in China, and sold crusher machines to all over the world. This series of jaw crusher can reach the crushing ratio of 4-6 and the shape of final product is even. Because it is primary crusher, Jaw crusher is designed for long life service with minimum maintenance for hard, tough, abrasive material and overload high capacity.
Jaw crusher structure are mainly frame, partiality axis, big pulley, flywheel, dynamic jaw, side guard board, elbow board, reposition spring, including cubits plates are also plays a role of insurance.
1. Simple structure, convenient maintenance, Stable performance and operation cost is low; Big crushing ratio,
2. Crushing cavity depth and no dead zone, improving the feeding capacity and output,
3. big crushing ratio and granularity,
4. Gasket type discharging mouth adjusting devices, big adjustable range, increased flexibility of the equipment;
5. Lubrication system is safe and reliable, convenient maintenance,
6. Simple structure, operation cost is low;
7. The saving-energy equipment: click energy-saving is 15% ~ 30%, system energy saving more than doubling,
8. Low noise, little dust.
Working Principle of jaw crusher
Primary jaw crusher is typically of the square opening design, and secondary jaw crusher is of the rectangular opening design. Jaw Crusher reduces large size rocks or ore by placing the rock into compression. A fixed jaw board, mounted in a 'V' alignment is the stationary breaking surface, while the movable jaw exerts force on the rock by forcing it against the stationary plate. The space at the bottom of the 'V' aligned jaw plates decide the crusher product size gap, or the size of the crushed product from the jaw crusher. The rock remains in the jaw until it is small enough to pass through the gap at the bottom of the jaws.

As the professional manufacturer of complete sets of mining machinery, such as Rotary dryers,Symons cone crusher, Henan Hongxing is always doing the best in products and service.
