Jaw Crusher - The primary crusher
Jaw crusher is a widely used crusher machine in mining industry. The crusher feed size is up to 1000-1200mm.For primary crusher it is the best choise!
Jaw crusher
Jaw Crusher is one of the main types of primary crushers in a mine or ore processing plant and also is one of the most widely used crushing equipment in mining industry. 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 Parts
- two jaw plates,one is fixed jaw plate,the other is movable jaw plate.
- flywheel,toggle plate whose application is to protect jaw plate.
- ension rod used to adjust the size of discharging open.
Jaw Crusher Application
Jaw Crusher can be used in mining, metallurgical industry, construction, road and railway building, conversancy, chemistry, etc.In these industryes Jaw crusher is widely applied to crush high hardness, mid hardness and soft rocks and ores such as slags, construction materials, marble, etc.,whose pressure resistance strength is under 200Mpa.
Jaw Crusher Main Features and Benefits
- flexible capacity and high reliability
- Simple structure and easy maintenance,jaw crusher mainly consist of two jaws
- over-loading protection, jaw crusher has toggle plate to protect it.
- stable performance ,low operating cost.
- High crushing ratio which can reach 4-6., also high resistance to friction, abrasion and compression with longer operating life span.
Jaw Crusher working principle
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 jaws until it is small enough to pass through the gap at the bottom of the jaws.
Jaw Crusher inspection and maintenance
- Check bearing temperature,bearing temperature is no more than 60℃. You can use the thermometer measurements.
- Check lubrication system and water cooling system of jaw crusher, whether there is oil spills, leakage phenomenon. Check noise and vibration of pump.
- Check the wear of jaw crusher machine parts and whether the connection is loose.
- Regularly changed oiland cleaning lubrication filter.
