Jaw Crusher Overview
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
Jaw crusher mainly consists of two jaw plates, one is fixed jaw plate, the other is movable jaw plate. In addition, there are flywheel, toggle plate whose application is to protect jaw plate, and tension rod used to adjust the size of discharging open to meet different jaw crusher need.
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 consists 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 jaw until it is small enough to pass through the gap at the bottom of the jaws.
Jaw Crusher Installation Instructions
- jaw crusher is installed by the factory, the user should be checked after the receipt of the jaw crusher machine and eliminate the various problems arising from transport, and then install it.
- rack installation, the vertical plane at the end of the level of tolerance of 0.5mm / m, the horizontal level degrees (measured on the spindle) Tolerance of 0.15 mm / m.
- comprehensive inspection before starting the jaw crusher machine. The fastening of the fixed parts, each part of the ubrication as well as V-belt tension level is to check the suitability of the like should be the focus.
- Check the overall circuit after cuting off jaw crusher switch, and a clear sign hanging switch.
