1.Simple and robust design
Relying on many years of experience in the research and development of crushing equipment, combined with computer simulation and CAD optimisation design, the whole machine structure is simple and reasonable, and the framework is integrated. The structure has no unnecessary complex components, is stable and impact-resistant, and adapts to the high-intensity operation of the mine. The whole machine is stronger and more durable, and it is not easy to deform in long-term operation.
-
2.Elaborate detailed design
Use finite element stress analysis to optimise each structural detail, and strengthen the processing of key force parts; the structure of sealing, dustproof, shock absorption and consumable parts is refined and improved to effectively reduce the probability of wear and failure, operate more worry-free, and extend the service life of the whole machine.
-
3.High-quality processing and manufacturing
The core parts adopt precision CNC machining and professional heat treatment technology, with standardised production process, and the accessories have high accuracy and good interchangeability. Strict quality control from the factory, the assembly accuracy of the whole machine is high, the operation vibration is small, the stability is strong, and the quality is far higher than that of ordinary traditional crushers.
-
4.High strength and light weight
Through CAD design and finite element technology simulation analysis, the mechanical structure of the fuselage is optimised and upgraded. While greatly improving the structural strength of the whole machine and the impact resistance, the self-weight is reasonably streamlined, which is convenient for transportation and installation and on-site relocation, and also reduces the load-bearing input cost of the equipment foundation.
-
5.High production capacity and large crushing ratio
Optimise the deep cavity crushing cavity type and movement trajectory design, make the material crushing more complete, the unloading smooth and no blockage, and the single machine processing capacity is strong. The crushing ratio range is large, which can crush large pieces of materials to the ideal particle size at one time, simplify the crushing process, and greatly improve production efficiency.
-
6.Large feed particle size is allowed
The large-calibre feed port with the deep-deep crushing cavity structure design can directly accept large-sized raw stone and ore feed without pre-crushing in advance, adapt to the operation conditions of large material blocks, reduce the input of front-end equipment, and adapt to all kinds of large-scale mine quarry production lines.
-
7.High reliability and utilisation rate
The structural strength of the whole machine is sufficient, the core transmission parts are well selected, the technology is mature, and the operation failure rate is low. It can be stable at full load for a long time, with few downtimes and maintenance, and a high attendance rate for comprehensive equipment operations, which is suitable for year-round uninterrupted production.
-
8.The range of the discharge port can be adjusted with a large range and is easy to adjust.
The machine has a large adjustment span of the discharge port, and the finished product particle size is rich, which can meet the production needs of different specifications of stone. It adopts an optimised adjustment structure, which is simple to operate and does not require complicated disassembly and assembly. The adjustment is accurate and time-saving, and the production particle size can be easily switched.
Working Principle:
The processed materials in the jaw crusher are crushed between two hard surfaces. The movement of the moveable surface is the load of the jaw crusher. The effect of crushing is realised by the movement of the moving jaw with the fixed jaw and side lining plate in the broken cavity. The material block (i.e. rock or ore) is clamped, squeezed and broken between the moving jaw and the fixed jaw.
The quality and quantity of the processed materials depend on the interaction between the jaw crusher and the materials. The geometric shape of the broken cavity.The dynamic characteristics of the crusher and the nature of the treated material are the most important influencing factors.
The power from the driving motor is transmitted from the triangular transmission belt to one of the flywheels installed at the end of the eccentric shaft. The rotation of the eccentric axis and the movement of the elbow plate cause the moving jaw to produce an elliptical trajectory. When the distance between the two jaw plates narrows, the material entering the crushing cavity is squeezed and broken. When the moving jaw moves in the direction of leaving the fixed jaw, the material falls and discharges the crushing cavity.

Product Instructions for Use:
- Check that the CSS of the jaw crusher (tight edge discharge ore) is not less than the recommended value.
- Start the crusher and make it run under no-load for 2 hours, and check it as follows at the same time:
- Has the safety cover been installed in place?
- Is the rotary direction of the flywheel of the crusher correct?
- Whether there is abnormal noise.
- Whether the bearing is overheated.
- Correct the errors found during this period. After making sure that everything is normal, carefully send the materials into the crusher, and send the materials.When entering, it should be evenly distributed along the width of the feed port of the crusher. The feeding block should not be greater than the feeding port shown in the figure.
Product Maintenance:
1.In order to ensure the best performance of the jaw crusher, the feeding must be uniform. It is not allowed to enter large pieces of materials that exceed the size of the feeding port marked.
2.In the first month or 160 operating hours, check every day whether there is old grease sealed from the bearing maze.The circle is extruded. If not, grease the bearing will be filled with grease. Check the bearing temperature regularly. Check the tightening of all threaded joints.
3.Overloading the crusher should be avoided. The causes of overload are:
– Abnormal wear of the jaw plate (concave or “sled shape”).
– The excessive wear of the jaw plate or the bow shape of the jaw plate.
– The set value of the discharge port is too small.
– There are too many fine materials in the feed.
