How to Choose High-Performance Jaw Crusher?
With the continuous development of industry, jaw crushers are widely used in mining, building materials, railways, highways, smelting, and chemical industries relying on the advantages of large crushing ratio, uniform product size, and high production capacity. Choosing a suitable rock jaw crusher can improve the production efficiency, finished product effect, and economic benefits, so how to choose a high-performance jaw rock crusher?
1. Frame design
Due to the limitation of casting technology, the design of an integral casting frame makes the casting easy to form a large number of micro pores in the casting process, thus reducing the overall performance of the frame. Relatively speaking, the installation of split assembly frame type jaw crusher plant is lighter, more reliable, and more durable.
2.Jaw plate design
The three-stage combined jaw plate is not only superior to the integral jaw plate in design, but also has lower operation and maintenance cost. Because the combination, installation, and disassembly of the three-stage combined jaw plate are very convenient, and when the bottom end of the jaw plate is severely worn, it can also adjust the position with the upper jaw plate to continue to use and save the cost.
3. Shape and material of guard board
Compared with the ordinary guard board, the tooth guard board can increase the effective length of the jaw plate and increase the output. In addition, due to the more contact between the guard plate and the material, in order to prolong the service life, the wear-resistant high manganese steel material is generally selected.
4. Fixing method of bearing seat
The bearing seat of some stone jaw crushers is welded to the frame, and some adopt an integral cast steel structure and are connected with the frame by bolts. The latter ensures the complete matching between the bearing seat and the crushing frame and effectively enhances the radial strength of the bearing seat.
5. Adjustment method
Adding gasket is a common adjustment method of traditional jaw stone crusher, but compared with gasket adjustment, the improved hydraulic wedge adjustment method is more convenient, safe and efficient. The staff only needs to operate the control lever connected to the hydraulic valve to adjust the height of the discharge port.
6.Shape of crushing cavity
The crushing cavity of the fine jaw crusher can be roughly divided into the linear type and curve type. When the linear crushing cavity is working, a trapezoidal section appears on the surface of the cavity wall. This section is continuously reduced during the work process of the jaw crushing, which affects the continuous increase of the swing of the movable jaw during the work process and easily causes the phenomenon of blocking the discharge port. The curve crushing cavity uses the incremental state to increase the contact surface between the dynamic and static jaw and the crushing chamber when working, which can avoid the phenomenon of material blocking in the jaw crushing machine to a certain extent.
7. Lubrication method
Old-fashioned prmary jaw crushers usually adopt manual lubrication and the operator uses an oil pot or oil gun to fill oil at the lubrication point. Compared with manual lubrication, most modern advanced jaw crushers adopt centralized hydraulic lubrication, which has greatly improved the operability and technology.
8. After-sales service
The static jaw crusher will have some failures more or less during the production process. Manufacturers with high-quality after-sales service can help users solve the problem as soon as possible and put it into production smoothly.
