Jaw Crusher Introduction
Jaw crusher is an early crushing equipment used for crushing various ores and bulk materials with a compressive strength of 147-245MPa.
Because of its simple structure, high degree of intelligence, reliable operation, easy maintenance and repair, and relatively low production and construction costs, it is still widely used in metallurgy, chemical industry, building materials, transportation and other industrial sectors.
Continuous innovation and upgrading, there are new German version of jaw crusher, CJ European version of jaw crusher and other series launched, welcome to continue to pay attention to rolls machine.
jaw crusher performance characteristics
1. Integral steel frame base: The flywheel design is used to effectively reduce vibration and make the machine run more smoothly. At the same time, the integrated structure of the motor base and the host makes the installation easier, saves space and reduces the cost of use.
2. Higher crushing efficiency: The crushing cavity is deep and there is no dead zone, which improves the feeding capacity and output. The crushing ratio is large, the particle size of the finished product is uniform, and the particle shape is good.
3. The quality of the movable jaw is reliable: the jaw crusher is jointly designed and advanced in technology based on 40 years of experience in the crushing industry. It is composed of cast steel parts, which is more firm and reliable.
4. Convenient discharge adjustment: The crushing cavity adopts a symmetrical "V" shape structure, so that the actual feeding port width is consistent with the nominal feeding port width, which is more conducive to quick and convenient adjustment of the discharge port. The equipment is also equipped with a wedge block row Feed opening adjustment device is simpler, safer and faster.
The working principle of jaw crusher
jaw crusher structure
The jaw crusher is mainly composed of a frame, an eccentric shaft, a large pulley, a flywheel, a movable jaw, a side guard plate, a toggle plate, a toggle plate back seat, a clearance adjustment screw, a return spring, a fixed jaw plate, a movable jaw plate, a motor, etc.
Among them, the toggle plate is a precisely calculated welding part, which is not only a transmission component, but also an insurance part of the crusher. When the unbreakable material falls into the crusher and the machine exceeds the usual load, the toggle plate will be broken immediately, and the crusher will stop working, thus avoiding the damage of the whole machine.
Jaw Crusher Frame
The frame of jaw crusher is divided into two types: welding type and assembled type.
The welding type adopts the welding method of large arc transition fillet and low stress area, which greatly reduces the stress concentration, ensures the equal strength of the frame in all directions, and has the characteristics of impact resistance, uniform force and low failure rate.
The assembled type adopts a modular, non-welded frame structure design, which has high strength and reliability. At the same time, the whole-machine assembled design is more convenient for transportation and installation. It is especially suitable for installation in underground mines, high-altitude mines and other narrow and difficult places for transportation.
The frame of the JC series jaw crusher is divided into two types: welding type and assembled type: the small and medium-sized specifications generally adopt the welded type, and the large-scale specifications generally adopt the assembled type.
2. Toggle plate

Brackets are precisely calculated weldments. It is not only a transmission component, but also an insurance part of the crusher. When the unbreakable material falls into the crusher and the machine exceeds the usual load, the toggle plate will be broken immediately, and the crusher will stop working, thereby avoiding damage to the entire machine. The toggle plate and toggle plate pad are in rolling contact, and there is little friction in normal use, just apply a layer of grease on the contact surface.
3. Adjustment parts
jaw crusher adjustment parts
The adjustment part is a mechanism for adjusting the size of the discharge opening and compensating for the wear between the jaw plate, the toggle plate and the toggle plate pad.
Assembly process of adjusting parts: toggle plate pads are fixed on the adjusting seat by angle steel and bolts, and the adjusting washer is placed between the adjusting seat and the lower frame.
V-shaped crushing cavity: The V-shaped cavity structure makes it easier to discharge materials, and it is not easy to block materials, and it is not easy to jump materials, which improves the crushing capacity and increases the crushing efficiency.
Discharge port adjustment: The wedge is used to adjust the discharge port, which can achieve stepless speed regulation. Compared with shim adjustment, it is simpler, safer and faster. It does not need to stop, which greatly reduces the labor intensity and downtime of workers and improves efficiency.
Reliable quality: The non-welded frame is adopted, which overcomes the shortage of stress concentration of the welded frame, and is more durable; the integral bearing seat design increases the radial strength and bearing capacity of the bearing seat, and cooperates with an effective labyrinth seal, Greatly prolongs the service life of the bearing.
Reasonable structure: integrated motor structure, the motor is mounted on the frame, making the installation easier and reducing the installation space.

Pebble crushing takes into account the investment cost of the crushing project, but also the production cost of the production line. Its production line has the characteristics of simple structure, low energy consumption and large production capacity. Since the pebbles are being crushed, the wear and tear of the equipment wear parts is very high. Therefore, in the design of the crushing process, the crushing equipment with the concept of "more crushing and less grinding" and the lamination principle should be selected as much as possible to reduce the loss of wear-resistant parts, and exclude some traditional crushing equipment based on the principles of grinding and beating. Typical sand making equipment configuration is jaw crusher, cone machine, cone sand making machine, vibrating screen, spiral sand washing machine (bucket wheel sand washing machine), fine sand recovery device and other process configurations.
Basalt is the best material among the stones used for repairing roads, railways and airport runways. It has strong compressive resistance, low crush value, strong corrosion resistance, and asphalt adhesion. Basalt has wear resistance, low draft, It has the advantages of poor electrical conductivity, strong compressive resistance, low crush value, strong corrosion resistance and asphalt adhesion, and has been recognized by the international community. It is the best cornerstone for the development of railway transportation and road transportation.
Granite has high hardness and durability, and is an ideal material for the production of wall tiles and floor coverings. Granite crushed can be widely used in water conservancy and hydropower, highway, railway, chemical, building materials and other industries. Granite stone has high hardness and moderate compressive strength, and is a good building stone. Due to the high content of needle flakes and internal cracks in granite crushed stone, if it is processed into stone for building specifications, it must be crushed with three or more grades, or be shaped with a cone sand making machine to ensure the stone. particle size (less needle-like, flake-like). According to the characteristics of granite material, our company specially designed a set of reasonable crushing process. While considering the investment cost of the crushing project, the production cost of the production line is also considered. Its production line has the characteristics of simple structure, low energy consumption and large production capacity.
The typical crushing equipment configuration of limestone is jaw crusher, cone crusher, vibrating screen and other process configurations. The production line adopts two-stage crushing, which fully considers the matching of technical parameters between the various levels of crushing, which not only ensures the maximum grain quality of the product, but also meets the requirements of the best crushing ratio of various types of crushers. The finished stone fully meets the requirements of customers and local environmental protection. The production line adopts two-stage crushing, which fully considers the matching of technical parameters between the various levels of crushing, which not only ensures the maximum grain quality of the product, but also meets the requirements of the best crushing ratio of various types of crushers. The finished stone fully meets the requirements of ordinary building stone.
