Brief Description of Jaw Crusher
The jaw crusher is suitable for crushing hard materials (compressive strength < 250Mpa), such as iron ore, slag, phosphate ore, silicon ore, copper ore, limestone, quartz, ceramics and solid materials with the same hardness, such as coarse crushing of large blocks in rock ore processing plant, coarse crushing of large blocks in stone crushing plants, and coarse crushing of large blocks of limestone in cement plants. It has the characteristics of large crushing ratio, low maintenance cost, low power consumption and reliable performance. It can be widely used in mining, aggregate crushing plant, building materials, metallurgy, ceramics and other industries.
Working Principle of Jaw Crusher
The working mode of the jaw crusher is the curved extrusion type. Its working principle is: the motor drives V-belt and pulley, the movable jaw moves up and down through the eccentric wheel, when the movable jaw rises, the toggle plate approaches the fixed jaw plate, and at the same time the material is crushed or split to achieve the purpose of crushing; when the movable jaw goes down, the angle between the toggle plate and the movable jaw becomes smaller, and the movable jaw leaves the fixed jaw under the action of the tie rod and spring. In the mean time, the crushed material has been discharged from the lower opening. With the continuous rotation of the motor, the jaws do periodic motion to crush and discharge materials to achieve mass production. The jaw crusher has the characteristics of large crushing ratio, uniform product size, simple structure, reliable operation, simple and convenient maintenance, and economical operating costs.

Why SMAT jaw crusher so popular?
- The internal structure of the equipment is precise and the craftsmanship is sophisticated. All parts are made of materials with wear resistance and strong compression resistance, which enhances the compression resistance and wear resistance of the parts. For example, the movable jaw is made of high-quality manganese steel, and the eccentric shaft is processed with forging billets, which improves the wear resistance and working reliability of the jaw crusher parts.
- The jaw crusher has a deep crushing cavity and no dead zone, which improves the feeding capacity and output, and is not prone to material blocking. The crushing ratio is large, the product particle size is uniform, the output is high, and the energy consumption is low.
The jaw crusher is equipped with a wedge block discharge port adjustment device, which is simpler, safer and faster to adjust the discharge port. The centralized lubrication system is adopted, the lubrication for each parts is simple and fast, and the daily maintenance is convenient.
- Using finite element analysis technology, the crusher has high strength, and is equipped with eccentric shaft bearings that are more durable than other crushers, and the bearing capacity and sealing effect of the bearing are improved.
Q:How we do Jaw Crusher Maintenance?
Maintenance is very necessary for jaw crushers. In order to ensure the normal operation of the jaw crusher, in addition to correct operation, planned maintenance must be carried out, including daily maintenance inspections, minor repairs, medium repairs and major repairs.
- After the equipment is running normally, the feeding can be started.
- The material to be crushed should be evenly fed into the crushing cavity, and side feeding should be avoided to prevent uneven load or unilateral sudden increase.
- Under normal circumstances, the temperature rise of the bearing should not exceed 350 C, and the high temperature should not exceed 700C, otherwise it should be stopped immediately, and the cause should be identified and eliminated.
- Before stopping, the feeding work should be stopped first, and the motor can be turned off after the crushed materials in the crushing chamber are completely discharged.
- During crushing, if the machine stops due to the material blocking in the crushing cavity, the motor should be turned off immediately, and the material must be eliminated before starting again.
