Jaw crusher is crushing equipment appeared earlier, its structure is simple, rugged, reliable, easy maintenance and repair as well as production and construction costs relatively low, so now is still widely used in metallurgical, chemical, building materials, electricity , transportation and other industrial sectors, for compressive strength 147-245MPa of ores and rocks of coarse, medium, fine.
In recent years, SBE machine in order to meet the metallurgical, mining, construction and other industrial sectors broken high strength, high hardness of low carbon ferrochrome needs, specifically developed a new type jaw crusher.
The jaw crusher is mainly used for a variety of ores and bulk materials of medium-grained crushing, widely used in mining, smelting, building material, highway, railway, water conservancy and chemical industries. Maximum compressive strength of the material to be broken 3
Jaw Crusher Features
1, using the world-class manufacturing processes, selection of the most high-end production of materials.
2. More advanced movable jaw assembly to make it more durable, movable jaw assembly adopts high-quality cast steel structure, and through two large cast steel flywheel drive, in addition to heavy eccentric shaft has also adopted forging billet for processing all this makes both jaw crusher with exceptional reliability.
3, using integrated steel bearing structure, to ensure that exactly match the broken frame, but also greatly enhance the radial strength of the bearing seat, and split bearing not have this advantage.
4, the use of finite element analysis technology, the crusher has a higher strength.
5, the crushing cavity symmetrical "V" shaped configuration so that the actual width of the nominal inlet width of the inlet consistent.
6, the discharge opening to adjust more quickly and conveniently. Jaw crusher discharge port is equipped with wedge adjustment device which is simpler than shimming, safer and faster.
7, selection of bearing size larger, higher carrying capacity. SBE jaw crusher are equipped with the same specifications than other crushers greater and more durable eccentric shaft bearings, the higher carrying capacity and effective labyrinth seal greatly extend the service life of the bearing.
8, the use of tooth shield, increasing the effective length of the jaw, higher yields.
working principle
Jaw crusher song moving extrusion type, working principle is: motor-driven belt and pulley, through the eccentric shaft to move the jaw up and down movement when moving jaw rises between toggle plate and moving jaw angle between large, thus promoting movable jaw plate close to the fixed jaw plate, simultaneously with the material being crushed or split pieces to achieve the purpose of crushing; when moving jaw down, the angle between toggle plate and moving jaw smaller, movable jaw plate under the lever action, spring , away from the fixed jaw plate, then the crushed material from the crushing chamber discharge port. With the continuous rotation of motor broken motor jaw for periodic motion crushing and waste material, to achieve mass production.
