European jaw crusher

   We are the world's leading manufacturer of rock and mineral processing equipment. Since the end of the twentieth Century, we have installed tens of thousands (sets) of crushing equipment all over the world. Today, our research and development of the European version of jaw crusher has indisputably become the world's most popular jaw crusher. When considering the efficient crushing of hard and heavy abrasive materials, we should first choose the most advanced crushing technology and the European version of the jaw crusher.

Structure composition

  The European version jaw crusher mainly has the frame part, the eccentric shaft rotation part, the crushing chamber work part, the insurance device, the material discharge mouth, the adjustment device and so on.

1 . frame parts: the side plate, front box assembly, back box weldment and so on.

2. eccentric shaft rotation part: mainly by moving jaw, eccentric shaft, bearing, bearing seat, pulley and so on. Is a major part of the transmission of power.

3. crushing chamber work part: mainly by the jaw plate, moving jaw plate, side lining board, guard board and so on, is the broken material work parts.

4. Safety device: it consists of elbow plate, elbow plate seat, spring, spring pull rod and so on. It is the part of the crusher that can protect the material under abnormal conditions.

5. outlet adjustment device: the device is used to adjust the size of the discharge port, and control the particle size. The utility model is mainly composed of an adjusting fixed block, an adjusting sliding block, a top screw bolt, a slide block, a locking pull rod, etc.

Application range

1, the series jaw crusher mainly used in metallurgy, mining, chemical, cement, construction, refractory materials and ceramics and other industrial sectors, crushing and crushing of various medium and hard ore and rock.

2, the series crusher is most suitable for crushing the compressive strength of not more than 280Mpa of ore, rock, slag, etc., the maximum fragmentation of broken material shall not be greater than the technical parameter table.

Working principle

   The motor drives the belt and the pulley, and the movable jaw swings up and down by the eccentric shaft. When the movable jaw drives the movable jaw plate to move toward the jaw plate, the material is crushed or broken. When the movable jaw and the movable jaw fall back under the action of the eccentric shaft and spring, the material previously crushed or broken is discharged from the lower discharge opening of the jaw plate. With the continuous rotation of the motor, the motor jaw is periodically crushed and excreted to achieve mass production.

Technological advantage

1.the use of world-class manufacturing processes, choose the most high-end production materials.
2.more advanced movable jaw assembly to make it more durable. The movable jaw assembly is made of high quality cast steel and is driven by two large cast steel flywheels. In addition, the heavy eccentric shafts are machined with forged billets, all of which make the jaw crusher exceptional reliability.
3.The bearing housing adopts the integral cast steel structure. The whole cast steel bearing block can ensure the complete cooperation with the crushing frame, and greatly increase the radial strength of the bearing seat, but the split bearing seat does not have the advantage.
4.using finite element analysis technology, crusher has higher strength.
5.The crushing chamber adopts symmetrical V structure, so that the width of the actual feed opening is consistent with the width of the nominal feed opening.
6.the discharge adjustment is faster and more convenient. The European jaw crusher is equipped with a wedge and a material outlet adjusting device, which is simpler, safer and quicker than the old gasket.
7.the selection of bearings larger specifications, higher carrying capacity. All jaw crushers feature larger and more durable eccentric shaft bearings than other crusher of the same size. The higher bearing capacity and the effective labyrinth seal greatly prolong the life of the bearing.
8.the new type of toothed guard plate is adopted to increase the effective length of the jaw plate, and the output is higher.
