The crushing method of European type jaw crusher is dynamic squeeze. The working principle is: the electromotor drives the belt and pulley to make the movable jaw move back and forth, up and down through the eccentric shaft. The raw material is squashed or splitt when movable jaw plate moves towards fixed jaw together with movable jaw. When movable jaw and movable jaw plate turn back by eccentric shaft and spring, the raw material, which is squashed or split before discharges from the bottom outlet under jaw plate. The bulk-production comes true while electromotor rotates continuously and the movable jaw crushes and discharges the raw material periodically.


1. World-level manufacturing technology is adopted, and highest-level raw material is used.

2. Central lubricating device are installed on the machine, so the bearing is easy to be lubricated.

3. Adjustment of the discharge part is more convenient. The adjustment methods: gasket adjustment, hydraulic assistant adjustment, wedge block and wedge hydraulic adjustment.

4. More advanced movable jaw assembly lengthens life of crusher. Movable jaw assembly is made from cast piece with high-quality, is driven by two large flying wheels which are made from cast steel. Moreover, heavy eccentric shaft is processed by forged mold. All of these make the JC series jaw crusher extremely reliable.

5. Integral cast steel structure is adopted for bearing seat. Integral cast steel bearing matches well with the crusher frame, at the same time, radial strength of the bearing seat is highly strengthened. However, the separate bearing seat does not have this advantage.

6. Finite element analysis technology is adopted to make the crusher much stronger.
7. Crusher chamber adopts "V" structure which could make actual feed width comply with the nominal one.

8. Bearing with larger model and higher load are used. All jaw crusher is equipped with larger bearing compared with same model of normal jaw crusher. Its higher load capacity and effective oil seal will lengthen the life of bearing.
9. A newly designed tooth-shape side plate, makes the available area of jaw plate longer, and enhances the capacity.

10. Pressing bar and support type are used to fix jaw plate.

11. Heavy type protecting plate is installed for bearing seat, accidental damage of bearing seat is avoided.

12. Supporting bar under jaw plate protects movable jaw and frame from being worn down.


Henan Liming Heavy Industry Science & Technology Co., Ltd. is the leading enterprise of rock & mineral processing equipment in the world. Since the end of the 20th century, we've installed more than 10,000 crushing plant all over the world. Nowadays, European type jaw crusher has already become the most popular equipment in the world without controversy. It is the first choice for hard and strong abrasion material.

Q:What are the advantages and disadvantages of the coarse cone crusher compared with the jaw crusher?
Advantages of cone crusher:1 、 reasonable structure, reliable performance, stable operation, high performance price ratio2, large crushing ratio, high yield, low wear3 、 frame adopts high strength cast steel, finishing process, stronger strength4 、 reliable sealing, effectively prolong the cycle of lubricant replacement and the service life of components5 、 hydraulic cleaning chamber, easy to operate and simple6, the whole machine adjustment is operated by the hydraulic system, faster and more labor-saving7, the use of compound cavity type, cube, high yield8, coarse, medium, fine and broken, complex cavity type, large choice spaceDisadvantages of cone crusher: the price is more expensive
Q:Calculation of static load and dynamic load of crusher and selection of bearing
Static load is the total weight of equipment, the dynamic load coefficient of hammer crusher is generally 3-6, dynamic load is the total weight of equipment X, dynamic load factor,
Q:Service life of crusher hammer
When parking, check the gap between the hammer head and the screen bar, between the screen bar and the screen bar, adjust it when necessary, and change the screen regularly. Because the cost of the hammer head is higher than the screen bar, the new screen can use more than 4 to 5 classes as compared with the old screen.
Q:What crushing machine does asphalt recycling break?
Various types of pavements paved with mineral materials in bituminous materials.
Q:Is the jaw crusher broken? What are the main uses and what stone can be broken?
The jaw crusher produced by Jin Hua Machinery is used for crushing, crushing, compressive strength of 147 ~ 245MPa of various ores and rocks in coarse, medium and fine crushing. The maximum compressive strength of the crushed material is 320Mpa. The characteristics of the crusher are: the crushing ratio of the crusher is large, the product size is uniform, the structure is simple, the work is reliable, the maintenance is simple and the operation cost is low. Hubei broken machine working principle: when the motor through the belt wheel drives the eccentric shaft to rotate, the movable jaw cycle around and left for the jaw, which is extrusion, rubbing, grinding and other multiple crushing of material into small materials, gradually falling, until discharged from.
Q:Installation and clearance adjustment of grate for hammer crusher
The grate bars used in the hammer crusher are all of the same size at the time of installation. They are placed along the groove of the grate bar, and the two grate bars are separated by gaskets to ensure the clearance. Changing the spacer of different thickness can change the clearance between the grate bars.
Q:What is the working principle of a hammer crusher?
The main working parts of hammer crusher are rotors with hammers (also called hammers). The rotor is composed of a spindle, a disk, a pin and a hammer.
Q:What kinds of crushers are there?
gyratory crusherIs the use of cone crusher in the shell cavity in the cycle of movement, squeezing and splitting and bending effects on materials, crushing hardness of ore or rock crushing machinery. With spindle crushing cone at the upper end of the supporting bushing in the beam in the middle of the eccentric hole, the lower end is arranged in the shaft sleeve sleeve rotates, crushing cone winding machine moves the center line of the eccentric motion cycle it is continuous, so the working efficiency is higher than that of jaw crusher. In early 70s, the large crusher per hour can handle 5000 tons of materials, the maximum feed diameter up to 2000 mm.The nesting population adjustment and overload insurance in two ways: one is the gyratory crusher by mechanical means, adjust the upper end of its spindle nut, rotate adjusting nut, cone crusher can decrease or increase the discharge becomes larger or smaller, overload, cut off the pin on the drive pulley in order to achieve insurance; the second is the use of hydraulic hydraulic gyratory crusher, the piston is located in the spindle in the hydraulic cylinder, hydraulic piston change under oil volume cone crusher can change the position, thus changing the size of the discharging port. When overloaded, the spindle downward pressure, forcing the hydraulic oil the plunger into the hydraulic system accumulator, broken cone ensuing decline in the increase of the discharge, discharge into the crushing chamber with non - crushed material material (iron, wood etc.) in order to achieve insurance.
Q:What are the requirements for the installation of jaw crusher?
When installing the motor, besides checking the distance from the main engine, the motor pulley shall also be checked in parallel with the center of the main slot wheel to ensure that all the triangle belts work effectively and uniformly.The discharge opening size should be adjusted according to the size and processing capacity of the required products, in adjusting the discharge should disengage the tension spring, to be adjusted, and then adjust the swelling degree of spring is appropriate, to prevent the elbow in work off board adjustment components.
Q:What's the difference between a jaw crusher and a cone crusher?
Jaw crushers, jaw plates, jaw plates, jaw plates, jaw plates and movable jaw plates are the wear parts of jaw crushers. They are square. The running state in the jaw crusher, jaw attached to a movable jaw plate made of compound pendulum movement, the formation of a stone with a fixed jaw angle extrusion. The jaw plate is, therefore, a relatively easy piece of damage in the jaw crusher.
