Ensure that the material entering the jaw crusher meets the specified particle size range to avoid excessive wear of the tooth plate by materials that are too large or too small. At the same time, prevent iron blocks or other impurities from entering the machine to avoid serious wear of the tooth plate. 6. Select high wear-resistant materials:
8. Prohibit long-term overload operation of the equipment: Long-term overload operation of the equipment will cause cracks at the root of the tooth plate, resulting in failure of the tooth plate. Therefore, during the operation of the equipment, attention should be paid to the combination of work and rest to avoid long-term overload operation.
However, during daily production process, due to the overload operation of jaw crusher, the hardness of crushed material and the quality of toggle plate is not up to the standard, the eccentric shaft of jaw crusher is easy to be broken. The main part of jaw crusher tilts during lifting process, the eccentric shaft is bent unilaterally.

Reason: The main reason for the damage of the adjusting screw is the over-adjustment of the screw, and the crusher realizes the mutual locking of the stepless adjustment mode by adjusting the two screws on both sides at the same time.
What are the reasons for cone crusher jamming? ... Mobile Jaw Crusher Plant; SPECIAL TOPIC. ... When the cone crusher is in a state of overload operation for a long time, although there is an overload protection device, it cannot completely avoid damage to the equipment. The spindle is prone to breakage and the equipment is jammed.
The main reason is that the structural design of the main shaft is unreasonable, and it is easy to generate stress concentration, which is manifested in the large interference of the mating surface of the main shaft and the movable jaw, the filter fillet is too small and there is no unloading groove, which is easy to cause long-term overload of ...

that the jaw crusher can be converted to suit different applications. The BB 51 is driven by a powerful single-phase AC motor with 1100 W. A disc spring package and thermal overload protection device protect the jaw crusher against overloading. Due to permanently lubricated bear-ings and its solid design, the BB 51 is virtually maintenance-free.
Common Crusher Problems and Causes. Even though crushers are built to withstand heavy-duty work, several issues can arise: Overloading Overloading the machine can damage core components like jaws or hammers.
The service life of the jaw crusher is directly related to its frequency of use. If the crushing operation is carried out frequently, the equipment parts are easily worn, which naturally shortens the service life. 5. Overload and incorrect operation: The equipment must avoid overload operation during use.
A jaw crusher ( 10 ) includes a fixed jaw ( 16 ) and a swing jaw ( 18 ), which define a crushing chamber ( 26 ). The swing jaw ( 18 ) is mounted for cyclic movement in the direction of the fixed jaw ( 16 ), for crushing material between the two jaws. A cross beam ( 42 ) is adjustably received in apertures ( 40 ) provided in the walls ( 12, 14 ) of the frame ( 11 ).
Accidents around the use of a jaw crusher can be as simple as a sprained ankle or as monumental as a life-threatening incident. Here are a few common causes of injuries: Slips, Trips, and Falls
Therefore, New High-end Heavy Industry will analyze the reasons for the overload of the main machine of the multi-cylinder cone crusher and provide corresponding solutions. 1. Causes of spring cone overload (1. Bad working environment: The working environment temperature of the spring cone is too high or too low, and the air contains a lot of ...
What Cause Jaw Crusher Toggle Plate To Broken. What Cause Jaw Crusher Toggle Plate To Broken. Successful jaw crusher maintenance requires the right resources, the right tools and the right approach, says bill macini, a service technician.Certainly when an operation is down, whether for preventive maintenance or component failure, there is always the pressure to get …
Jaw crusher. 1. Structural problems of jaw crusher. The structure of the jaw crusher is complex. If the design is unreasonable or the parts are worn due to long use time, it will affect its feeding speed. For example, serious wear of key parts such as jaw plate and swing plate will increase the resistance of the crusher and slow down the ...
It means likewise that double capacity is obtainable for products which might ordinarily be reduced by a single jaw crusher. The reason for this increased capacity is due to the fact that the Bakstad has twice the area of outlet found in ordinary jaw crushers. Jaw crusher maintenance : …
Generally, inexperienced operators will further increase the clamping force, resulting in overload breakage of jaw crusher pull rod and overload deformation of the mold. Reasons: 1) The main engine of the jaw crusher turned over during the hoisting process, causing the eccentric shaft to bend under the force on one side; 2) The hardness of the ...
Controls: When overload occurs the feeder will stop but the crusher and product conveyor will continue to operate until re-set. JAW CRUSHER Hopper type: Boltless hydraulic folding feed hopper with over centre struts and wedgelok system. Hopper length: 4915mm. Hopper width: 2413mm. Hopper capacity: Up to 10m3 gross. Hopper body: 15mm thick ...
1. In order to achieve a higher output, the user increases feeding capacity, which results in jaw crusher blockage. 2. Too much material in the lower chamber of the jaw crusher can't be discharged, so it resisters the moving plate and causes the motor to overload and stop. 3. The downstream equipment stops and the jaw crusher continues to break. 4.
In particular, very hard rock tends to slip upward rather than break. Choke feeding this kind of material can overload the motor, leaving no option but to regulate the feed. Smaller particles, which weigh less, and harder particles, …
