Jaw Stock

Use of the product:

The supporting jaw crusher is used to adapt to various scenarios such as mines, construction, water conservancy, roads, etc. It is used for the crushing operation of all kinds of medium and hard materials, providing core power for the crushing process and ensuring the crushing efficiency and operation stability.

Application scenario:

Jaw Stock is one of the core load-bearing and moving components in the jaw crusher. It is mainly used to install the jaw plate and transmit the crushing force, and realise the reciprocating movement through the eccentric shaft drive, so as to complete the extrusion and crushing of the material.

In practical application, Jaw Stock is widely used in mine crushing, sand and stone aggregate production lines and metallurgical building materials industries. It is mainly used to support the moving jaw system and withstand high-strength impact loads. Under coarse crushing conditions, it works in cooperation with jaw plate, elbow plate and other parts, and is a key structural component to realise the crushing of large materials.

In the sand and stone production line, Jaw Stock is the core moving structure of the jaw crusher. It is located in the coarse crushing stage at the front end of the whole machine, which has an important impact on the operation stability of the equipment, crushing efficiency and the life of the whole machine.

In addition, this component is widely used in large-scale mining projects, cement building materials and infrastructure projects. It is especially suitable for high-load and continuous crushing conditions. It is one of the indispensable key structural parts in jaw crushers.

FAQ：

Q：What is Jaw Stock and what role does it play in PE/PEX jaw crusher?

A：Jaw Stock is the main body of the core movement of the jaw crusher, which belongs to the main body of the crank connecting rod mechanism.

1. Support load-bearing: the Jaw Plate is locked and fixed externally by Pressure Block, and the Bushing bushing is assembled internally to undertake the driving force of the eccentric shaft recipropating swing;
2. Power conduction: the upper part is suspended on the eccentric shaft, and the lower part is supported by the Toggle Plate to drive the jaw plate to swing back and forth periodically to complete the ore extrusion and crushing;
3. Protective matrix: Isolate the stone and directly flush the worn spindle structure, withstand the huge impact load of the whole crushing process, and the operation stability of the whole machine depends entirely on the rigid support of the moving jaw body.

Q：Which jaw crusher models are suitable for Jaw Stock?

A：The whole series is suitable for all specifications of PE, PEX, EC and JC jaw crushers, covering deep cavity coarse crushing and standard medium crushing full models, and can be supplied with Jaw Plate, Cheek Plate, Toggle Plate and Bushing sets.

Q：What is the essential difference between Jaw Stock and Jaw Plate?

A：Jaw Stock is a permanent load-bearing main body, without direct material wear, and the overhaul cycle is up to several years; Jaw Plate is an outer high-frequency wear-resistant consumable, which directly squeezes the ore and needs to be replaced regularly. The conical surface of the outer wall of the moving jaw body fits the jaw plate. If the moving jaw body is deformed and strained, it will cause the jaw plate to be quickly grind through on one side and the output particle size will be out of control.

Q：Is there any difference in the use of moving jaw bodies in hard rock mines and small and medium-sized sand and stone factories?

A：The ontological structure of the moveable jaw of the same model is the same, only the maintenance standards are different. The impact load of granite, basalt and other high-hard ore production lines is extremely large, and it is necessary to regularly check whether there are cracks and grooves in the pores and outer wall of the moving jaw; the impact of medium-soft materials such as limestone and construction waste is small, and the maintenance cycle of the moving jaw is longer and the loss is lower.

Q：What faults mean that Jaw Stock needs to be repaired and replaced?

A：1. There are obvious strains and deep grooves on the pore cooperation surface of the moving jaw, and the steel bushing is frequently burned; 2. Visible cracks, depressions and deformations appear in the body and spoke plate of the moving jaw, and the equipment shakes violently and makes abnormal noises when running; 3. The curvature of the outer wall is unevenly worn, the moveable jaw plate is frequently and quickly worn on one side, and the output particle size continues to get out of control; 4. The eccentric assembly gap exceeds the standard, and the standard crushing gap cannot be adjusted, and the whole machine continues to fluctuate.

Q：Does the whole series of jaw-broken Jaw Stock always be in stock to support long-term foreign trade bulk supply?

A：PE/PEX/EC/JC mainstream standard models have sufficient year-round inventory, and have their own complete cast steel production line for sustainable mass production. It can supply the moving jaw body separately, and it can also be packaged and shipped with the jaw plate, edge guard plate and bushing, supporting overseas mines and equipment maintenance factories for long-term fixed-point collection and annual stocking by agents.
