As one of the important equipment in the mining market, the jaw crusher has a huge market foundation. When building a crushing production line, most investors will consider installing a jaw crusher as a primary crushing device in the primary crushing position. With the development of mineral resources and beneficiation industry, the jaw crusher is widely used in various fields and can be said to be one of the most common crushing equipment.
1. How to choose the casting material of the jaw crusher?
- High manganese steel jaws
High manganese steel jaws are the best choice for large jaw crushers. When the material is big and heavy, it will strongly affect the wear of jaw crusher equipment. Because they have to handle larger chunks, these are easier to get into the machine than lighter chunks without sacrificing any efficiency or jaw crusher performance within their capabilities. High manganese steel is the traditional material of jaw crusher jaw plate, which has good impact load resistance. However, due to the structure of the crusher, the opening angle between the movable and fixed jaws is too large, which is easy to cause the abrasive to slide.
- Medium manganese steel jaws
When dealing with materials such as granite, concrete or quartz, medium manganese steel jaws will be your best choice. With its strong hardening ability and self-protection mechanism, crushing high-hardness objects under these conditions can significantly reduce the wear rate of crusher components.
- Carbon low alloy cast steel jaws
In the small and medium-sized jaw crusher equipment, the jaw plate made of medium carbon-low alloy steel is more suitable for small and low impact conditions. They avoid the disadvantages of high manganese steels, such as difficulty in achieving application hardness or economic benefits in terms of manufacturing costs and long-term durability. Especially if you take into account the wear and tear from heavy crushing, how expensive replacement parts can get!
2. Factors to consider when choosing the right jaw crusher
The jaw plate is the part of the jaw crusher that is in contact with the material to be crushed. When crushed, this area is mechanically stressed and must therefore be made of a hard material to resist wear. The jaws are not in direct contact with any moving parts inside the machine, so its material is usually less expensive than other parts.
- Material hardness: Harder materials will require less frequent replacement and extend the overall life of the jaw crusher.
- Impact Resistance: Impact value is the ability of a material to absorb kinetic energy during an impact event while still retaining its shape without any deformation. Materials with low impact values generally perform less well in applications because they are more prone to fracture or cracks under pressure. Higher impact values generally indicate greater toughness and stiffness of the material used.
- Fracture Toughness: Fracture toughness is the ability to withstand any crack growth and remain intact when subjected to an applied load. Fracture toughness is one of the most critical properties of a jaw material because it provides resistance to crack propagation under repetitive stress conditions.
Corrosion Resistance: The ability to resist rust or other forms of corrosion can significantly affect the life and performance of the jaws.
3. How to choose jaw crusher manufacturers
- Quality of crushing equipment: Quality is the soul of crusher manufacturing enterprises and the internal driving force for the development of crusher manufacturing enterprises. Only by strictly controlling the quality, can high-quality equipment be produced, the service life of the equipment will be longer, the performance of the equipment will be better, and the quality will be better. Jaw crusher equipment can create more economic benefits for users and is well received by users.
- The crusher manufacturer should be formal: when users buy crusher equipment, they should choose a regular manufacturer, so that the manufacturer has a high reputation, the crusher equipment produced has excellent performance, stable operation, low failure rate in the production process, and It can save the maintenance cost for the user, thereby improving the economic benefit of the user and saving the cost.
- The manufacturing process mainly refers to the structure and shape of the equipment itself, as well as some details such as whether the steel plate welding is flat, clean and seamless. As we all know, generally high-quality equipment is finely crafted, and every detail is well handled. The entire welding area is flat and clean, and there is no gap in each welding area. The equipment has long service life, good quality and high production efficiency.
- After-sales service of crusher manufacturers: perfect after-sales service is also a point that users need to pay special attention to when purchasing. Good after-sales service can escort the user’s follow-up production. Only powerful crusher manufacturers have independent service departments, and after-sales service can better reflect the strength of the manufacturers. It can independently develop and manufacture jaw crusher equipment, make its own brand, and the equipment is more suitable for the needs of the crushing wind direction.
4. JXSC Jaw Crusher
It is used in mining, smelting, building materials, highways, railways, water conservancy and chemical industries, it can process and crush quartz stone, bluestone, river pebbles, pebbles, limestone, iron ore and other stones.
(1) A systematic and comprehensive optimization design is adopted, and the body adopts an integral cast steel structure with high strength and good stability.
(2) The jaw crusher is widely used and can be used to crush various materials with a compressive strength not exceeding 320MPa, especially for the crushing of large hard materials, such as granite, basalt, shale, iron ore and other stone materials.
(3) There are many models of jaw crushers, including large jaw crushers and small jaw crushers. The hydraulic discharge opening adjustment device and the screw type discharge opening adjustment device can be selected by customers. The adjustment range of the discharge opening is large and flexible. Good, save time and effort, and can meet the different needs of customers.
(4) Jaw crusher The eccentric shaft of the jaw crusher has a high rotational speed, so that the crushing force is large and the output is high. The structure is simple, the work is reliable, the maintenance cost is low, and the fixed and mobile types can be customized without delaying the normal work progress of customers.
(5) With the large-scale, green and environmental-friendly imitation of mine crushing equipment, jaw crushers have also improved the level of technical research and development. It effectively solves the problems of dust pollution and noise pollution in the production process, reduces the pollution to the environment, greatly improves the production efficiency, and adapts to the development of society.
Choosing a suitable manufacturer is actually the same as choosing a reliable partner. The most important point in finding a partner is win-win cooperation. Customers trust jaw crusher manufacturers to purchase jaw crusher equipment, and manufacturers provide customers with equipment that meets the quality standards and supports after-sales service. Then the choice should take the after-sales service into consideration, and choose a jaw crusher manufacturer with strength and good after-sales service.
