Jaw Crusher Introduction

The jaw crusher, commonly known as the jaw breaker, is an early type of crushing equipment. Due to its simple and sturdy structure, reliable operation, ease of maintenance and repair, and relatively low production and construction costs, it is still widely used in various industrial sectors such as metallurgy, chemicals, building materials, electricity, and transportation. It is used for coarse, medium, and fine crushing of various ores and rocks with compressive strengths ranging from 147 to 245 MPa. To meet the needs of the metallurgical, mining, and construction industries for high-strength and high-hardness crushing, significant human, material, and financial resources have been invested in the research and development of new jaw crushers. More new models are continuously introduced. Welcome to keep an eye on our factory for updates.

Jaw crushers are mainly used for medium particle size crushing of various ores and large pieces of material, and are widely used in industries such as mining, smelting, construction materials, highways, railways, water conservancy, and chemical industries. The compressive strength of the crushed material does not exceed 320MPa.

Jaw Crusher Performance Features

1. The jaw crushers are all manufactured using advanced production techniques and are crafted from high-end materials.

2. The鄂式破碎machine features a more durable moving jaw assembly, constructed with high-quality cast steel components. It is powered by two large cast steel flywheels and benefits from a heavy-duty eccentric shaft machined from forgings. All these factors contribute to the jaw crusher's exceptional reliability.

3. The jaw crusher bearing seat is made of a monolithic cast steel structure, ensuring a perfect fit with the crusher frame and significantly enhancing the radial strength of the bearing seat. The split-type bearing seat does not possess this advantage.

4. Utilizing finite element analysis technology, the equipment boasts higher working intensity, contributing to increased production efficiency.

5. The鄂式crusher features a symmetrical "V" shaped crushing chamber, ensuring the actual feed opening width matches the nominal feed opening width.

6. Material discharge adjustment is quicker and more convenient. The jaw crusher is equipped with a wedge-type discharge adjustment device, which is simpler, safer, and faster than the old-style gasket adjustment.

7. Larger bearing specifications and higher load-bearing capacity are chosen.鄂式破碎机 are equipped with larger and more durable eccentric shaft bearings than other similarly sized crushers, which, with their higher load-bearing capacity and effective sealing, significantly extend the service life.

8. The jaw crusher features toothed side plates, which increase the effective length of the jaw plate, resulting in higher production output.

Jaw Crusher Working Principle

The jaw crusher operates through a reciprocating extrusion mechanism. Its working principle is as follows: the motor drives a belt and belt pulley, which, through an eccentric shaft, causes the moving jaw to move up and down. As the moving jaw ascends, the angle between the arm and the moving jaw increases, pushing the jaw plate closer to the fixed jaw plate, thereby crushing or splitting the material to achieve the crushing goal. Simultaneously, the material is crushed or split. When the moving jaw descends, the angle between the arm and the moving jaw decreases, and under the action of the pull rod and spring, the jaw plate moves away from the fixed jaw plate. At this point, the already crushed material is discharged from the lower opening of the crushing chamber. With the continuous rotation of the motor, the moving jaw of the crusher performs periodic motion to crush and expel the material, realizing mass production.

Jaw Crusher Price

When purchasing a jaw crusher, customers not only focus on the performance and quality of the machine itself, but the price is also a significant concern. Especially for jaw crushers, which are produced by many manufacturers, it's crucial to buy with caution, as the cost of a jaw crusher is not inexpensive. The price of a jaw crusher is influenced by various factors, such as the manufacturer, specifications, quality, location, and market demand. Different manufacturers offer varying performance, quality, and prices for their jaw crushers. Therefore, when purchasing a jaw crusher, customers should buy from authorized manufacturers and consult the specific producers for pricing details.
