Jaw crusher is an early type of crushing equipment, which is widely used in metallurgy, chemical industry, building materials, power, transportation and other industrial sectors due to its simple structure, sturdy, reliable operation, easy maintenance and repair, and relatively low production and construction costs. It is used for crushing various ores and rocks with compressive strength ranging from 147 to 245 MPa, including coarse, medium and fine crushing. In recent years, our factory has specially developed a powerful jaw crusher to meet the needs of crushing high-strength and high hardness micro carbon ferrochrome in industrial sectors such as metallurgy, mining, and construction. Jaw crushers are generally divided into two types: compound swing jaw crushers and simple swing jaw crushers, mainly used for coarse and medium crushing. In recent years, compound pendulum jaw crushers and high-strength, high hardness micro carbon ferrochrome crushers have emerged for fine crushing. As is well known, the main problem with jaw crushers is the low lifespan of the jaw plates. To this end, the company has developed specialized materials and adopted hydraulic couplings on large machines to improve the starting process and avoid overload damage, thereby enhancing equipment performance.

Scope of use of jaw crusher: Jaw crusher is mainly used for medium particle size crushing of various ores and large materials, and is widely used in industries such as mining, smelting, building materials, highways, railways, water conservancy, and chemical industry. The maximum compressive strength of the crushed material is 320MPa Performance characteristics of jaw crusher: large crushing ratio, uniform product particle size, simple structure, reliable operation, easy maintenance, and low operating costs.

Working principle of jaw crusher: During operation, the electric motor drives the eccentric shaft to rotate through the pulley, causing the moving jaw to periodically approach and leave the fixed jaw, thereby causing multiple crushing of the material such as squeezing, rubbing, and rolling, gradually reducing the material from large to small and falling until it is discharged from the discharge port.

Specification and Performance Parameters Table of Jaw Crusher

The jaw crusher is a widely used crushing equipment, which can be divided into compound swing jaw crusher (i.e. single elbow jaw crusher) and simple swing jaw crusher (i.e. double elbow jaw crusher) according to its structural characteristics. Generally speaking, the compound pendulum jaw crusher is suitable for crushing various ores and rocks with a compressive strength of 250MPa or less for coarse and medium crushing. Among them, crushers with three specifications above PEF 0609 can also crush various hard ores and rocks; The PEF-X fine crushing compound swing jaw crusher is generally only suitable for finely crushing ores and rocks with medium to low hardness. The PEJ simple swing jaw crusher can crush ores and rocks of various hardness, especially for crushing hard and abrasive stone materials.

Our company produces two series of various specifications of E-type crushers, which are widely used in crushing operations in metallurgy, mining, building materials, chemical, cement and other enterprises due to their simple structure, reliable performance, easy operation, convenient maintenance, and safe use Our company has improved the design of all E-type crusher series according to international advanced standards and added new specifications that are suitable for the market to meet the growing needs of domestic and international markets.
