Jaw crusher is an early type of crushing equipment. Due to its simple structure, sturdiness, reliable operation, easy maintenance and repair, and relatively low production and construction costs, it is still widely used in various industrial sectors such as roads and bridges, metallurgy, chemical industry, building materials, power, transportation, etc., for crushing various ores and rocks with compressive strength between 147-245MPa in coarse, medium, and fine crushing.
Generally speaking, the compound pendulum jaw crusher is suitable for various ores and rocks with a compressive strength of less than 250Mpa in coarse and medium crushing. Among them, crushers with PEF0609 and above specifications 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 simple pendulum jaw crusher can crush ores and rocks of various hardness, and is particularly suitable for crushing hard and highly abrasive stones.
Jaw crusher PE250 × 1000 product features
The jaw crusher is widely used in construction materials and mines, mainly due to its complete range of models, stable performance, and large production capacity. Jaw crushers are mainly used as coarse crushers and intermediate crushers in the mining, building materials, and infrastructure sectors. According to the width of the feeding port, there are three types: large, medium, and small. Large machines have a feeding port width greater than 600mm, medium machines have a feeding port width between 300-600mm, and small machines have a feeding port width less than 300mm. The working part of a jaw crusher consists of two jaw plates. One is a fixed jaw plate (fixed jaw), which is vertically (or slightly outward inclined at the upper end) fixed on the front wall of the machine body, and the other is a movable jaw plate (moving jaw), which is inclined in position and forms a crushing chamber (working chamber) with a fixed jaw plate that is larger in the upper part and smaller in the lower part. The movable jaw plate performs periodic reciprocating motion against the fixed jaw plate, sometimes separating and sometimes approaching. When separated, the material enters the crushing chamber and the finished product is discharged from the bottom; When approaching, the material placed between the two jaw plates is crushed by compression, bending, and splitting.
Jaw crusher PE250 × 1000 Performance Characteristics and Scope of Application
Jaw crushers are mainly used for medium particle size crushing of various ores and bulk materials, and are widely used in industries such as mining, smelting, building materials, highways, railways, water conservancy, and chemical engineering. The maximum compressive strength of the crushed material is 320MPa.
Performance characteristics: high crushing ratio, uniform product particle size, simple structure, reliable operation, easy maintenance, and low operating costs.
Working principle: During operation, the electric motor drives the eccentric shaft to rotate through the belt pulley, causing the moving jaw to periodically approach and leave the fixed jaw, thereby squeezing, rubbing, and crushing the material multiple times, causing the material to gradually fall from large to small, until it is discharged from the discharge port.
