PE-400x250

The small jaw crusher is most suitable for crushing various soft and hard ores with a compressive strength not higher than M (MPa). The maximum size of the crushed materials must not be greater than that specified in the technical parameter table. Small jaw crushers are widely used in industrial sectors such as mining, metallurgy, cement, chemicals, construction, refractory materials and ceramics for medium and fine crushing of various medium-hard ores and rocks. The working mode of small jaw crusher is curved extrusion type. As the motor continuously rotates, the movable jaw of the crusher makes periodic motion to crush and discharge materials, realizing mass production. Its motor drives the belt and pulley, and the movable jaw moves through the eccentric shaft. It moves up and down. When the movable jaw rises, the angle between the toggle plate and the movable jaw becomes larger, thus pushing the movable jaw plate closer to the fixed jaw plate. At the same time, the material is crushed or chopped to achieve the purpose of crushing. When the movable jaw moves downward, The angle between the toggle plate and the movable jaw becomes smaller, and the movable jaw plate leaves the fixed jaw plate under the action of the pull rod and spring. At this time, the crushed material is discharged from the lower opening of the crushing chamber.
