Stone crusher plant use primary jaw crusher

Product description

The jaw crusher is simple in structure, sturdy, reliable in operation, easy in maintenance and overhaul, and low in production and construction costs. It is widely used in roads and bridges, metallurgy, chemical industry, building materials, electric power, transportation and other industrial sectors. Coarse, medium and fine crushing of various ores and rocks of ~245MPa. In order to meet the needs of metallurgy, mining, construction and other industrial sectors to crush high-strength, high-hardness micro-carbon ferrochromium, our factory has specially developed a powerful jaw crusher.

Performance characteristics

1. Adopt world-class manufacturing technology and select the highest-end production materials.

2. More advanced movable jaw assembly makes it more durable.

3. The bearing seat adopts integral cast steel structure. The integral cast steel bearing seat can ensure complete cooperation with the crushing frame, and also greatly enhance the radial strength of the bearing seat, while the split bearing seat does not have this advantage.

4. Using finite technology, the crusher has higher strength.

5. The crushing cavity adopts a symmetrical "V" shape structure, so that the actual feeding port width is consistent with the nominal feeding port width.

6. The bearing specification is larger and the bearing capacity is higher.

7. The tooth-shaped guard plate is newly adopted, which increases the effective length of the jaw plate and increases the output.

Working principle

The working mode of the jaw crusher is the curved extrusion type. Its working principle is: the motor drives the belt and pulley, and the movable jaw moves up and down through the eccentric shaft. When the movable jaw rises, the angle between the toggle plate and the movable jaw becomes larger, thereby Push the movable jaw plate to approach the fixed jaw plate, and at the same time, the material is crushed or chopped to achieve the purpose of crushing; when the movable jaw goes down, the angle between the toggle plate and the movable jaw becomes smaller, and the movable jaw plate acts on the pull rod and the spring. down and leave the fixed jaw plate, and the crushed materials are discharged from the lower opening of the crushing cavity. With the continuous rotation of the motor, the crushing jaws perform periodic motions to crush and discharge materials to achieve mass production.
