Crusher is an indispensable equipment in the process of crushing ore, among which jaw crusher is particularly important. The crusher can crush more than 200 kinds of soft and hard stones below 1200mm, and is widely used in large-diameter stone processing and large-scale stone factories.
1. Working principle of jaw crusher
The jaw crusher drives the belt and pulley through the motor, and the eccentric shaft makes the movable jaw move up and down. When the movable jaw rises, the angle between the toggle plate and the movable jaw becomes larger, thereby pushing the movable jaw plate and the fixed jaw plate to approach. It is crushed or split 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 leaves the fixed jaw plate under the action of the pull rod and spring. The lower opening of the cavity is discharged. With the continuous rotation of the motor, the crusher jaws periodically crush and discharge materials to achieve batch production.

2. Performance advantages of jaw crusher
1. The unique deep V cavity design, combined with the large stroke, suitable rotational speed and flywheel inertia formed by the large inclination bracket, ensures efficient kinematic performance and higher crushing ratio, and the processing capacity is higher than that of the traditional jaw type. Crusher increased by more than 50%.
2. The frame with modular, non-welded structure avoids the problem of welding stress concentration, improves the ability of the equipment to withstand impact loads, and enhances the durability and stability of the machine.
3. The integrated motor base reduces the installation space of the crusher and saves the installation time. It is more convenient and quick to adjust the screw to adjust the tension of the V-belt; the appearance of the whole machine is more compact and beautiful.
4. The overall bearing box structure is adopted to ensure complete coordination with the frame, avoiding additional load on the bearing box, and the bearing life is longer and more reliable.
5. The hydraulic wedge-type discharge port adjustment mechanism is adopted to adjust the size of the discharge port steplessly, which makes the adjustment of the discharge port simple, safe and fast, saving labor.
6. When the equipment is working, materials that exceed its crushing capacity may enter. These materials will have adverse effects on the operation of the equipment, and even damage the equipment. At this time, the bracket will break by itself to protect the equipment from damage.
