Ore crusher work introduction

Crusher is an indispensable equipment in crushing ore process, among which ore crusher is particularly important. The crusher can crush a variety of soft and hard stones, and is widely used in large-diameter stone processing and large-scale stone factories.

The ore crusher is the first rough crushing process. The drive motor drives the large pulley to rotate, which in turn drives the eccentric shaft to rotate, causing the movable jaw to swing periodically, and the crushing cavity to change periodically to squeeze the materials in the crushing cavity for crushing.

When the movable jaw moves away from the fixed jaw under the action of the mechanical tensioning device, the crushed material is discharged from the lower port, and the large particle material enters the lower end of the crushing cavity. The crushing method is a curved extrusion type, and the crushing principle includes multiple crushing such as extrusion, rubbing, and grinding.

The working principle of ore crusher

The ore 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, so as to push the movable jaw plate and the fixed jaw plate to approach. Crushing or splitting 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, and the crushed material flows from the crushing cavity. The lower outlet is discharged. With the continuous rotation of the motor, the crusher jaws periodically crush and discharge materials to achieve batch production.

Ore crusher performance advantages

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 traditional ore crushing. machine 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 tension of the V-belt by adjusting the screw; 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.
