Product description
Jaw crusher is commonly known as jaw crusher, also known as tiger's mouth. The crushing cavity is composed of two jaw plates, the movable jaw and the static jaw, which simulate the movement of the two jaws of animals to complete the material crushing operation. It is widely used in the crushing of various ores and bulk materials in mining and smelting, building materials, highways, railways, water conservancy and chemical industries.
Working principle
Jaw crusher is mainly composed of frame, eccentric shaft, large pulley, flywheel, side guard plate, toggle plate, toggle plate rear seat, gap adjustment screw, return spring, fixed jaw plate and movable jaw plate.
The crushing method of jaw crusher is curved extrusion type. When working, the motor drives the belt and pulley, and moves the movable jaw up and down through the eccentric shaft. 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, and the material passes through the two jaws. Multiple crushing is achieved by squeezing, rubbing, grinding, etc. between the plates; 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, and the crushed materials Under the action of gravity, it is discharged freely through the discharge port at the lower part of the jaw cavity. With the continuous rotation of the motor, the movable jaw performs periodic crushing and discharge to achieve mass production.
Feature
1: It can withstand strong impact; the split welded cast steel frame has a simple structure and strong impact resistance; the heavy-duty eccentric shaft and bearings ensure the impact resistance of the movable jaw assembly; a heavy-duty guard plate is installed above the movable jaw to ensure Withstand the strong impact of materials.
2: High-quality material finishing; the jaw plate and side guard plate are made of high manganese steel, the toggle plate is made of gray cast iron, and the eccentric shaft is made of high-strength forged steel. They are made after multiple precision machining, heat treatments and flaw detection inspections. , with sufficient stiffness and strength.
3: Overload protection mechanism; 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 may even damage the equipment. At this time, the toggle plate will break on its own to protect the equipment from damage. .
4: Easy to operate and maintain; the gasket-type discharge adjustment device and centralized lubrication system are easy to operate and maintain; the jaw plate has a symmetrical structure and can be swapped up and down after wear, extending the service life and saving replacement costs.
