Jaw Crusher, Stone Crusher, Mining Crusher manufacturer / supplier in China, offering Economical Sandstone Fine Crush Small Stone Jaw Crusher Lime Primary Jaw Crusher, Mining Equipment Hydraulic Jaw Crusher for Gold Mining, Hard Stone Jaw Crusher Mobile Stone Crusher Line for Sale and so on.
The jaw crusher is used in the first process of crushing various minerals and rocks. It can process various ores with a compressive strength not higher than 320MPa to a medium particle size at one time. It is often used to form a complete set of sand and gravel production lines with cone crushers, impact crushers, and sand making machines and so on, which are widely used in mining, metallurgy, chemical, building materials, power, water conservancy, transportation and other fields.
The jaw crusher is mainly composed of a frame, an eccentric shaft, a large belt pulley, a flywheel, a side guard, a toggle, a toggle back seat, a clearance screw, a return spring, a fixed jaw and a movable jaw. The crushing method of jaw crusher is curved extrusion type. When working, the motor drives the belt and pulley to move 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, thereby pushing the movable jaw plate closer to the fixed jaw plate, and the material passes through the two jaws. The squeezing, rubbing, and grinding between the plates realize multiple crushing; when the movable jaw moves down, the angle between the toggle plate and the movable jaw becomes smaller, and the movable jaw leaves the fixed jaw under the action of the pull rod and spring, and the material has been crushed under the action of gravity, it can be discharged freely through the discharge port at the lower part of the jaw cavity. With the continuous rotation of the motor, the movable jaw is periodically crushed and discharged to realize mass production
* Can withstand strong impact Split welded cast steel frame with simple structure and strong impact resistance; heavy eccentric shaft and bearing ensure the impact resistance of the movable jaw assembly; a heavy guard plate is installed above the movable jaw to withstand the strong impact of materials.* High-quality material finishing The jaw plate and side guard plate are made of high manganese steel, the bracket plate is made of gray cast iron, and the eccentric shaft is made of high-strength forged steel. They are made through multiple precision machining, heat treatment and flaw detection, and have sufficient rigidity and strength.* Overload protection mechanism When the equipment is working, materials exceeding its crushing capacity may enter. These materials will adversely affect 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.* Easy to operate and maintain Gasket type discharge adjustment device, centralized lubrication system, easy to operate and easy to maintain; the jaw plate is a symmetrical structure, which can be used up and down after being worn, which increases the life cycle and saves replacement costs.* Energy saving and environmental protection The use of deep cavity crushing, no dead zone, greatly improves the feeding and crushing efficiency, and the single machine saves 15%-30%, and the system saves more than twice the energy.
