Jaw crusher though is an old crushing equipment, but because of its simple structure, reliable, easy to manufacture, easy maintenance, etc., still in metallurgy, mining, building materials, chemical industry and railways sectors widely available. In the mine, which is mostly used for hard or medium hard ore crushing and broken. Jaw crusher with hydraulic safety device, namely reliable and secure, and easy troubleshooting. Large and medium-sized crushers are generally used cast babbitt bearings, it can withstand greater impact loads, and more wear-resistant. Small jaw crusher multi-bearing, its high transmission efficiency and easy maintenance.
Jaw crusher work priciple: motor drive belt and pulley, through the eccentric shaft to move the jaw up and down movement, when the movable jaw rises between toggle plate and moving jaw angle becomes larger, thus promoting the moving jaw plate close to the fixed jaw plate, and at the same time the material is crushed or split pieces to achieve the purpose of crushing; when the movable jaw down, between toggle plate and moving jaw angle smaller, movable jaw plate under the action of the rod, spring, leaving the fixed jaw plate, this time crushed material discharged from the crushing chamber mouth. With the motor continuously rotating and mobile jaw crusher for crushing and waste material periodically, to achieve mass production. Procedure 1. crusher must start under load. 2. Before the start, carefully check the tightness of the components of the crusher, spring elastic case, the tightness of the belt. 3. When you start, you want to carefully check the crusher tooth plate is loose every time, and according to the material sample size, adjusted for Hubei mouth; unusual circumstances such as when to stop working, thorough treatment and troubleshooting. 4. After the crusher starts operating speed up to speed before feeding; strictly prevent steel, ultra-hardness of objects into the machine, so as not to damage the parts. 5....
