Introduction of jaw crusher:
Jaw Crusher, including coarse crusher and fine crusher, is featured by large ratio of reduction, uniform size, simple structure, reliable working, easy maintenance, and low operating cost. Its compression strength isless than 320Mpaand the feeding size ranges from 125mm to 1020mm.As the preferred equipment for primary and secondary crushing, jaw crusher absorbs the advantages of similar productsin domesticand abroad in terms of design, production and after-sales service.It is widely applied in the mines, smelting, building materials, highway, railway, water conservancy and chemicals etc.
Why choose us?
Our PE Jaw crusher has:1.Large capacity: deep crushing cavity canincrease the feeding capacity and output, itimproves working efficiency to a great extent.2. High ratio of reduction: high ratio of reduction can greatly decrease the power consumption and wear loss.
3. Large adjustable range: adjustable gasket device canincrease the flexibility of the equipment which can meet dfferent demands.
4. Easy maintenance: safe and reliable lubricating system make customer easy to change the parts, which greatly decrease maintenance workload.
5. Low operating cost: Simple structure and reliable operation will guarantee your low operating cost.
6.Energy saving: singlemachine can save energy by 15%-30%, which system can save more than double.7.Wide range of choices: we provide different dimensions of product which can meet various needs.
Working principle of jaw crusher:
♦ Under the power ofmotor,eccentric shaft is driven by the belt and belt wheel to make the movable jaw move up and down.
♦ When the movable jaw ascends, the angle between toggle plate and it will become larger. Then the movable jaw plateis pushed toward thefixed jaw plate. When the pressure rises beyondwhat the materials can bear, the crushing happens.
♦ Otherwise, when the movable jaw descends, the angle will become smaller. With the movable jawswinging to the opposite direction and awayfrom the fixed jaw plate, the crushed material willfall downdue to gravity.
♦ Every periodical movement of the movable jaw willput the crushing effect on the materials. The crushed materials will be discharged through the discharge opening after several periods.
Operating cycle of jaw crusher:In the process of large stones crushed into small ones, the first-step crusher is called primary crusher. The jaw crusher is of the most common use and hardest one. The materials are fed into crushing cavity from the top, and thenforced to the cavity wall by the jaw tooth which is driven by the eccentric shaft throughout the frame, and crushed into smaller stones. The eccentric movement is normally made by the fly wheels fixed on both ends of the shaft. The roller bearings in support of the flywheels and eccentricity must bear the large impact load, abrasive sewage, and high temperature. In spite of that, the jaw crusher can work reliably, which is the key link for guaranteeing the production efficiency.
