Jaw crusher is mainly applied in crushing multiple ores and large block materials into medium granularity, the materials’ compression strength not more than 320Mpa. Jaw crushers can be classified two kinds: PE series coarse jaw crusher and PEX fine jaw crusher. PE and PEX series jaw crushers have the complete specifications, and the feeding granularity of jaw crushers is 125mm-1020mm. They are the best choice for the primary crushing. Jaw crusher is also used in mine, metallurgy, building materials, road building, rail building, water conservancy, chemical industry and other industries.
Our company has the proficient craftsmanship of manufacturing jaw crusher, and we reformed the techniques audaciously, then produced the jaw crusher of more superior, better quality, better satisfying the customers. Especially, the design and production, by we absorbing the domestic and international advanced technology, one-up other manufacturers. The large jaw crusher is one of our competitive product for customers, it is especially suited for the primaty crushing of limestone, shale, basalt, cobble, bluestone, multiple ores, etc.
Performace Characteristic
(1) deep crushing cavity, no blind area, feeding more fluently and higher production capcity.
(2) larger broken ratio and the end products are epigranular.
(3) the adjusting device of discharge hole is spacer model with the reliable performance, convenient use, and large adjustable range. The design make the machine flexible.
(4) lubricating system with safe performance, replacing the parts conveniently, and little workload of maintaining.
(5) simple structure, reliable performance, low operating charges.
(6) Energy-saving: the stand-alone can reduce the energy consumption by 15-30% while the whole system can save energy by double.
(7) Large discharge open range, which can meet different customers' requirements.
(8) Low noise and dust pollution.
Working Principle
PE/PEX series jaw crushers adopt survilinear motion extruding. The motor drives the belt and pulley, then the eccentric shaft make the swing jaw plate up-and-down move. When the swing jaw plate raises, the included angle between elbow board and swing jaw plate should get larger, accordingly swing jaw plate is getting near to the fixed jaw plate. At the same time, the materials are extruded, twisted, and grinded. When the swing jaw plate gets down, the included angle between the elbow board and swing jaw plate should get smaller, accordingly the swing jaw plate leave the fixed jaw plate by the effect of draw bar and spring. At the same time, the crushed materials are discharged. With the continuous run of the moter, the jaw crusher operates and discharges peridically, thus realizing the batch production.
