In earlier years, Germany and Former Soviet Union once researched a hydraulic driven jaw crusher. With the increase of production, this jaw crusher can greatly reduce the operating costs. And it is of reliability and flexibility.
The jaw crusher was invented by a American man named E.W. Blake. Since its invention, the structure of the jaw crusher is constantly improved. Since this machine has many advantages such as simple structure, easy manufacturing, reliable working condition and convenient use and repair, it is widely used in metallurgy, mining, building materials and coal and other industries.
In order to perfect the performance of the jaw crusher and increase its working efficiency, other countries once researched and manufactured all kinds of all types of jaw crusher.
West Germany manufactured impact jaw crusher, and Former Soviet Union also manufactured vibrating jaw crusher which can also be called inertia jaw crusher. They all relied on the vibration impact of movable jaw to crush the materials in order to improve the performance of the crushing machine.
East Germany manufactured a simple pendulum double-chamber jaw crusher, and the USA once researched a compound pendulum jaw crusher, and their feature is to make the interval work become continuous work, thus increasing the working efficiency of the crushing equipment.
At the end of 1996, PSS1580 Jaw Crusher with Double Cavity and Double Movable Jaw Plates was put into use in this plant and its capacity was raised to 160000t/a. The production practice shows that with the merits of PSS1580 Jaw Crusher, the feeding size of grinding mills is reduced from 20mm to 10mm. Perishing method, lowering the feeding size of grinding mills, is an effective way to improve the productivity of grinding mills and lower its power consumption. It has obvious economic benefit to substitute crushing for grinding.
Driving the two blocks thrust plate to do reciprocating motion, thereby pushing the movable jaw to do reciprocating movement, achieve crushing and discharging. The crusher uses the crank double linkage mechanism, while the movable jaw by great crushing force, and the eccentric shaft and the connecting rod is less force, so the industry is made more mainframe and midrange, used for crushing hard material. In addition, the crusher, jaw on each point of the movement trajectory is the mandrel as the center of the arc, arc radius equal to the point and axis distance, small lower end of upper arc, arc, crushing efficiency is low, the crushing ratio I General 3-6. Because the track is simple, so is simple swing jaw crusher.
Former Soviet Union once manufactured a double-movable-jaw jaw crusher. Double Movable Jaw Plates has many advantages, such as smaller volume, less weight, higher capacity, smaller particle size, easy to maintenance, operating safely and reliably and so on. It has an enormous patent market and is hopeful to take the place of the traditional Jaw Crusher.As the professional manufacturer of complete sets of mining machinery, such as sand maker,classifiers, Henan Hongxing is always doing the best in products and service.
