About jaw crusher
1840s, North American gold mining boom of the jaw crusher has a great role in promoting development.
Limestone crushers. Mid-19th century, various types of jaw crushers have been developed and received a wide range of applications. The last century, the world has 70 different structures of the jaw crusher to obtain a patent.
1858 Eric Blake (El.Blake) to obtain patents, create elbows plate jaw crusher, the most commonly used is the Blake jaw crusher jaw crusher and a more modern single-bracket made palate crusher. Jaw Crusher is one of the biggest weaknesses of their work in a cycle, only half the time to work.
Since the 1980s, China jaw crusher development and improvement achieved some results. As my broken expert Professor Wang Hongxun Master and his students Dingpei Hong cited "dynamic nip angle" concept, the development GXPE series of deep cavity jaw crusher, then caused a certain sensation in the country. The machine with the same specifications crusher compared to the same working conditions, capacity can be increased by 20% to 25%, life expectancy can be increased tooth plate 1-2 times. The machine uses negative support zero suspension, with double-curved cavity.
The second generation GXPE250 × 400 in the first generation of negative support on the basis of a comprehensive improvements, increased crushing ratio,
Stone Crushers, reduced product size, maximum feed particle size of 220mm, hours of production 5 ~ 16t, nesting population adjustment range of 10 ~ 40mm, feed compressive strength less than 300MPa.
PEY4060 Insurance hydraulic jaw crusher, the hydraulic cylinder for the overload protection device is supported, is hoisted, deep crushing chamber. The aircraft maximum feed particle size of 340mm, discharge adjustment in the 30 ~ 100mm, the production capacity of 10 ~ 40t / h.
Beijing Research Institute of Mining and Shanghai Linyun Liang, who more than spiritual - Watson Machinery Co., Ltd. to develop a low PED detachable jaw crusher. The machine is suitable for underground work under special conditions of the new jaw crusher. The height of mechanical lower jaw position is low, the fixed jaw is located between the movable jaw and the eccentric shaft.
More spiritual - Watson Machinery Co., Ltd. Rong Jihua senior years of experience set, designed the nation's largest 1200 × 1500 Jaw Crusher.
2.2 new jaw crusher
Its working principle is: the material into the hopper into the machine, by the separation mechanism will spread into the surrounding material cutting. The V-belt drive motor eccentric shaft, jaw moving up and down movement to crush the material to reach a certain size into the rotary chamber. The material in the cavity by rotating the grinding rotor and fixed the broken jaw, broken material from the hopper discharge. Machine bolts and subtraction through the spacer adjustable elastic material out of granularity. Using circular feeding, feeding a large range of machines than the broken jaw, cutting speed and not blocked. With the same specifications jaw broken machine compared to its production capacity, small particle size,
Stone Crusher Plant, crushing ratio, the aircraft has been officially produced.
