The Development Of Jaw Crusher Machine

jaw crusher

Jaw crusher in the mining industry use is very extensive, then jaw type crushing machine’s history is what kind of jaw crusher and experience what kind of regime change? Below detailed announced jaw type crushing machine development.
Crusher development has played a great role in promoting. 1850s, people developed a variety of types of jaw crusher, and in a wide range of use. By the end of the last century, the jaw crusher has made 70 patents in the world, that is, there are more than 70 kinds of different structures in the world.
1858 Eli Blake made double elbow plate jaw crusher patent, the current commonly used jaw crusher is designed by Blake. Another commonly used jaw crusher is a single toggle jaw crusher, designed by modern designers. Grant and his students Ding Peihong master, they reference the concept “dynamic meshing angle”, developed gxpe series deep cavity jaw crusher. This broken jaw compared with the same kinds of specifications of the crusher, under the same conditions, processing capacity increases by 20% ~ 50%, tooth plate life expectancy increased by 1 to 2 times, greatly extend the service life of the jaw. The jaw crusher itself have movable jaw plate and the fixed jaw plate, run, fixed jaw plate, jaw plate to fixed jaw plate near and away from, stones can therefore is crushing and discharging.
The second generation GXPE250 * 400 negative support on the basis of the first generation were overall improvement, increase the crushing ratio and reduce the product size, maximum particle size is 220mm, output per hour for 5 ~ 16t, discharging mouth of the adjustment range of 10 ~ 40mm, to small material compressive strength of 300 MPa. PEY4060 hydraulic safety jaw crusher, with hydraulic cylinder as overload protection device, is supported, is hanging, deep crushing cavity. The maximum feeding size of the machine is 340mm, and the material discharging is adjusted between 30 and 100mm, and the production capacity is 10 ~ 40t / h.
The new jaw crusher is the emergence of earlier broken equipment, because of its structure simple, solid, reliable, easy to maintain and repair and production and construction cost is low. Thus, until now still widely in metallurgy, chemical industry, building materials, electricity, transportation and other industrial sectors for compressive strength in 147 ~ 245MPa all kinds of ores and rocks of coarse, medium and fine crushing. In recent years, I plant to meet the high strength, high hardness micro carbon ferrochrome needs on the fracture and fragmentation of metallurgy, mining, construction and other industrial sectors, specially developed strong jaw crusher.
