Jaw Crusher Development History

1840s , the North American gold mining boom of jaw crusher (jaw crusher) has a great role in promoting development . The mid-19th century , many types of jaw crusher developed out and get a wide range of applications . The last century , the world has more than 70 kinds of different structures made of jaw crusher patent .

1858 Eric . Blake (El.Blake) patented manufacturing elbows plate jaw crusher , now the most commonly used is a Blake jaw crusher jaw crusher and single- toggle plate more recent manufacture jaw crusher . One of the biggest weaknesses of jaw crusher is that they work only half the time in a work cycle.

Since the 1980s, the development and improvement of jaw crusher has made some achievements. As our broken expert Professor Wang Hongxun master and his student Dingpei Hong cited the concept of " dynamic nip angle " , the development GXPE series deep cavity jaw crusher , was in the country caused some stir. Compared with the same machine specifications crusher under the same working conditions, the treatment capacity can be increased by 20% - 25% , of the tooth plate life can be increased by 1 - 2 times. The machine uses a negative zero support suspension, with double curved cavity are because the crusher is named according to their works . Jaw crusher jaw itself is moving and static jaw , work , static fixed jaw plate , movable jaw plate driven by the rod and shaft , or move closer to the stationary jaw separation, stones from the top down into the static jaw plate and moving jaw plate angle along Queen or out, in the movement of the large stones smashed. This principle is like a crocodile chewing food , adjust the angle of the upper and lower jaw to crush food , and then through the teeth grinding , and finally into the abdominal cavity. Unfortunately, despite the clever humans , but not entirely the crocodile swallowed food whole process all analog out, because crocodile swallowed during rough times not only squeezed broken , there grinding process, jaw crusher is just taking its previous section , it can only be used as a rough stone crushing, secondary crushing after had to made out of stones or sand. When can I come out of a machine with both crushing, grinding function , time will be a leap of stone production line.

In the 21st century , as China's mining machinery industry first brand new machine development jaw crusher , has a simple structure , reliable operation, large crushing ratio , uniform particle size of the product , easy maintenance, operating costs and economic characteristics , widely used many areas mining, smelting, building material, highway , railway, water conservancy and chemical industry , etc.
