Some Ameri company manufactured oblique jaw crusher which was unique in structure. The toggle plate is supported on the top of movable jaw, which is connected with the dead eye part through the bilateral plate and there is an eccentric shaft installed in it. In this way, when the eccentric shaft rotates, it will drives the moable jaw to move along an ideal track so as to reduce the wear and tear of th lining plate.

Jaw Crusher

The movement of moable jaw is helpful to materials feeding. The upper part of fixed jaw is hung on the main bearing and the lower part is suppported by the pressure lever and tightened by the spring. This machine changes the material discharging mouth through adjusting the rear gasket of the pressure lever. The crusher has relatively high rotary speed. Compared with crushers with the same specifications, it has higher output and higher crushing ratio.

On the basis of this series of product, the experts of crusher equipment in our country developed jaw crusher whose biggest specification is 900×1200 and 1200×1500. The biggest feature of this crusher is short so that it is most suitable to work under the shaft or on mobile crusher.

The research and development of jaw crusher in our country has achieved great breakthroughs since the 1980s. A famous crusher expert analyzed the gnaw angle design concept of traditional jaw crusher and came up with movable gnaw angle responding to the movement characteristics of singe toggle jaw crusher and designed highly efficient and low-abrisive single toggle particle crusher whose toggle plate is put on the bottom of the crusher and whose crushing chamber is a curving shape, which caused a sensation in the domestic mining machine market. Compared with other jaw crushers, on the same working conditions, this crusher improves the processing amount by 20一50% and the service life of jaw plate is prolonged by one time.

In 1995, the experts organized by China Non-ferrous Metal Industry Company appraised and passed PED750×1060 short removable jaw crusher. This machine has many advantages such as stable performance, high production ability, little malfunction, low noises and little dust. It is a new type jaw crusher that is able to work in special circumstances such as in the pit, so that it makes up for the gap in the domestic crusher industry and provides new product for the upgrading of the crusher industry in our country.
