The exploitation and utilization of mineral resources and the sharp increase of the exploitation quantity and the materials need to be crushed in the industries of building material and road pavement makes crushing machine more and more important. Jaw crusher is a crushing machine with pretty wide application.
To reduce the energy consumption of jaw crusher, it is necessary to make improvement and innovation to its structure to optimize its structure and movement locus. The detailed measures are as follows:
(1) Improve the crushing chamber. The commonly adopted deep crushing chamber and small installation angle can increase the crushing ratio of the crushing machine and reduce the abrasion of the spare parts.
(2) Improve the hanging method of the movable jaw and the supporting method of the lining board. Jaw crusher uses new and wear-resisting materials to reduce the abrasion consumption.
(3) Improve the automatic level of jaw crusher and such technologies as overload protection, automatic adjustment and lubrication can realize the improvement of automatic level.
In addition, the researchers of Hongxing Machinery also research and develop some new types, and they designed a double-chamber jaw crusher. This new jaw crusher is formed by two crushing chambers symmetrically distributed on both sides of the eccentric shaft. On both sides of the movable jaw, there is a movable tooth plate which forms two crushing chambers with the fixed tooth plates. When it works, materials are successively and uninterruptedly crushed in the two crushing chambers. In this way, the crushing granularity is small, the electric motor can be fully used and the production capacity can be greatly improved.
