Development and improvement of the jaw crusher has made some achievements in recent decades in the development process. Machinery and equipment used in the design of negative support zero suspension, hyperboloid cavity having a structural feature type, processing power and equipment efficiency are high. But to a certain extent, there are still disadvantages of jaw crusher. As a common crusher equipment, jaw crusher is the necessary equipment for crushing material its unique properties is widely used, the user has welcomed jaw crusher has broad application, but with defective equipment gradually revealed, jaw crusher has some corresponding disadvantages, such as the consumption of large jaw crusher, wear faster and so on.
First, the choice of steel. Steel selection is jaw crusher production materials, broken equipment wear is the most important requirement, jaw crusher wear parts are mainly jaws and shields, high manganese steel jaw plate adopt high quality alloy during casting the improvement of hardness and resistance material by adjusting the ratio of carbon steel. Second, the structure of the jaw crusher. Including the whole shape, appearance and component assembly design optimization components. Jaw crusher can be cast and welded chassis, you can also use other means such as a bolt adapter, so the use of jaw crusher in the field of adaptive capacity have been greatly improved. Optimized cavity shape, that changes the shape of the tooth plate section, a more rational crushing chamber curve, so that the feed and discharge to give the best fit to change the suspension height, the height of the suspension being reduced to zero or even negative suspension order increasing the level of the lower end of the movable jaw stroke.
Third, to improve the conservation system. Jaw crusher as the first breaking strength of a larger work, routine maintenance and maintenance once can not keep up, to a large extent will increase equipment wear and shorten the life of the jaw crusher. Currently degree jaw crusher plus circulation path and lubricating oil cooling system can effectively reduce equipment wear and reduce maintenance and maintenance costs of daily production.
