With the develope of economic t, mining machinery is in rapid development. Mining machine equipment not only in domestic infrastructure construction and mine construction plays a huge role,but also exported to foreign countries, in the international market also plays an important role. At the same time, mining machinery industry manufacturing system already has a large-scale. In fact, from the early start to Hongji Machinery has been to explore their own core technologies and innovative ideas, continuous walking in the forefront of the international technical community crusher, crushing equipment in the country champion, is rushed into the foreign market brand. Hongji mining machinery has developed new vertical shaft impact crusher and jaw crusher machine, which proved Hongji can live longer in mining machine industry.Jaw crusher is one of the most important machines in mining machinery industry. Jaw crusher is so popular just because it’s superior performance and simple operation. Jaw crusher can broken the high hardness materials easily, and was durable, easy maintenance. So the jaw crusher was deeply favored by domestic and foreign customers. Jaw crusher is divided into large, medium, small 3 kinds according to the size of the feeding port width. And also can divided into simple swing jaw crusher, complex swing jaw crusher and comprehensive swing jaw crusher according to the different ways of flow jaw plate swinging.Along with the fast development of construction and mining industry, jaw crusher is playing more important role in modern society. The distinguished features of jaw crusher are high crushing ratio. Jaw crusher has little requirement for feeding size, the mobility design makes materials get multiple crushing so as to improve the crushing capacity. Hongji jaw crusher can meet the crushing requirement for many enterprises.
