ABSTRACT
With the development trend of Chinese coal and metal mine towards the upsizing, the half continuous mining technology featuring a large-scale crushing station as the key equipment has been used widely. Considering the main machine of the large-scale crushing station always depend on products from the developed countries such as European counties and USA, it is imperative to develop a new high-efficiency and energy saving crushing equipment to substitute imported equipment and meet the needs for the domestic large-scale mine.
China's large-scale opencast mine may shift crusher station began in the 1990s. Broken only meet its performance than the soft coal and stripping of the broken, use was limited, can not meet the requirements of the use of mines. This thesis research and the efficient hammer crusher because of its unique structure on the merits, making production capacity, high hardness broken, broken than large, uniform size markers, too small to smash. Thus, the crusher is a broad future development of efficient broken equipment.
The layout having accomplished the complete machine external form putting the dyadic spirit face hammer crusher together designs the main body of a book, application and operating principle having introduced the type crusher of all kinds's, at present domestic crusher current situation and developing trend and, adopt the one-level cone tooth to reduce the speed combining with the broken ability and request; Condition having set forth a gear wheel becoming invalid; Hydraulic coincidence the implement operating principle; The coal moisture content breaks effect in process to being broken; Impact of the coal size over broken effect; Break the machinery be maintained to pieces.
