As this crushing machine has many advantages such as high crushing ratio, every material discharging granularity, little over-crushed material, low energy consumption, low equipment production cost and convenient maintenance and repair, it has been widely applied in many industries of cement, building materials, coal, chemistry, metallurgy and mining. According to the number of the rotors, hammer crusher can be divided into single rotor type and double rotor type, and the former one can be subdivided into reversible type and irreversible type. In Hongxing Machinery, stone crushing machine mainly consists of jaw crusher, impact crusher, cone crusher, hammer crusher, VSI crusher and mobile crusher etc.
The development of hammer crusher in China was very slow before the 1970s, and is fast in recent decade, and it has formed universal medium crushing and fine crushing series and coal medium crushing and fine crushing series with more than ten specifications. The irreversible hammer crusher is generally used for medium crushing, and the reversible hammer crusher is generally used for fine crushing. In addition, one-stage hammer crusher is used for crushing the materials with the granularity of 1900mm such as limestone into 25mm just for once, which simplifies the traditional two or three stage crushing into one crushing , thus saving a lot of infrastructure and production expenditure.
In recent years, the ring hammer crusher which is mainly used for crushing coal also has fast development. This machine is a new crusher with advanced structure with more than ten specifications. However, Chinese mining machinery manufacturing companies have not produce double rotor hammer crusher so far, but only single rotor hammer crusher. The specification type and the representation of hammer crusher are not uniformed, and every manufacturer is different. Generally speaking, it is expressed with its Pinyin alphabet and the diameter D of the rotor and its length L, among which, D refers to the round diameter of the head of the hammer, and L refers to effective working length of the hammer along the axial direction.
