The high-strength crushing principles of impact crusher is that the materials may experience the second time bounce after the first impact force produced by high-speed rotation blow bar of the rotor, and then it will achieve the capacity of 120-260t/h. Over the years, the crushing equipment of mining industry has been constantly making replacements and technical innovations about the structure. In order to increase the impact force of blow bar, the designers develop the impact hammer crusher, which brings advantages of both impact crusher and hammer crusher together and becomes the new dominant force of crushing equipment. After market research, it is found that the development space of impact hammer crusher is mainly reflected in the following aspects.
Firstly, the appearance of impact hammer crusher is a great reform about structure and function of traditional impact crusher. On the basis of ensuring the existed performance of impact crusher, it expands the production capacity and strengths crushing effects. As the technical parameters and production of impact hammer crusher is concerned, it is more focus on the fine crushing, that is the fine processing of materials we advocate.
Secondly, it can be seen that the impact hammer crusher has greatly improved the stability of the equipment; the lubrication device and the bearings of large inertial devices have saved maintenance time to a great degree. The new single crusher is the improvement of crushing process in an intensive way. At present, the impact hammer crusher has been successfully applied from mining industry into metallurgy, refractory, chemicals, ceramics industry.
Lastly, the technical innovation of impact hammer crusher reflects the latest development directions of mining equipment and constantly makes adjustment towards large-scale, high-performance and environment-friendly. The domestic dominant model of economic development is to strengthen the full use of existing resources, maximum the value of China’s mining industry to drive the development of national economy, meanwhile, stick to the strategy of sustainable development and develop mineral processing equipment of low energy consumption and low pollution. This is the demand of national economy development and also the ultimate goal of crushing device structure transformation.
