Impact crusher is a new high-efficiency crushing equipment, which is characterized by small size, simple structure, large crushing ratio (up to 40), low energy consumption, production capacity, uniform particle size, and selectivethe role of the crushing is a promising device. Its biggest drawback is that the board hammer and the back plate, especially easy to wear, especially the broken rock in the wear and tear is more serious, need for frequent replacement. The emergence of some of the wear-resistant materials, has been applied in a number of metal concentrator.
Overall, the future direction of development at home and abroad crushing equipment is mainly manifested in the following areas:
1. To improve the existing impact crushers structure, improve the ease of maintenance of the impact crusher in hard ore crushing capacity and equipment, mainly concentrated in the plate hammer, the improvement of the rotor structure in order to facilitate the replacement of the board hammerand loaded card; impact rack (broken cavity shape), structural optimization, improve the utilization of ore at a crushing rate and energy.
2. Research and development with high wear and high toughness of the new board hammer material to improve the life of the board hammer, increase productivity.
