Crusher in the use of the process of consumption of the fastest, most prone to problems, the need to replace the parts than those crusher hammer, crusher liner, tooth plate and other wear parts, but also because of this crusher wear parts of the life of the crusher, affecting the crushing of machinery and equipment, so how to effectively increase the service life of these crusher wear parts, which is to be from the two aspects of the considerations, one is in the Selection of wear-resistant parts need to pay attention to the quality of wear-resistant parts, this is the basis, the second is in the use of some of the protective measures that need to be taken in the process, the following global crusher network for the use of how to improve the degree of wear and tear of the tooth plate to improve the service life of the tooth plate of the problem, listed in the 3 points of attention to the measures.

　For the plant to improve the wear of the plate, improve the life of the plate, reduce steel consumption. Many engineers and technicians have done a lot of research work for it; to improve the wear of the toothed plate to improve the life of the toothed plate, the measures are;.

　　1. The traditional compound pendulum jaw crusher eccentric oil device positive suspension is changed to negative suspension, the crusher characteristics should be improved, the life of the tooth plate can be extended by 50%, energy saving 10.5%, output increased by 20%, the weight of the machine can be reduced by 20%.

　　2. The thrust plate of the traditional compound pendulum crusher is changed from 1:oblique type to Bu oblique type, the moving amount of the tooth plate in the direction of the movement of the crushing stroke has a downward component, which is favourable to the crushing of the material, and prompts the material to be discharged downward to reduce the clogging, and the output can be increased by 20% to 40%, and the abrasion of the tooth plate has been improved, and the life of the tooth plate can be increased by 2 to 3 times.

　　3. The single moving collar of the traditional compound swing collar crusher is changed to double moving collars, so that the relative motion in the longitudinal direction between the two moving collars is close to zero, which eliminates the relative motion in the longitudinal direction between the toothed boards in terms of the characteristics of the mechanism movement, and reduces the wear of the toothed boards, so that the service life of the toothed boards can be prolonged by more than 3 times, and the economic benefits brought about by this are very considerable.
