IMPACT CRUSHING

LA TRITURACION POR IMPACTO

Details are given of the basic principles which led to the construction and use of a new impact crusher for hard rock. The operational costs of the machine are apportioned into partial costs and presented in the form of a mathematical model. The different methods adopted to reduce the cost of wear are described among others, the adequate distribution of crushing bars, the shape and spacing of impact devices by applying Ehrhardt formulae transformed into proportional ratios. Conclusions are drawn regarding the design of impact crushers for hard rock and their practical use. (TRRL)
