摘要：By the example of justification of the design parameters of the fixed jaw body of the jaw crusher, the methods have been developed for choosing the optimal parameters according to the strength condition under restrictions on its mass. The practical value of the work is in development of the recommendations for designing the fixed jaw body, based on the criterion of minimum mass for the set tensile strength. It is shown that the use of the proposed recommendations allows to reduce the metal consumption of the jaw by 170 – 200 %.
