DetailsDuring choke feeding the crushing action takes place between the jaw plates and particles, as well as by inter-particle compression. Choke feeding necessarily produces more fines and requires careful feed control. For mineral liberation, choked feeding is desirable.
DetailsBecause of that reason, the choke feeding intensity undertakes the role of crushing efficiency. Since there is no standard approach for the evaluation of choke feeding intensity for industrial jaw crushers (Fig. 1), it is required to figure out the mechanism of choke feeding as a function of feeding size and quantity.
