A portable rock crusher could be at its most effective condition when the capacity is arranged at 80-400t/h, for its space-limited frame for containing and supporting other equipment pulls certain standard on the fixed crusher used with it, which indicates that a fixed crusher is not fitting for the carrying frame if its biggest capacity is under 80t/h or above 400t/h.A small or mini fixed crusher cannot take too much more of vibration and friction, while a big one fails to fit in the frame of a portable rock crusher.Therefore, if some projects such as coal mining, gold mining are located in the terrible environment, a 80-400t/h portable rock crusher equipment will be the best choice because of its flexibility and great efficiency.
