Double Roll Crusher Henan Deya Machinery Co., Ltd.
Double roll crusher (also called twin roll crusher) is composed of two cylindrical rollers as the main working mechanism (Figure 1). When working, the two round rollers rotate in opposite directions, and the material (ore) is crushed by the friction between the rollers, which rolls the material into the crushing cavity formed by the two rollers.A toothed double-roll crusher (referred to hereafter For the structure of staggered-tooth-roll (Fig. 3 c), the first and third crushing rings on Optimisation of a circularly vibrating screen based on DEM simulation and Taguchi orthogonal experimental design.
