Therefore, dry particles wedged between level A and level B (Figure ) would leave the crusher at the next reverse movement of the jaw. The maximum size of particle dropping out of the crusher (d MAX) will be determined by the maximum distance set at the bottom between the two plates (L MAX).
· Particle size distribution curves of recycled aggregates from building demolition concrete crushed by jaw and impact crushers. The jaw crusher produced 60% of coarse aggregates in weight, whereas the impact crusher produced 49% coarse aggregates. The proportion of particles finer than mm is around 7–8% weight for both crushing mechanisms.
