In order to meet requirement of all ammunition factory at present, research explosive broken technology of TNT, B-detonator, THL-detonator for adapt ammunition-factory’s demand. The equipment adopts third-class roller broken technology to realize safe and automatic broken of explosive. The equipment changes that wood-sinker knock on explosive to make it into fragmentation, and improve the self-safe degree of production, and change work environment better. It also improves work efficiency, realizes explosive recall and recycle and reduces produce cost.
