How to combine ore crushing production line more efficiently

Fixed ore crushing production line configuration 1. Feeder + jaw breakage + counterattack breakage + vibrating screen + conveyor belt This is a common sand crushing production line, jaw fracture as the primary fracture, all kinds of ore materials for crushing and processing into the particle size required for the second fracture, and counterattack as the second fracture link, not only can achieve the fine effect, but also can achieve the function of shaping and modification, so that the treated material particle size is uniform, very good grain type
