Jaw crushers. Jaw crushers were invented in 19 th century and are mainly used as primary crushers to produce material that can be transported by belt conveyors to the next crushing stages. The crushing process takes place between a fixed and a moving jaw. Shaft rotation, along with the toggle plate, causes a compressive action of the moving jaw.
WhatsApp: +86 18838072829The breakage and liberation of minerals are the key to fluidized mining for minerals. In the ball milling process, steel balls function as not only a grinding action implementer but also energy carrier to determine the breakage behavior of ores and the production capacity of the mill.
