A lined, heavy-duty vibrating feeder below the crusher can eliminate belt wear from rebar or dowel or tie bar damage. If present beneath the crusher, this deflector plate can keep tramp metal from degrading the conveyor belt. That way, the feeder below the crusher – not the belt – absorbs impact of rebar dropping through the crusher.

Jaw Crushers; Cone Crushers; Typically, the initial crushing stage is completed using either gyratory crushers or jaw crushers. It is often the case that there will be only one crusher installed, and this will be referred to as the primary crusher. Cone crushers are more often used for 2nd, 3rd & 4th stage crushing steps (although not always).
