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.
Vibratory feeders can be classified according to their drive unit, method of applying vibration to the trough, and generated reaction to the supporting structures. In selecting a vibratory feeder, it is important to know the distinction between these categories. For example, it is not enough to specify only brute force vibratory feeders.

A primary crusher is a machine that breaks down large rocks and stones into smaller particles for further processing. It is the first stage in the crushing process and is essential in the mining and construction industry. The primary crusher's function is to reduce the size of the rock or stone for easier handling and transportation.
Critical customers have two more choices for more reliable service where two primary feeds are available. Primary selective and secondary selective schemes both are normally fed from one circuit (see Figure 5 above). So, the circuits are still radial. In the event of a fault on the primary circuit, the service is switched to the backup circuit.
