Feeders control the rate of rock entering primary crushers, and choosing the wrong type causes surging, blockages or premature wear. Vibrating feeders suit medium, free-flowing material while apron feeders handle heavy, large, sticky blocky ore.

Vibrating feeders are lighter, lower cost and good for pre-screening fine soil ahead of the jaw. Apron feeders use heavy steel pans and stand up to massive boulders and high impact loads at mine faces.

SMP engineers match feeder type based on maximum lump size, bulk density and material stickiness. A primary apron feeder paired with pre-screening can protect the jaw from shock loads.

Selecting the proper feeder stabilizes primary crushing feed rate, reduces choke risks and extends jaw plate service life.
