Uniform, Non-Surging Feeder

Wyssmont's Multiple Screw Feeder features a series of carefully fabricated, continuously welded helicoids operating in parallel to feed material from a hopper without surging and bridging commonly experienced in ordinary screw feeders and conveyors. While most screw feeders and conveyors are known for surging and non-uniform feeding, Wyssmont's Multiple Screw Feeder is specially designed to discharge with minimum surging. The variable pitch of the screw flights uniformly draws material from the hopper and resists segregation of the product.

Special fabrication and design can assure minimum breakage of crystals and pellets where this is specified. In sealed systems, the feeder will create its own seal under appropriate conditions.

Live-Bottom Bin

With an appropriately designed hopper above the screws, the unit becomes a live-bottom bin. It resists bridging and gently handles the material.

The Wyssmont Multiple Screw Feeder can be supplied in stainless steel, carbon steel, or special alloys. The housing can be jacketed to cool or warm the feed material.
