LWF-8-V Vibratory Feeder With Spiralator™
Low rate feeder up to 3,250 lbs/hr @ 50 pcf material.
- Unique agitator design assures conditioned flow of caking and cohesive powders, interlocking particles, fibers and flakes.
- Permits use of vibratory feeder for a wide range of materials that cannot typically be handled using conventional feeders.
- Built to survive, with simple, reliable construction. Patented design with high accuracy weight sensing.
- Precise second-to-second control with exclusive "EFT" Tracking.
Prevents material bridging and arch formation
The agitator component of the Spiralator™ Feeder is a motor driven stainless steel spiral, manufactured to conform closely to the 70° walls of a mass flow supply hopper. The spiral does not rotate in the direction which would compact material into the discharge, instead it slowly counter-rotates, to gently and contiuously lift the material closest to the hopper wall. Thus, a stable arch cannot form, effectively neutralizing bridging. The agitator is highly effective, yet slow and gentle to prevent damage to delicate products or stratification of powder blends.
Neutralizes tendency of material to compact under its own weight Material compaction not only contributes to bridge formation, but it also inhibits vibratory tray action, resulting in poor or no flow. Inside the Spiralator Feeder hopper, material is lifted and conditioned by the spiral agitator, to prevent densification and relieve the vibratory tray of the full weight of the material, so that the tray can deliver a uniform stream of product.
Uniform, non-pulsating flow THAYER® Loss of Weight Vibratory Feeders provide an exceptionaly uniform flow of material at very low flow rates. Exceptional turndown range of 50:1 provides greater flexibility than screw feeders, without the problem of pulsating flow from a slow turning screw.
