General Purpose Vibratory Tray Feeders
The broadest material volume range—enabled by Thayer Scale’s proven cable suspension architecture.
Thayer Scale’s family of general purpose vibratory loss-in-weight feeders are powered by our unique cable suspension scale. The patented Thayer Scale Cable Scale is the most rugged and forgiving load cell weighing system available on the market. It can take more physical abuse and tolerate more foundation distortion and deflection than all other known designs.
These feeders have a wide feed range and scale capacity that make them the ideal general purpose vibratory loss-in-weight feeder choice.
Thayer Scale’s vibratory loss-in-weight design features our patented Spiralator® hopper agitation system which consists of a slowly rotating, non-agitating, conical wire-spiral within the hopper that counteracts the material’s tendency to pack and bridge under its own weight. Our vibratory feeders also include a patented vibrating tray insert (available in two designs for non-cohesive pellets or cohesive/adhesive powders).
The combination of this unique material conditioning system and a vibrating pan feeder ensures reliable and gentle handling throughout the entire feeding range.
Industry Applications
Suitable for irregular shapes, larger particles, pellets and powders.
- Metals / Metal Powders: Steel Pellets, Powdered Metal, Alumina
- Minerals / Inorganics: Glass Frit, Glass Batch, Hydrated Lime, Petroleum Coke, Coal Fines, Coke Breeze, Sodium Carbonate, Expanded Vermiculite, Pigment
- Plastics / Synthetic Materials: Nylon, Resin, Fiberglass Strand
- Rubbers / Elastomers: Rubber Pellets, Crumb Rubber, Chloride Pellets
- Food / Organic Powders & Pieces: Chocolate Chunks, Cereal, Corn Starch, Dehydrated Strawberries, Sliced Almonds, Sunflower Seeds, Tobacco Fines

Core Technologies
🌀 Spiralator® Hopper Agitation System
Our slow-speed Spiralator® prevents compaction by continuously lifting dry solids along the hopper wall. It’s ideal for gently conditioning non-compacting materials.
📦 Two Feed Tray Designs
Stainless Steel Tray: For free-flowing pellets, granules, flakes, or fibers. Elastomer Membrane Tray: For cohesive or adhesive powders requiring extra vibration energy to ensure uniform flow.
⚖️ Fully Mass-Counterbalanced Flexure Suspension Platform Scale
Maximizes load cell utilization by measuring only the live load and isolating the material weight signal from vibration, shock, and external forces.
🧩 Load Cell Options for Any Application
Strain Gauge Load Cell: Rugged and accurate, rated 25–500 lbs. with 300% overload protection. LVDT Load Cell: High-resolution, tension-style design ideal for light loading and fine-feed applications and offering unparalleled overload protection at 1000% of rated output.
🧰 Built-In Automatic Test Weight Lifter (ATWL)
Built-in calibration system applies a known test load at the press of a button. Enables quick, verifiable calibration checks without halting production or manual intervention.
Key Benefits
of Thayer Scale’s General Purpose Vibratory Feeders
🎯 Extended Operating Range
Feeds from a few grams per minutes up to 1,000s of pounds/hour.
🌀 Gentle Material Handling
Vibrating pan feeder and unique material conditioning system will not degrade or alter the appearance of delicate or fragile materials – including irregular and larger particles
🧱 Built to Survive
Unlike lightweight designs made for short-term convenience or scale sensitivity, our feeders are engineered for long-term durability, without compromising accuracy.
🔄 Integrated Material Agitation Options
Prevents flow issues like bridging, funnel flow, adhesion, and cohesion for consistent material feeding.
📐 Flexible Mounting Options
Supports floor-mounted, rotating, stationary, wheeled, forklift-based, or suspended installations.
