Model S & SB Weigh Belts
Thayer Scale’s Model S & SB weigh belts offer simplified construction and calibration.
Thayer Scale’s Model S & SB weigh belt feeders adapt well to existing vibratory, screw or belt conveyor installations where weight measurement and/or flow control is desired. On new installations, the combination of a suitable pre-feeder and type S or SB unit often meets both cost and material handling requirements.
Depending on material being handled, pre-feeder can be screw, rotary, belt, vibratory or pinch valve. Screw, rotary or pinch valve pre-feeders are normally used with fluid powders, while belt and vibratory pre-feeders are used with granular or fibrous materials.
These weigh belt feeder models are available in carbon or stainless steel construction and in open or enclosed styles. On enclosed feeders, all functional components are located outside of the enclosure.
Industry Applications
Suitable for multiple specialty applications.
- Construction: Rock wool
- Metals & Rubber: Aluminum chips, hot rubber extrusion
- Food: Ice, Cheese Curd, Sugar, Potatoes
- Mining & Aggregates: Sand, Petroleum Coke
- Recycling: glass cullet

Core Technologies
⚖️ FMSS™ Force Measurement Suspension System
The scale provides for complete mass counterbalancing of the dead load of the conveyor assembly, permitting the load sensor to react only to the net material load.
Thayer Scale Instrumentation
Can be supplied with Thayer Scale’s instrumentation package enabling the system to operate as either a process stream integrator or as a process controller.
🌀 Flexible Drive Systems
The unique design of the Thayer S & SB feeders allows for a wide range of drive and belt configurations not normally suited to weigh belt feeders (positive drive, wire mesh, modular, cleated, profiled or other high-tension belts)
📏 Tail Pulley Mounted Speed Encoder
Measures the true speed of the belt via rotation of the idling pulley, belt slippage or breakage is immediately detected because the idling pulley stops rotating.
📐 Customizable Engineered Options
Multiple transmission options that utilize commercially available components, two belt cleaner options to remove fines or residue and maintain zero measurement stability.
🔧 Optional Automated Test Weight Positioning System
Automatic test weight positioning mechanically exercises the scale for safe, verifiable calibrations which can be completed automatically from a supervisory control system or manually initiated by an operator.
🛡️Full-Length Adjustable Skirt Boards
Tapered and flared for product containment, preventing spillage and particle jamming.
