Model M-LD Low Density, Light Loading Weigh Belt
With many of Thayer Scale’s M-LD feeders in operation for more than 35 years, we have more experience than any other manufacturer in weighing low density materials.
Thayer Scale’s Model M-LD low-density feeder achieves unparalleled accuracy in weighing bulk materials with densities under 10 lb/ft3. The Model M-LD boasts outstanding performance in over 1,000 installations, setting the standard for low-density bulk material weighing accuracy and ruggedness.
Leveraging instrumentation upgrades for modern-day automation schemes and re-rating of the load or speed-sensing range to accommodate capacity changes, we’ve been able to help manufacturers keep many of our built-to-survive M-LD feeders in operation for over 35 years.
Industry Applications
Suitable for light loading, low-density materials such as flakes, chips and fibers.
- Tobacco (Tobacco, Frozen Tobacco)
- Forest Products (Wood Chips, Saw Dust, Wood Fiber)
- Textiles (Various Fibers)
- Cereals & Snacks (Chips and Flakes)
