Thayer Scale’s state-of-the-art material test center enables our customers to evaluate trial runs on volumetric and gravimetric feeding equipment, and to benefit from our engineering team’s deep technical expertise. At the test center, a dedicated technician helps customers replicate industrial processing conditions to assess and resolve any material handling difficulties. Our test center is particularly useful for clients who are (1) new to volumetric or gravimetric feeders, (2) verifying feeder performance and/or accuracy, (3) using new materials, or (4) consistently experiencing material feeding problems.

Dry-Particulate Feeder Testing

A 2,000 square foot (186m2) test center dedicated to dry particulate feeders resides within our manufacturing facility.

Benefits include:

  • Product application and performance testing with user-supplied materials
  • High ceilings to accommodate large-capacity supply bins and automated material handling devices

Engineering Resources

Thayer Scale’s team of material application engineers helps clients:

Analyze material handling characteristics

Select durable and cost-efficient feeder and instrumentation applications

Define and calculate material properties, including:

  • Material form
  • Particle size
  • Bulk density

  • Optimal feeder settings (e.g., angle of repose, hopper wall angle)

Gravimetric and Volumetric Feeders

The test center provides access to Thayer Scale gravimetric and volumetric feeders.

Clients may experiment with:

  • Loss-in-weight feeders with auger and vibratory dischargers
  • Weigh belt feeders
  • A range of specialized and proprietary flow aids

Verified Material Testing

Material test data helps users verify accuracy and assess equipment performance; video recording of all testing is available at no charge, upon request.

Thayer Scale’s testing facility enables:

  • Flow rates up to 1,000 pounds/hour (~450 kilograms/hour) with automated catch sampling
  • Flow rates of up to 5,000 pounds/hour (~2,270 kilograms/hour) with manual sampling
  • Documented test-result reports available through our data acquisition system
