The Thermo Scientific Ramsey Medium Range Weigh Feeder offers accurate weigh feeding of light materials at low feed rates. Its unique design and construction features provide a consistent flow of materials, offer increased sensitivity for more accurate weighing of the lightest materials, and permit quick and easy cleaning and maintenance.

Precise feeding of process materials is often critical to maintaining product quality. A feeder that weighs accurately and reliably can reduce material waste, help maintain blend consistency and increase profits.

We have over 35 years of experience designing and manufacturing weigh belt feeders. Every feeder is designed to meet the specific needs of the application. We work closely with our customers to ensure that each system meets their expectations for performance and dependability.

The Thermo Scientific Ramsey Medium capacity weigh belt feeder is designed for weigh feeding applications with low feed rates and light belt loading requirements. It accommodates flow rates as low as 54 kg per hour up to 25000 kg per hour, and belt loadings of 3 kg/m to 30 kg/m .

Theory of Operation

Material is fed onto the feeder through an inlet feed section equipped with a manually adjustable vertical slide gate to control material height. The scale carriage/weighbridge assembly measures the gravitational force of the material and converts this force measurement into an electrical output signal proportional to belt loading.

A digital speed sensor continuously monitors the belt speed.
The microprocessor-based electronics integrate the two signals to produce and display a true rate and a total weight fed. The electronics also provide an output signal for control and monitoring purposes.

Features and Benefits

The RamseyTM Model Medium capacity weigh belt feeder, with its innovative design and unique features, was developed to meet the high standards and greater accuracy demands of today’s food, chemical and process industries.

  • Unique Head Pulley Configuration: The pulley configuration on the discharge end of the belt provides an even, consistent flow of difficult process materials off of the belt.
  • Tail Drive Arrangement: This reduces carry-side belt tensions to provide greater sensitivity for more accurate weighing of the lightest materials.
  • Cantilever Design: This feature permits quick and easy belt removal for cleaning and maintenance.
  • Dual Load Cell Scale: Dual load cells enable a higher degree of response to material weight variations.
  • Stainless Steel Construction: Stainless steel provides improved corrosion resistance and wash down capabilities.
