Acrison Model 203-105Z weighbelt feeder with integral prefeeder — Model 203-105Z weighbelt feeder with integral prefeeder

Control a continuous dry-solids stream with a weighed belt and integral prefeeder.

Would belt weighing suit the material and the way it enters your process?

The Acrison Model 203 combines a variable-output prefeeder with a scale-mounted, constant-speed weigh belt. The weighing system measures the product on the belt and the controller adjusts the prefeeder output to match the selected mass-flow rate. It is a gravimetric method that measures material on a belt rather than loss of weight from a supply hopper.

Typical application
Meter a continuous ingredient stream where a suitable prefeeder can deliver the material consistently onto the belt.

Also known as: Weigh belt feeders, belt weigh feeders, gravimetric belt feeders, continuous weigh feeders.

What this feeder can help you do

Start with controlled material delivery

The integral prefeeder supplies the belt and helps establish a consistent initial flow.

Use weight feedback on the belt

The weighing and control system refines delivery against the selected mass-flow setpoint.

Choose a suitable prefeeder

Review the correct mechanism for the product rather than relying on the belt to solve upstream flow problems.

How the feeding process works

Feed onto the belt

The selected integral prefeeder meters material onto the weigh belt.

Weigh the material in transit

The scale-mounted belt runs at constant speed while the weighing system senses the product load.

Correct the prefeeder output

The controller adjusts the variable-speed prefeeder to bring the weighed output toward the selected feed rate.

Materials & industries to review

Food ingredients & flakes

Review suitable dry ingredients, including difficult-handling products, with the appropriate prefeeder and cleanout arrangement.

Plastics & granular solids

Compare product loading, carryback, discharge behaviour, and the required rate range with the belt arrangement.

Chemicals & mineral products

Discuss wear, adhesion, dust, temperature, and containment. Final suitability depends on both the belt and the prefeeder.

Prefeeder application demonstration

See the 105Z prefeeder handling dried potato flakes

This official Acrison demonstration shows a Model 105Z metering dried potato flakes. The 105Z is the prefeeder type shown on the 203-105Z configuration. The clip illustrates material handling; it does not show the complete weighbelt assembly or its feedback control.

Material handling in practice

Review how the material loads the belt, how it releases at discharge, and what could remain on the belt after discharge. Include upstream flow control, dust enclosure, service access, cleaning, and the full required rate range in the application review.

Configuration & selection

Featured design: Model 203 weighbelt feeder with an integral variable-output prefeeder and a constant-speed, scale-mounted belt.
Rate-control method: Weight feedback adjusts the prefeeder output. The selected design is not described as a variable-belt-speed control system.
Published family capacity: 60 to 48,000 lb/h across the Model 203 range, based on material at 40 lb/ft³. The selected size and actual material determine usable capacity.
Published feed range: 20:1 from the maximum designed output of the specific model or size; validate minimum-rate performance for the application.
Related arrangement: Bulletin 723 also covers Model 203B weigh-auger feeders. That is a separate configuration, not the same belt machine.

Options to discuss with RTS

High-temperature arrangements
Stainless steel construction with component-specific exceptions
Hazardous-area electrical construction and plant-control integration

Send a material sample description, minimum and maximum feed rates, bulk-density range, particle sizes, moisture, and a process sketch. Include the required accuracy, measurement interval, upstream refill method, cleaning needs, and available space.

Questions to settle before selection

How does the Model 203 differ from a loss-in-weight feeder?

The 203 measures material travelling on its belt and corrects the prefeeder output. A loss-in-weight system measures the reduction in weight of a supplied hopper and feeder over time. Compare process layout, material behaviour, refill arrangements, cleaning, and the required performance before choosing.

Can we establish performance with our actual material?

Acrison offers witnessed equipment demonstrations and material testing. Agree on the feed-rate range, sample collection method, test duration, and acceptance criteria so the results reflect the intended process.

What should we include in the feeder review?

Consider the hopper, metering mechanism, weighing method where applicable, refill supply, controls, discharge connection, dust management, and access for cleaning. Identify which equipment and interfaces need to be included in the quotation.
