Acrison Model 101-0 single-auger feeder — Model 101-0 single-auger feeder

Meter a controlled volume of free-flowing granules or pellets.

Is the material free flowing, with sufficiently consistent bulk density?

Acrison Models 101 and 130 are single-auger volumetric feeders for dry granular and pelletized ingredients. The selected auger and drive speed set the volume delivered. They provide a straightforward starting point when the material flows reliably and the process does not require continuous weight feedback.

Typical application
Meter plastic masterbatch pellets or another suitable free-flowing ingredient into a process.

Also known as: Volumetric screw feeders, single-auger feeders, dry ingredient dosers.

What this feeder can help you do

Set a repeatable delivery rate

Select the auger and operating speed around the required volumetric output.

Keep the metering arrangement simple

A single-auger mechanism meters suitable free-flowing dry solids.

Plan for product changes

Self-emptying construction and optional quick disconnects support the cleanout discussion.

How the feeding process works

Supply the feed chamber

The hopper supplies a suitable free-flowing material to the metering auger.

Turn the selected auger

A variable-speed gearmotor rotates the auger to deliver the selected volume.

Check the delivered output

Establish the rate with the actual material and recheck when its properties or process conditions change.

Materials & industries to review

Plastics & masterbatch

Pellets and granular colour concentrates. Acrison demonstrates Model 101 feeding plastic and masterbatch pellets.

Food & feed granules

Suitable dry, free-flowing ingredients. Review bulk density, moisture, fragility, and cleanout needs before selection.

Industrial granular products

Dry granular chemicals and other suitable free-flowing solids. Confirm compatibility, particle dimensions, and wear.

Exact-model material demonstration

Material handling in practice

Describe the product as it reaches the feeder, including pellet shape, size distribution, moisture, and bulk-density variation. Confirm whether your setpoint is a volume per hour or a mass per hour, then establish the usable auger and speed range in a material trial.

Manufacturer application history

When a different volumetric mechanism is the better fit

In Acrison’s Cadbury case history, the requirement involved variable-density powder and a hopper that compacted the ingredients. The project used a Model 105 double-concentric-auger feeder after material trials. It is a useful reminder to choose the metering mechanism around the material, rather than assuming a 101/130 single auger suits every powder.

Configuration & selection

Featured design: Models 101 and 130 Series: single-auger volumetric metering.
Material fit: Free-flowing granules or pellets. The 130 literature specifically excludes cohesive, hygroscopic, or pressure-sensitive material from its typical design duty.
Rate selection: Model size, auger, speed range, and the actual product determine usable output. Published series-wide ranges do not describe every individual feeder.
Drive & contact parts: Variable-speed AC or DC gearmotor arrangements and stainless steel product-contact construction. Confirm exact grades and seals in the quotation.
Cleanout: Self-emptying design; quick-disconnect and sanitary construction are available for review.

Options to discuss with RTS

Model size and interchangeable metering auger
Integral hopper size or flanged feed-chamber arrangement
AC or DC drive and control modes
Quick-disconnect construction
Sanitary contact construction and finishes
Application-specific materials, temperature, or pressure construction

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

What happens if bulk density changes?

At the same volumetric output, a change in bulk density changes the mass delivered. If the process requires controlled kg/h despite density variation, compare loss-in-weight or weighbelt feeding and validate the required performance with the actual material.

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.
