Acrison Dry Solids Feeders

Meter by volume, control the mass flow of an ingredient, or weigh a continuous belt stream. RTS helps match the feeder to your material, rate range and process.

Are you metering by volume, loss of weight, or a weighed belt stream?

Meter by volume

Review a volumetric feeder for suitable free-flowing granules and pellets.

Choose the control method before sizing the feeder

A volumetric feeder meters a volume at a selected speed. A loss-in-weight feeder measures how fast its weight decreases as material is discharged. A weighbelt feeder is also gravimetric. The Acrison Model 203 uses a weighed belt and adjusts its integral prefeeder. The material and the required feed-rate range guide the choice.

Acrison Model 101-0 single-auger feeder

Volumetric Feeders

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

Example: 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.

Acrison Model 407X-170-1 loss-in-weight feeder

Gravimetric Feeders

Control ingredient mass flow using loss-in-weight measurement.

Example: Control an additive or ingredient feed in kg/h, or deliver a defined batch quantity.

Also known as: Loss-in-weight feeders, weight-loss weigh feeders, LIW feeders, gravimetric dosing systems.

Acrison Model 203-105Z weighbelt feeder with integral prefeeder

Weighbelt Feeders

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

Example: 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.

How the equipment fits into your process

From storage into the feeder

Tell us what fills the hopper, the available headroom, and how the feeder can be replenished during operation.

At the ingredient addition point

Define the continuous rate range or minimum and maximum batch weights, along with how you will measure acceptable accuracy.

Before mixing or blending

Identify what receives the feed, the discharge pressure or temperature, and the controls that coordinate ingredient delivery.

Questions to help plan your application

When is volume-based feeding a good starting point?

Review it when material flows consistently and your process can tolerate changes in delivered mass as bulk density varies.

What information should I send?

Send your material name, bulk density, particle size, moisture, and minimum, normal and maximum rate. For batch work, include the batch range, cycle time and time between batches.

How do you evaluate feeding accuracy?

Tell us how accuracy will be measured, the collection period or batch size, and the operating conditions. A trial with actual material can help establish the result.
