Non-Food Solution

Powder Weighing Solution

Dosing fine chemical powder requires precision that ordinary filling methods can't hold. Our loss-in-weight feeders are tailored to manage carbon black, pigments, and other clump-prone industrial powders — for powders prone to bridging, caking, or dusting, we pair the right screw and hopper design to keep continuous feeding stable and cut down on powder escape.

Equipped with precision twin-screw or single-screw metering, our feeders minimize spillage and maximize dosing accuracy for low-density, dust-prone powders in continuous feed operation.

FAQS

What's the difference between a loss-in-weight feeder and a simple volumetric screw feeder for powder dosing?

A loss-in-weight feeder continuously weighs what's leaving the hopper and adjusts screw speed in real time to hold the target feed rate. A volumetric feeder just runs the screw at a fixed speed and assumes the material's bulk density stays constant — which real chemical powders rarely do.

Why do you recommend twin-screw over single-screw for something like carbon black or pigment?

Twin-screw configurations use two screws working together to actively break up bridging and caking in the hopper, which matters for cohesive, low-density powders like carbon black. Single-screw units suit more free-flowing chemical powders where bridging is less of a risk.

What dosing accuracy can I expect from a gravimetric feeder on chemical powder?

Our loss-in-weight feeders hold roughly ±0.5% adjusted feeding accuracy, though actual performance depends on your powder's flow characteristics and target feed rate.

Our process runs continuously rather than in discrete batches — does that change how accuracy is controlled?

Yes. Continuous chemical dosing doesn't have the batch-by-batch fill-station checkpoint that food packaging lines rely on, so the feeder has to hold accuracy on an ongoing basis rather than getting corrected after each fill — that's the core reason gravimetric control matters more here than in batch filling.

What feed rate range do your loss-in-weight feeders cover?

The line spans roughly 100 g/h on the micro-flow models up to 1,000 kg/h on the large-flow models, so sizing depends on your actual throughput requirement.

Can these feeders integrate with our existing PLC or SCADA system?

Yes. Our feeders run on a 7-inch touchscreen with Modbus protocol support, which our team can configure to talk to most plant-level control systems.
