Weighing & Dosing

Weighing Hopper

CYprocess weighing and dosing systems — also called weigh hoppers or batching scales — proportion multiple powders to a target weight under gain-in-weight or loss-in-weight control. High, medium, low and pulse feed stages approach each setpoint with controlled accuracy.

Weighing Hopper

Overview

About Weighing Hopper

How this equipment works in powder handling lines and what to consider when selecting it.

Working principle

The hopper is suspended on load cells and filled in stages, so most of the weight arrives quickly and the final increment is added slowly. That fast-then-slow sequence is what produces the accuracy: the feeder rate is reduced as the setpoint approaches rather than stopping the flow abruptly.

Options and integration

Recipes for ten or more ingredients are stored and recalled from the PLC, with screw, belt or vibratory feeders running under VFD control. Closed conveying with automatic dust recovery keeps the batching area clean, and the discharge feeds mixers, reactors or packing lines.

FAQ

Weighing Hopper FAQ

Common questions about selection, integration and quotation.

Gain-in-weight adds material to a vessel on load cells and suits batch recipes. Loss-in-weight measures what leaves a hopper over time and suits continuous feeding. Many lines use both: gain-in-weight for batching, loss-in-weight for the final additive.
