An apron weigh feeder is a heavy-duty feeding and weighing system designed to continuously measure and control the flow of bulk, heavy, abrasive, or coarse materials.

How does an apron weigh feeder work?

An apron weigh feeder combines the functions of an apron feeder and a continuous weighing system:

Material loading – Bulk material is discharged from a hopper or silo onto the apron conveyor.

Apron conveying – Heavy-duty steel pans/plates carry the material forward.

Continuous weighing – Load cells and a weighing system measure the material flow.

Speed control – The drive speed is automatically adjusted to achieve the required feeding rate.

Flow monitoring – The control system displays instantaneous flow rate and accumulated material quantity.

What materials can it handle?

Apron weigh feeders are particularly suitable for difficult materials such as:

Limestone

Coal

Clinker

Iron ore

Slag

Gypsum

Rock

Mineral ores

Cement raw materials

Other heavy and abrasive bulk material

Apron Feeder vs. Apron Weigh Feeder

The main difference is weighing capability.

Apron Feeder: primarily transports and feeds bulk materials.

Apron Weigh Feeder: transports and feeds materials while continuously measuring the material flow rate and total quantity.

Therefore, an apron weigh feeder is especially useful when a plant needs both reliable heavy-duty feeding and accurate material measurement.

Typical applications include cement plants, mining, metallurgy, power plants, aggregate processing, and mineral processing.
