Overview

Controllable feeding for conveying, dosing & screening

Electromagnetic vibratory feeders convey, dose and screen bulk materials and powders with exceptional control. Because the drive is electromagnetic — not a rotating motor — feed rate is set electrically and responds instantly, making the feeder ideal for accurate metering into process and packaging lines. Linear feeders suit everything from heavy minerals to delicate snack foods.

FAQs

Electromagnetic Vibrating Feeder — common questions

How is an electromagnetic feeder different from a motorised one?

An electromagnetic feeder is driven by an electromagnet rather than a rotating motor, so it has no gearboxes or bearings to wear, starts and stops instantly, and its feed rate can be varied precisely with a simple controller — ideal for accurate dosing.

Can the feed rate be controlled automatically?

Yes. Feed rate is set electrically and can be linked to a variable controller or your plant control system for automatic, repeatable dosing and metering.

Is a food-grade / stainless version available?

Yes — stainless trays and hygienic designs are available for food, pharma and chemical duties, including light-duty units for packaging lines.

How do you size the feeder?

Share your material, required feed rate (kg/h or t/h), particle size and the machine it feeds, and our engineers will recommend the right tray size and drive.
