Apron FeedersGlobal Supplier & Manufacturer of Mineral Processing Solutions
When feed material is heavy, abrasive, or includes large run-of-mine rock with unpredictable surge loads, a conventional belt or vibrating feeder isn’t built for the duty. The Apron Feeder is engineered for exactly this environment — absorbing impact loads at the feed point, handling highly viscous and sticky materials, and delivering a consistent, controlled feed rate to the primary crusher or downstream equipment.
Product Features
- Heavy-duty overlapping pan design absorbs large material impacts at the feed point and eliminates spillage throughout the conveying length.
- Sealed-for-life chain and rollers: no routine lubrication required, reduced maintenance cost over equipment life
- Abrasion-resistant pan material specified for your ore type and operating conditions
- Customizable lengths to match circuit layout and surge pocket requirements
- Variable-frequency drive provides stepless control over feed rate — consistent delivery to the crusher under varying load conditions

Frequently Asked Questions
What materials is the Apron Feeder designed to handle?
The Apron Feeder is built for heavy-duty applications involving large, abrasive, and high-impact feed material — run-of-mine ore, quarry blasted rock, and sticky or clay-bearing material that would damage or choke lighter feeders. If your primary feed point takes large surges or highly variable loads, the Apron Feeder is the correct starting point for the circuit.
How is the feed rate controlled?
Feed rate is controlled via a variable-frequency drive (VFD) motor, which allows the operator to adjust belt speed continuously to match downstream crusher demand. This prevents both flooding and starvation at the crusher — two conditions that accelerate wear and reduce throughput predictability.
What maintenance does the Apron Feeder require?
Utilizing modern sealed-for-life chain and carrier rollers eliminates routine lubrication requirements—saving hours of ongoing maintenance labor. Inspection of the pans for wear and monitoring of drive components make up the typical maintenance schedule. We can assist in developing an inspection interval appropriate to your material and operating hours.
Can the feeder length be customized to fit our plant layout?
Yes. Center-to-center lengths are available from 3 to 20 meters, and configurations outside this range can be accommodated on application. We review the circuit layout and surge pocket requirements during the engineering phase to confirm the right configuration before manufacturing begins.
Is the Apron Feeder suitable for sticky or wet materials?
If your circuit has sticky and moderately wet materials, our Apron Feeders can handle those types of materials. For feed material that is heavily clay-laden, high-moisture, or prone to clogging conventional feeders, we would also evaluate the Wobbler Feeder as an alternative or complementary solution. The right choice depends on the specific material characteristics — we can help you work through the decision.
Who do I contact to discuss whether the Apron Feeder is right for my application?
Contact your regional AMPCO Minerals sales representative or reach out through our website. We will ask about your material, feed size, throughput requirements, and site conditions — and give you a direct assessment of whether this feeder fits your circuit.
