RUD Gambarotta heavy duty apron feeders provide controlled, reliable extraction of heavy and abrasive bulk materials in demanding environments. Built for Australian mining, quarrying, cement and steel industries, they offer high durability, reduced maintenance and strong performance in harsh, remote and high-throughput conditions.

RUD Gambarotta EP and EPP series heavy duty apron feeders are designed for reliable extraction and controlled feeding of large, heavy and abrasive bulk materials. With reinforced steel pans, heavy duty chains, impact rails and high strength drive components, they deliver consistent throughput while protecting downstream equipment. These feeders are widely used across the Australian mining, cement, quarrying and steel industries, where durability, load control and low maintenance are essential.

The Role of Apron Feeders in Material Handling

The first stage of material handling, extracting material from a hopper, stockpile or unloading system, is one of the most challenging. Equipment must manage high impact loads, large lump sizes and abrasive materials without failure. Apron feeders are designed for this task. Unlike conventional conveyors, they provide a slow, controlled and positive feed, making them suitable for heavy duty, continuous operations. In Australia, where sites often operate remotely and around the clock, reliability at this stage is critical to maintaining plant uptime and avoiding costly disruptions.

How Apron Feeders Work

EP and EPP feeders use overlapping steel pans mounted on dual parallel chains to form a continuous moving deck. This deck travels slowly beneath the hopper, extracting and conveying material at a controlled rate. This movement prevents surging and ensures that downstream equipment (crushers and screens) receives a steady feed. Impact rails beneath the loading zone absorb the energy of falling material. The pans flex elastically under load, transferring most of the impact force into the frame before returning to their supported position on rollers, reducing stress on moving components. Support rollers with double ball bearings eliminate sliding contact, improving efficiency and reducing wear, which is important for sites with limited maintenance access.

Choosing the Right Feeder: EP vs EPP?

EP Series - Proven Performance

The EP series is designed for reliable performance in standard heavy duty applications.

• Overlapping steel pans for material retention
• Dual chain system for stable tracking and load distribution
• Adjustable speed via frequency control
• Suitable for a wide range of bulk materials
• Balanced durability and cost efficiency

EPP Series - Reinforced for Extreme Conditions

The EPP series includes additional reinforcement for more demanding environments.

• Strengthened frame for higher static and dynamic loads
• Heavier pans for large lump sizes and high impact
• Hardened chain components for extended wear life
• Designed for continuous, high capacity operation

EPP feeders are suited for extreme loads, high drop heights and highly abrasive materials, common in Australian mining and quarrying.

Key Features That Drive Performance

• Impact Absorption System - Impact rails protect roller bearings by directing loading forces into the frame
• Heavy Duty Pans - Thick steel pans withstand continuous impact and abrasion, with an armoured anti-spillage lip
• Chain and Drive Design - High alloy steel chains with induction-hardened wear surfaces extend service life; replaceable toothed segments simplify maintenance
• Wear Protection - Reinforced side guards with replaceable liners guide material and resist abrasion
• Capacity Control - Variable speed drives and material bed depth ensure stable downstream processing
• Flexible Installation - Feeders can be dismantled for retrofit and configured with hoppers or extended designs

How are the RUD Gambarotta Apron Feeders suited for Australia?

Australian operations present unique challenges that influence equipment selection.

• Remote and Harsh Environments - Sites such as the Pilbara and central Queensland operate in high temperatures, dust and abrasive conditions, requiring robust equipment with long service intervals
• High Throughput Requirements - Large scale operations require consistent and high capacity material flow
• Handling Large Lump Sizes - Common material often includes large and irregular lumps, which apron feeders handle without blockage or excessive wear
• Integration and Safety - Used in fixed and semi-mobile plants, controlled feed reduces surging and improves safety
