The materials handled within the recycling industry are vast and varied; from paper and plastics to glass and wood, metals and textiles to building materials and more – and the ways in which these materials require handling through processes arguably even more so. The advantage of vibration technology is that it too is vast and varied, and the many methods of vibration handling can be used in equipment designs that solve a range of recycling applications.
In most cases, materials need to be separated out into what is usable for recycling and what is waste. A linear vibratory screen provides efficient separation by size whilst feeding onto the next process. This is often used to separate dust from usable materials, or to remove oversize pieces from bulk product – policing the material so that the usable product is separated from anything that requires further processing. In cases of bottles, particularly glass or plastic, liquid residue can often cause a problem that can be solved with a dewatering screen. By feeding the glass or plastic over a screen, vibrating equipment can separate the liquid from the material – the material feeding onto the next process or into a container, and the liquid draining out to a separate specified area. This solution is efficient and effective, and care has been taken with vibrating screen designs to ensure that clean down is easy.
When materials such as recycled plastics, glass or metal are filled into bulk bags or IBC containers, filling the containers to maximum capacity can prove tricky. The irregular parts often fill on top of one another, rather than spreading out to the corners of the container, and can also start to ‘cone’ into a peak at the top. In order to ensure filling capacity and bag stability, a vibrating table can be implemented to compact the material – encouraging movement into the corners of the container and levelling out the peaking material at the top of the bag. Low level vibratory tables sit close to the floor, and as container filling issues are usually detected prior to hopper installations, can be designed to suit pre-existing filling set ups.
Efficient movement of materials and transporting those materials between two locations is one of the most common requirements in the recycling industry. A vibratory conveyor, driven by twin vibrator motor drives, is well suited to such applications, providing efficient high volume conveying with low power consumption. Unlike belt conveyors, the trough or tubular structure of a vibrating conveyor does not require routine maintenance as the conveying trough does not easily wear down and there are no points in which material could get trapped. This also makes for easy clean down, reducing the amount of inefficient time within a time-conscious industry.
A vibratory feeder offer the same time-saving qualities such as easy clean down and low wear, but uses an electromagnetic drive that allows for control over the flow of material. This is particularly advantageous within the recycling industry when needing to regulate flow or fill a container to a certain weight. The instantaneous stop/start control allows for accuracy in precision filling applications, and the ability to slow down or speed up product flow allows for versatility in feeding a variety of materials, as often is the case with recycling processes. The control that a vibrating feeder offers is also often used to spread material over wide video inspection or picking belts – spreading the product out into a manageable stream in order to allow for effective video inspection or for an operative on the picking belt line.
Efficient material handling begins with consistent feeding. In many production environments—from aggregates to composting—irregular loading can lead to spillage, downtime and uneven material flow downstream. Feeding conveyors play a critical role in solving this challenge by acting as a buffer between incoming loads and the machines that rely on steady throughput.
This blog explores how feeding conveyors function, where they’re best applied and what features make them effective.
A feeding conveyor, sometimes referred to as a surge conveyor or feeder loader, is designed to manage the flow of bulk materials by controlling the rate at which they’re transferred to the next stage of processing. Unlike standard conveyors that assume a consistent infeed, feeder conveyors are built to handle surges—like those from an excavator or loader—without causing overflow or clogging.
At the core is a variable-speed feeder belt beneath a hopper. This setup helps absorb inconsistent loads and release material smoothly onto a main conveyor, screen or crusher. The result is reduced spillage and more consistent feed rates across the system.

Feeding conveyors offer benefits across a range of material-handling challenges:
These conveyors are especially useful in scenarios where materials are sticky, bulky or delivered in uneven amounts.
The effectiveness of a feeding conveyor depends on several configurable features:
These components help adapt the feeder to different material types and handling conditions, making it a flexible tool across various industries.
Feeding conveyors are especially beneficial when:
They’re commonly seen in applications involving aggregate processing, recycling, organics and material blending operations.
Anaconda offers a range of feeding conveyors designed to meet varied production needs:
All FTR models use a standard 4.27 m (14-foot) belt feeder and support a wide range of bolt-on options, including tipping grids, vibrating decks, overband magnets and augers. These allow operators to tailor the unit for use in either aggregate or organic applications. The FTRs are also designed with a shared set of components across models, simplifying maintenance and spare parts inventory.
