Undersize & Oversize Belt Conveyor
Description
Undersize Pellet Collecting Belt Conveyor
​
The purpose of the Undersize Belt Conveyor is to collect fines and undersize pellets that fall through the roller screen/feeder's gaps that failed to meet the sizing criteria. The roller's gap is normally 9 mm; any green pellets smaller than the gap fall through the gaps onto the Undersize Belt Conveyor underneath the roller screen/feeder and are recycled back to the green pelletizing area.
​
The roller screen/feeder, which is located above the Undersize Belt Conveyor, can be a single, double, or even triple deck design. The Undersize Belt Conveyor is generally located underneath the lower deck if the roller screen/feeder is a double deck design. Once the fines and undersize pellets are collected, they are then conveyed back to the green pelletizing area.

Oversize Pellet Collecting Belt Conveyor
The Oversize Pellet Collecting Belt Conveyor is designed to handle green pellets that exceed the specified size range and therefore do not pass through the gaps of the roller screen or roller feeder. In typical pelletizing applications, the roller gap is set at approximately 16 mm. Green pellets larger than this opening are separated during the screening process and directed onto the oversize belt conveyor for further handling.
​
The oversize belt conveyor is strategically positioned to receive rejected oversized pellets directly from the roller screen/feeder discharge. Once collected, these pellets are conveyed in a controlled and continuous manner back to the green pelletizing area, where they can be reprocessed and reintroduced into the pellet formation cycle. This recirculation helps maintain a consistent pellet size distribution and supports stable operation of the downstream screening and induration processes.
​
Designed for continuous-duty operation, the Oversize Pellet Collecting Belt Conveyor features a robust mechanical structure and smooth material handling characteristics suitable for fragile green pellets. Belt speed, conveyor layout, and transfer points are carefully engineered to minimize pellet impact and degradation during transport. The conveyor can be integrated seamlessly with single-, double-, or multi-deck roller screen configurations and adapted to various pellet plant layouts.
​
By efficiently returning oversized pellets to the balling circuit, the Oversize Belt Conveyor plays an important role in material recycling, process efficiency, and overall pelletizing line stability.
