Integrated Pre-Screening (Scalping)
The heavy-duty grizzly section removes undersized material and soil before it enters the crusher, effectively increasing the crusher’s effective capacity by 20-40%.
FRP Grizzly Feeder is a heavy-duty vibrating feeder designed to combine continuous material feeding with efficient primary scalping. It is widely used in the front end of crushing circuits to provide a stable and controlled feed to primary crushers.
With a high-amplitude linear vibrating motion, the feeder regulates the material flow while simultaneously removing undersize materials, fines, and clay through the grizzly bars before the crushing stage. This integrated scalping function helps reduce unnecessary load on the crusher, minimize the risk of chamber blockage and crusher overload, and improve the overall efficiency and throughput of the primary crushing circuit.
The defining value of an FRP Grizzly Feeder lies in its ability to optimize the entire primary crushing circuit. In high-capacity mining operations, feeding raw material directly into a jaw crusher without scalping leads to "inefficient crushing," where the machine wastes energy on fines that are already at target size. Our Grizzly Feeders solve this by utilizing a high-G force vibration profile that stratifies the material bed, forcing fines to the bottom and through the bars. This ensures the primary crusher only processes the oversized rock it was designed for, leading to lower energy consumption per ton and a more stable production rhythm.
