One of the biggest challenges in mining and quarrying is the blockage caused in vibrating feeders and grizzly screens by wet and sticky material. This issue can be resolved with a wobbler feeder. Self-cleaning disc-shaped elliptical shafts rotate in synchronization, removing fine materials, mud, and waste that should not enter the main crusher through the designed gap. Wobbler Feeders are typically used in applications with an apron feeder positioned in front.
