Polygonmachine PWF Series Wobbler Feeders
Polygonmachine PWF Series Wobbler Feeders
Polygonmachine PWF Series Wobbler Feeders are designed to handle wet, sticky, and clay-contaminated materials that conventional vibrating feeders struggle to process.
They ensure smooth, clog-free material flow while effectively separating fines from oversize feed before it enters the primary crusher.
Engineered for high-capacity, continuous operation, these feeders are ideal for heavy-duty mining, quarrying, and aggregate applications.

Key Features
Self-Cleaning Roller Design:
Unique elliptical rollers continuously rotate against each other, preventing clogging and enabling self-cleaning during operation.
Efficient Fines Separation:
Fine materials fall through adjustable gaps between rollers, reducing crusher wear and increasing plant efficiency.
Heavy-Duty Frame Structure:
Constructed from high-tensile steel with reinforced cross beams for maximum durability under heavy loads.
Adjustable Gap System:
Hydraulic or mechanical adjustment allows quick control of separation size from 40 mm up to 150 mm.
Smooth Material Flow:
Continuous rotation ensures consistent feed, even with wet or sticky materials like clay, limestone, and marl.
Low Maintenance Requirements:
Sealed bearings, centralized lubrication, and easily replaceable wear components ensure long service life and reduced downtime.
Variable Speed Drive:
Equipped with frequency inverter (VFD) for adjusting shaft speed according to feed type and desired output.
High Capacity & Energy Efficiency:
Delivers superior throughput while consuming less power than conventional vibrating or apron feeders.
