Polygonmachine Vibrating, Grizzly and Prescreening Feeders
Polygonmachine Vibrating, Grizzly and Prescreening Feeders
Polygonmachine Feeders are engineered to ensure efficient, continuous, and controlled material flow in crushing and screening plants.
Designed to handle a wide range of materials—from fine aggregates to large, abrasive rocks—they deliver steady feed rates that optimize crusher performance and plant productivity.
The series includes Vibrating Feeders (PVF), Grizzly Feeders (PGF), Belt Feeders (PBF), Apron Feeders (PAF), and Wobbler Feeders (PWF), each tailored for specific material types and operational demands.
PVF Series – Vibrating Feeders
Application: Universal feeder for crushing stations, providing steady and metered flow to crushers or screens.
Best for: Dry to slightly damp, non-cohesive aggregates and ores.
Advantages: Adjustable stroke and frequency (VFD), tunable inclination, low power consumption, and replaceable liners.

| PBF 1225 | 550 | 1200×2500 | 150 | 0.35 | 7 |
PAF Series – Apron Feeders
Application: Heavy-duty feeding for mining, quarrying, and recycling with large lumps and high impact.
Advantages: Forged pans, deep-profile flights, high-torque drives, sealed skirting, and long service life.
| Model | Capacity (tph) | Width (mm) | Max Feed (mm) | Chain Speed (m/s) |
| PAF 65XX | 120–360 | 650 | 325 | 0.1–0.3 |
