Product Introduction：The GZG self-synchronous inertial vibrating feeder uses two vibration motors to excite itself in sync. It’s a continuous quantitative feeding device, mainly used in concentrators under raw ore silos with jaw crushers, replacing lightweight plate feeders with better cost efficiency. The GZGF version is dustproof and sealed.
1. How It Works
The two motors spin in opposite directions but in sync. Their eccentric blocks create overlapping directional forces, making the tank body move back and forth linearly. Ore in the trough gets periodically lifted and moves forward in a parabolic path, letting it feed evenly and continuously. You can adjust the feed by changing the eccentric block or using a frequency converter. Plus, an electronic brake control helps the machine cross the resonance zone quickly when shutting down, reducing leftover vibrations.
2. Main Parts
Feeding trough (wear-resistant liner), two vibration motors, shock-absorbing spring assembly, hanging seat/support, electrical control cabinet. It comes in two installations: split-seat and suspended, with either open (GZG) or sealed (GZGF) troughs.
3. Suitable Materials (Gold Ore)
Good for bulk or granular stuff like gold ore and quartz veins; standard feed size ≤ 200mm; works with medium moisture content and small amounts of mud.
4. Features
Lightweight with a small footprint; the whole machine weighs much less than plate feeders, meaning lower investment.
Starts quickly, responds fast, easy to adjust, and integrates with central control.
Ore moves forward in jumps, so bottom wear is low; low power use and simple maintenance, with just the vibrating motor needing attention.
Can add a slotted screen plate to pre-screen and separate fine mud while feeding.
5. Comparison with Gold Mine Support Equipment (Key for EPC)
- GBQ Light/Heavy Plate Feeder: Handles large silo pressure, lots of big ore pieces, strong impact when discharging; best for plate feeding and crushing resistance.
- GZG Vibratory Feeder: Good if silo columns aren’t tall, ore blocks are medium size; cost-effective and lightweight.
- DK Disc Feeder: Only for fine ore bins or ball mills for fine material; not for big raw ore pieces.
6. Model Example
GZG80-4 means groove width 800mm, length 4m; F at the end (GZGF) shows it’s sealed and dustproof.
