The Stockpile · Pile 02 — The Parts
Ten families of vibrators — sized to the wall, placed where they work.
Ten families of vibrators from Cougar, Italvibras, Oli and more: screen vibrators, truck vibrators, electric, hydraulic, piston, roller, turbine, ball, portable pneumatic and railcar vibrators. When your material needs to flow — and keep flowing — the right vibrator in the right place does quiet, reliable work for years.
Channel-and-stiffener mounting spreads the force and saves the vessel wall. If a vibrator cracked your hopper once, the mount — not the vibrator — was usually the culprit.
| Type | Character | Best for |
|---|---|---|
| Rotary electric | Continuous, tunable force, quiet-ish | Screens, feeders, dense long-duty flow help on bins |
| Pneumatic ball / roller | Simple, cheap, runs anywhere with air | Hoppers and chutes needing regular shaking |
| Pneumatic piston | Directional thump, single or repeated | Knocking wall cling loose; railcar and hopper duty |
| Turbine | High frequency, lower noise | Noise-sensitive plants, finer materials |
| Symptom | Likely cause | Fix |
|---|---|---|
| Vibrator runs, material sits | Fine cohesive powder compacting — the classic trap | Stop vibrating; this is cannon territory (see the comparison) |
| Cracked welds at the mount | Mount plate too light, or channel missing | Reinforced mount to manufacturer spec — not just a thicker weld |
| Pneumatic unit slowing down | Wet or dirty air supply | Filter-lubricator upstream; drain the drops |
| Electric unit tripping | Force setting too high for the structure, or bearing end-of-life | Check eccentric settings and current draw |
| Noise complaints | Ball type on thin steel = bell | Turbine or piston swap; isolate the mount |
Pneumatic units are simple, robust and safe for wet or dusty spots with plant air handy; electric units shine on screens, feeders and continuous duty. Application picks the family — send us the vessel and material.
Correctly sized and mounted, no. Damage comes from oversizing and bad mounts. Sizing help is free — use it.
Vibrators keep free-flowing material moving; cannons break cohesive buildup and bridges, especially high on the vessel or in hot service. Many plants run both.
