FORGED STEEL SUSPENSION SYSTEM
Each Vibra Screw Bin Discharger is supported by a series of forged steel hangers, fitted with steel core elastomer vibration isolators. The result is enormous strength along with near total isolation of the Bin Discharger vibration from the bin and surrounding structure.

The forged hangers carry 70,000 [small] and 120,000 [large] lbs load each. This is ultimate capacity [of the steel forging], so BA does not fall off bin. Useable [operating] capacity is determined by the isolators which is approx. 5000 lbs per hanger. So for high headloads we look at the isolator capacity and either add more forged hangers or cable hangers to keep the isolator loading within limits.

PATENTED BEADED SLEEVE
Molded in one piece with 4 retaining beads, this Vibra Screw innovation has eliminated the problem of sleeve leakage and slippage. Stainless Steel clamps fit securely between the beads and tighten easily and effectively. This sleeve design is so effective it will withstand 10 PSI internal pressure and is standard in all our Bin Discharger designs. Special compounds for high temperature and a flanged bolted sleeve for high pressure are also available.

OIL-LUBRICATED GYRATOR OR GREASE LUBRICATED VIBRATOR
Two vibrators to choose from.

Oil Lubricated and cooled Gyrator offered exclusively by Vibra Screw guaranteed for 50,000 hrs of use. The large force-generated eccentric weights are mounted on a massive shaft revolving in oversized, precision bearings. The drive motor is mounted inline with the eccentric weight assembly, but works through a floating coupling so that the motor bearings carry only the motor rotor. Motor life is several times that of typical shafted motor.

Grease lubricated gyrator A special designed rotating motor with oversized shaft, bearings and eccentric weights on the shaft generates centrifugal force. Force output is adjusted by changing the unbalance of the weights.
