GOOD VIBRATION
Supplied and delivered by Audimat, official Italvibras distributor : 2-pole vertical vibrator with a top mounting flange, for circular screens and sieves.
ATEX CERTIFIED — DUST — ZONES 21 & 22
AUDIMATAvailability
The MTF 3/800-S02 is a size 30 vertical vibrator, with the mounting flange at the top and the weight covers at the opposite end. At 3’000 rpm it delivers 7,34 kN on 50 Hz for 17,0 kg.
This geometry lets it mount at the centre of a circular screen, where a foot mounting would have no bearing surface. Audimat, official Italvibras distributor.

Particularly suited to the following applications :
The MTF 3/800-S02 houses a three-phase asynchronous motor with 2 poles. The frame is high-strength aluminium alloy, the bearing flange cast iron or aluminium with a steel bearing seat, its geometry transmitting the load evenly. The shaft is alloy steel with isothermal hardening and the bearings use a geometry specific to Italvibras. Protection IP66, impact resistance IK08, continuous duty S1.
Force is set with laminated or clamped eccentric weights : the lower group can be phase-shifted relative to the upper one, and a graduated scale reads force directly as a percentage of maximum. That is what makes adjusting the screen’s behaviour straightforward, with no calculation and no dismantling.
Two mounting points worth knowing. The terminal box is deliberately kept compact to let tools through that fixes the vibrator to the machine. And IP66 sealing is only achieved once the vibrator is mounted : it is provided by a special gasket to be fitted into its seat on the coupling flange.
