The MVB 1510/15 at Audimat

The MVB 1510/15 is a size 50 vertical vibrator, with the mounting flange at the top and a shaft projecting on both sides. At 1’500 rpm it is rated for a maximum centrifugal force of 14,7 kN, that is 1500 kgf.

Its spheroidal graphite cast iron frame gives it both strength and resilience, which matters on a circular screen under continuous loading. Audimat, official Italvibras distributor.

Applications of the MVB 1510/15

Particularly suited to the following applications :

Design and operation

The MVB 1510/15 houses a three-phase asynchronous motor with 4 poles, supplied from 220 to 690 V at 50 or 60 Hz. Its frame is spheroidal graphite cast iron, chosen for its strength and resilience, and its bearing flange transmits the load evenly. The bearings use a specific geometry, designed to take both heavy radial and axial loads. Protection IP66, impact resistance IK08, continuous duty S1 from −20 °C to +40 °C.

Mounting is typically vertical, but any position remains possible. The shaft projects on both sides, allowing a group of weights to be fitted at each end. The lifting rings are integral with the frame : there are no eyebolts on the shaft, and the machine must be handled by these lifting rings. Inverter control is available from 20 Hz up to base frequency, at constant torque.

The only certified size in the series
In the MVB series, only size 50 carries ATEX certification. The catalogue’s certification block names « MVB gr. 50 » and « MVB-FLC gr. 50 » explicitly, and only this size is assigned a surface temperature — 150 °C. Certification II 2 D, Ex tD A21 T150 °C IP66, zones 21 and 22, standards EN/IEC 60079-0 and 60079-31. To these are added CSA approval (certificate LR 100948) and KOSHA certification (11-AVG BO-0359).
