The VB 15/2510-D-E at Audimat

The VB 15/2510-D-E is the increased safety version of the VB. The same mechanical performance — 24,5 kN for 68,0 kg — but with certification covering gas atmospheres as well as dust.

It is the only way to equip a circular sieve in zone 1 or 2 in this format. Audimat, official Italvibras distributor.

Applications of the VB 15/2510-D-E

Design and operation

The VB 15/2510-D-E houses a three-phase asynchronous motor with 4 poles, supplied from 220 to 690 V. Frame and end shields in spheroidal graphite cast iron, alloy steel shaft with isothermal hardening, bearings of specific geometry taking radial and axial loads. Protection IP66, impact resistance IK08, insulation class F, tropicalised as standard, continuous duty S1 from −20 to +40 °C.

Increased safety : gas AND dust
Certification II 2 G and II 2 D under directive 2014/34/EU and the IECEx scheme : Ex e IIC T3 or T4 Gb on the gas side, Ex tb IIIC T150 °C Db on the dust side, standards EN/IEC 60079-0, 60079-7 and 60079-31. Zones 1, 2, 21 and 22. To these are added KOSHA certification (11-AVG BO-0346 to 0351) and EAC certification. Protection method « e » does not contain the explosion : it prevents a source of ignition from arising. Hence the tE time in the table above, which sets the time within which overload protection must trip.

PWM inverter control is available from 20 Hz up to base frequency, at constant torque, only where a correctly connected PTC thermistor is fitted. The catalogue also states that the components involved in the protection are checked and recorded at 100 %.
