The Invicta stand B31 at Hillhead 2012 will principally feature the new range of BLz 78 and BL 80 rotary electric vibrators (Fig.). These robust units with an 8-bolt fixing arrangement are amongst the most powerful vibrator motors currently available anywhere and can supply centrifugal forces of up to 23 000 kgf from a 12.5 kW winding. The whole BLz range of vibrators is ATEX-approved for use in Zone 21 and 22 areas. In addition a broad selection of electrically-powered models for use on vibratory feeders, conveyors, screens and discharge devices will be on display along with hydraulically-driven rotary vibrators designed for use on mobile equipment and in locations where no power supply is available. Part of the stand will be devoted to pneumatic piston vibrators, designed for low output applications, and a display of Invicta control panels suitable for single or multiple vibrator installations incorporating control logic, current monitoring, running interlocks and various designs of braking system.
