The Invicta BL80-315/6 is the highest force 6 pole electrical vibrator currently on the market, producing an output of 31500 kgf at 960 rpm. To achieve this output the bearings, bearing housings and rotor shaft have all been up-rated. In-house testing indicates the higher output model will retain the reliability of the other models in the BL80 range.
This addition to the established range has been specifically designed to power the largest sizes of screens and feeders and provides OEMs with a viable alternative to externally-driven exciters. Electrical vibrators are often preferred over exciters due to their simplicity of design (fewer moving parts), compact footprint and overall flexibility.
The BL80-315/6 retains the same features and footprint of the existing BL80 range. Using the same purpose-built 12.5kW winding throughout the BL80 range allows the use of existing control gear, thus providing a simple route to upgrading existing units and retrofit options. It will shortly be available as the ATEX approved BLz version for use in Zone 21 & 22 applications.
The BL80-315/6 stands as the largest electrical vibrator in the current Invicta range.
