Agitator boosts efficiencies in minerals processing
4th Quarter 2016Electrical switching & drive systems & components
The X-series Agitator with integrated extended bearing distance (EBD) from SEW-Eurodrive represents the latest iteration of the well-known X-series, designed specifically for mixing applications such as minerals processing.
This consists of a standard gearbox with a modified output side in order to increase the radial and axial forces. The distance between the low-speed shaft bearings has been increased, while bearings with larger dynamic capacities have been used.
“An integration of the EBD with axial and/or radial bearings into the gearbox is far more cost-efficient for the customer than a purely external bearing configuration mounted on the application,” says head of department – engineering, Andreas Meid. The main applications for the X-series Agitator are mixers, agitators and aerators, where high radial forces, combined with axial forces, act on the low-speed shaft.
“We have looked at all competitive products available on the market, and incorporated the strongest features into our unit. So we have extra features in addition to unique accessories on offer, such as a condition monitoring system,” Meid explains.
The main advantage of the X-series Agitator is that it is essentially an off-the-shelf unit that uses existing components. The entire design is fully integrated, which makes for a highly efficient and compact unit that is easily maintainable. Different lubrication options are available, such as bath lubricated with expansion tank, or pressure lubrication with drywell. All the lubrication piping is integrated fully into the unit, which is thermally optimised as well. Different filter options are also available.
