Our scope of work with screw conveyors is largely limited to drives i.e. gearbox and sealings improvements for the bottom bearings. Over the years we have seen what others have offered, including complex custom made seals that cost a small fortune to simple and effective solutions that simply means replacing brand X with brand Y.
That said I am also mindful to recommend a single product for every application. The product being conveyed, shaft size and shaft speed, as well as overall focus on energy consumption are all factors that we take into consideration when recommendation one of our our 5 solutions.
If you have a screw conveyor and are fed up with worn shafts, leaking product, damage to drives and couplings, please contact Lager for an independent assessment.
