22.10.2018 Forced feeding system for bucket elevators

Simatek Bulk Systems, Hoeng, Denmark, points out that a pendulum bucket elevator is a popular choice for gentle and flexible conveying of bulk products, but when it comes to fine powders and very abrasive products this can be a challenge. The company has introduced a Forced Feeding System which – in combination with other initiatives – makes pendulum bucket elevators well suited for conveying complex powders that have poor flow properties, as well as being fragile, abrasive or explosive. At next month’s SOLIDS Dortmund it will be exhibited on Stand R59 in Hall 6.

By adding a screw feeder module to the patented Simatek Drum Feeder it is possible to secure a high filling degree of the elevator buckets. This feeding system is based on individual batch feeding of the elevator buckets without product spillage. In combination with the Simatek Drum Feeder it is possible to convey with elevator buckets without overlap. This is to eliminate mechanical contact between the buckets, friction and the use of guides. Conveying with the FRB (free rotating buckets) system will ensure much more operational reliability as well as minimum wear.

In traditional pendulum bucket elevators the buckets are suspended between parallel roller chains. However, certain powder types will generate significant wear and therefore roller chains are generally not the best solution for abrasive and fine powder types.

However, when it comes to very abrasive products or applications for which chain lubrication is not an option, the company offers bearing suspended buckets. With these buckets the wear on the roller chain is basically eliminated. The closed and lubrication-free bearing construction generates less friction and has a documented 40% power consumption reduction.
