RUBERG vertical dosing feeders produce an equal bulk stream in a product gentle manner. They are adequate for the discharging of free-flowing dry materials from bins, silos, mixing apparatus etc. Because of the polygon effect at the rotation of the spherical designed impeller bridging with poor-flow products on the one hand and flush-like discharging with particular easily flowing products on the other hand is prevented.
So e.g. subsequent apparatus like sifting machines, continuous conveyors, packaging plants etc. can be fed.
In a solid housing there is an impeller with 6 up to 12 open chambers. It is axially and radially led in maintenance-free bearings and seals. The drive and the adjustment of the throughput rate take place via a directly flanged gear motor with variable speeds.
Designed in high-quality stainless steel materials. With hygienic surfaces and seals they will be applicable in the chemistry, food and pharmacy area. The nominal sizes and connection flanges conform to well-established standard lines. So RUBERG vertical dosing feeders can be integrated into consisting pipelines and plants. Equipped with a blowing collar and position generator for the impeller RUBERG vertical dosing feeders also can be used as dust-proof and pressure tight closing shutoff device. Variable clearances for sensitive granules, heating jacket for tempered products, integrated cleaning and CIP nozzles are examples for large accessories.
