The Rotary Sweep Unloader are designed for unloading flat bottom silos containing products with various densities, such as bran, sawdust, cork, polystyrene... with a low density or products such as flours, oilcakes... ... with a higher density which don't flow naturally by gravity and have a tendency for "bridging". These machines are suitable for all kinds of silos (steel, polyester, concrete...) till 8 meters of diameter and are commonly used in round silos not exceeding 12 m in height. The output are spread out of 40 m3 / hour until 80 m3 / hour.
Working principles
An automatic feed tapered flight sweeps, from a central axis, the bottom of the silo and brings the product towards a central opening. The product is then handled by a vertical flight, which ejects it downward to the central outlet. The sweep action as well as the rotation of the flight are driven by two motors located under the floor
They offer the following advantages:
Reliability and performance : obviates "bridging" and compaction of products (first in, first out), allows more storage in a given place (eliminates hoppering), discharges the product in the center of the silo, secures a regular output, offers an easy access to mechanical components, even when the silo is full, guarantees a successful operation for several decades
Adaptable and robust + Option to regulate the speed, adjustable length of sweep flight (made in our own workshops from high quality wear resistant steel), adjustment to suit various products, quality manufacture, low maintenance
Optional: non-toxic white shellac
Security: suitable for use in Explosive Atmosphere and Conform to the European Norms.
