Spiral sheets - Import export

Screw conveyors are used to transport grains and powder materials on the horizontal axis. Spiral sheets of different sizes are used depending on the purpose of use. Full spirals are used for transfer purposes only. We produce screw conveyors with capacities ranging from 5 tons/h to 500 tons/h.

It collects the flour from all exits of the sieve and delivers it to the flour container via pneumatics. Flour inlets are made with separate flour inlet valves. The valves lower the incoming flour into the spiral part. From here, it is directed to the outlet section via a spiral. Since the flour is covered with hair on the spiral, dust formation is prevented. There are ventilation holes at a certain point in this closed sheet metal. The spiral legs are made of rectangular profile. The helix of the gearmotor is located on the side of the outer body and is fixed to this side with the motor stand. There are rubber inspection covers on each flour flap.

Back in 1931 the history of an inimitable brush began: Kullen-Koti was already the patentee for this spiral brush with a double-sheet backing tape. Since then we have been developing this brush type and have manufactured the most variations. But one thing always remained the same: the double-sheet backing tape. Because of our experience, this system is the most effective and safe method. See our illustration which shows you the construction. Available brush sections: We manufacture our spiral brushes with four different section types in backing widths (WB) ranging from 4 mm to 18 mm. According to your requirements we choose the appropriate backing width considering the essential parameters: core diameter, fill material, fill density and working conditions. We supply backing tapes in bright steel as well as galvanised steel or stainless steel and acid/heat-resistant steel quality 1.4301, 1.4571, and 1.4541 (AISI 304, 316Ti) Manifoldness The roller brush coils with roller core are...
