Robust shaftless spiral conveyors

New opportunities are opening up for the use of RATAJ RL and RLN robust shaftless spiral conveyors for more demanding application in heavy industry or for high performance requirements (from 0.01 to 600 m³ per hour). Robust conveyors can easily tackle the transfer of abrasive materials (ground corundum, grit, sand, crushed stone, abrasion dust, building materials, fly ash, etc.), materials with a high grain factor (canisters, PET bottles, books, wood chips, etc.), and adhesive and wet materials (sludge, earth, etc,); used correctly, they can help find solutions to problems that had previously left the customer in despair. Because our robust shaftless spirals are of such high quality, we can design pull conveyors (the traditional solution) and push conveyors (direct feeding into boilers and furnaces, dispensing via several conveyors at once into a single hopper, etc.).
