Bulk material handling applications – comprising both mechanical systems (screw conveyors, bucket elevators, chain conveyors…) and also pneumatic systems (conveying using air pressure and by vacuum, fluidized bed chutes…). Depending on the type of applications, some factors that influence the selection of suitable mode of handling includes, characteristic of material, distance, accuracy of conveying, limitation of space, hygiene requirement, integrity of material after conveying, power consumption etc., has a very strong impact on production and productivity. The system selected should provide a reliable, safe and predictable way of transportation without human intervention as far as possible.
