  • Moving difficult-to-handle bulk materials with flexible screw conveyors

    Flexible screw conveyor systems can be engineered to transport bulk materials that tend to pack, cake, smear, break apart or fluidize, and can prevent the separation of blended products. Flexible screw conveyors (Fig. 1) are suitable for most bulk materials, from sub-micron powders to large pellets, both free-flowing and non-free flowing. They are capable of conveying bulk materials at any angle ...
