The solid screw flight rotates without a central pipe in a wear resistant trough. This prevents material build up or wrapping.<\/p>\n<p data-start=\"403\" data-end=\"793\">The shaftless screw conveyor can be configured horizontally or inclined. By varying the diameter, pitch and rotational speed, the shaftless screw conveyor can be adapted to a wide range of conveying applications. The shaftless spiral conveys material continuously or in a metered flow for weighing or for controlled product feeding to, for example, a mixer, silo or subsequent process step.<\/p>\n<h2 data-start=\"795\" data-end=\"834\">Application shaftless screw conveyor<\/h2>\n<p data-start=\"836\" data-end=\"1077\">The shaftless screw conveyor is used in installations where product behaviour affects the continuity of the conveying process.
