Screw conveyors are mechanical devices used for the bulk transportation of materials in a helical, or screw-like, manner. It consists of a rotating spiral blade, or helix, enclosed within a tube, which effectively pushes or pulls materials as it rotates. Screw conveyors are widely employed across industries like agriculture, food processing, construction, and wastewater treatment for various purposes, such as moving grains, powders, bulk solids, and even liquids. Their key advantages include efficient material handling, versatility in accommodating different materials, ease of maintenance, and the ability to operate in various orientations (horizontal, inclined, or vertical). Screw conveyors are appreciated for their reliable and continuous operation, making them an essential tool in streamlining material transportation and processing operations.
