Screw Conveyors are one of the oldest and simplest devices used for the movement of bulk materials. Screw conveyors are compact and easily adapted to congested locations. They can be used as a mixer or agitator, to mix and blend dry or wet ingredients. Screw conveyors are available in a wide variety of materials to resist corrosion, abrasion or heat. Horizontal, inclined, or vertical conveyors are also available.
