Belt Tensioning Methods for Small Package Conveyors

As shown in the figure below (Figure A), the tension on the belt is accomplished by turning the screw at the end of a conveyor. This pushes the bearing block towards the end of the conveyor, which adds tension to the belt. There is another, identical jack-screw located on the opposite side of the roller.


Screw Feeder Design for Metering Bulk Materials

Feb 20, 2018. Screw feeders are used in thousands of material handling applications and designed to meter bulk materials at a controlled feed rate. A standard screw conveyor is normally fed by another conveyor and the amount of material being discharged is directly proportional to the amount being introduced at the inlet.
