Plow Dischargers

The plow dischargers are simple and are easy to maintain. Normally are located under a conical silo or traveling under a long stockpile. As the plow rotates, it pushes the solids, and loosens the solid above it and the discharge occurs. In some cases, two plows are used. One of the disadvantages of the plow feeder is the dead zone that can extend along the wall since the penetration of the plow falls short of the silo wall. In order to circumvent this, the hopper design at the interface of the plow must include either a straight part or the plow length has to be longer than the hopper part. In order to overcome the dead zone at the central part, a cone insert has to be designed properly.
