◆ Huasheng Screw Conveyor is used to deliver particle size of materials between 2 machines. There are pipe-type and u-type
     of Screw Conveyors to meet different requirements.Normally, we adopt variable speed control motor to adjust the feeding quantity
     according to the real production.
◆ Working Principle 
     They usually consist of a trough or tube containing either a spiral blade coiled around a shaft, driven at one end and held at the
     other, or a "shaftless spiral", driven at one end and free at the other. The rate of volume transfer is proportional to the rotation rate
     of the shaft. In industrial control applications the device is often used as a variable rate feeder by varying the rotation rate of the
     shaft to deliver a measured rate or quantity of material into a process.
