Effect Of Moisture On Screen Efficiency

Effect Of Moisture On Screen Efficiency

Jul 26, 2015 The violent vibration and fluctuation is caused by the same thing. The build-up of material on the screen deck. Having this extra weight unbalancing the screen is like pushing a wagon up a hill. A lot of work until you get to the top, then the wagon will go like mad down the other side. That is what the electric drive motor is doing.
