Plate and frame diaphragm chamber filter press operation process common problems and treatment
2024/07/29 590
In the coal gasification industry, the gasification filter cake is usually blended into the power coal for blending and use, but because of the high water content of the filter cake, direct blending will cause power coal plugging. In order to reduce the risk of power coal blending and plugging, it is necessary to further reduce the water content of the filter cake. Plate and frame filter press can reduce the water content of filter cake very well, so to ensure that the plate...
