When working, the suspension to be separated (or the material that needs to be deliquored, the finished article) will be added to the centrifuge drum with filter media. Under the action of the centrifugal force field, the suspension moves to the wall of the drum. Among them, the solid particles are blocked by the filter medium and retained to form a filter cake layer; while the liquid and some of the finer particles pass through the gap between the filter medium and the filter cake, and are discharged from the drum through the small holes opened on the drum. The separation of solid and liquid phases is implemented. According to different separation processes, after the filter cake layer is formed, washing and replacement liquids can be added to wash and replace the filter cake, and then perform the final spin-drying and deliquoring separation until the separation requirements are reached, and the speed is reduced or mechanically Stop, use manual or mechanical means to unload the filter cake from the drum.
