NOUFERROUS METALLURGICAL EQUIPMENT

In chemical, pharmaceutical, wastewater treatment, and hydrometallurgical projects, the use of filter presses for physical solid-liquid separation is one of the indispensable processes. Plate and frame filter presses have incomparable advantages in bulk material processing and separation of sticky and fine materials. After the plate and frame filter press action finished, the centralized discharge of the material will cause great pressure on the subsequent conveying system. In designing and actual production process, generally using controlling the process parameters of the materials, or increasing the power of the conveyor to ensure the continuous transportation of solid materials, improve the transmission efficiency, and avoid stacking and overload faults. In this article, through the example of modification demonstration in a project ‘iron and aluminum filter press’ process, to relieve the follow-up process pressure, and eliminate the overload fault by modifying the automatic control program of the filter cakes discontinuous discharge, for reference by similar enterprises in the case of reform needs.
