Optimal Application of Angular Feed Filter Press in Hydrometallurgy
In order to continuously optimize the production process,a company has added two 350 m2 program-controlled angle feed diaphragm filter presses in the wet workshop.However some problems have been found in the commissioning,such as the cracking of some diaphragm plates,the high moisture content of filter cake and the high manual operation intensity.In order to ensure the efficient operation of the filter press,further optimization was carried out.One is the optimization of the filtration process;the second is the optimization of filter press control system;the third is the optimization of the clamper;the fourth is the optimization of the backwashing liquid prod.After the system is optimized,the filter press is re-filtered.The thickness of the filter cake is basically the same,and the water content index of the filter cake is kept below 28%.The overall effect is good.
