The so-called feeding pressure usually refers to the slurry pressure of the feed pump when the filter press is working. The feeding pressure required for different filter cloths, different slurry concentrations, and different ore particle fineness is different.
First, when the ore is fine and the concentration is very low, high pressure and high flow rate are required. Through high pressure forced filtration, small ore particles can be concentrated into cakes and the feeding time can be shortened, but the strength of the filter cloth needs to be increased.
Secondly, when the ore particles are not very fine and the slurry concentration is very high, the flow pressure needs to be balanced to give the machine a smooth and continuous filtering process. This can shorten the entire filtration cycle time and achieve satisfactory working results.
If the pressure flow is too large, it will have a counter-effect. The slurry is forced to hit the filter cloth and cannot fall off automatically, thereby extending the entire working time and increasing the operating intensity.
