What factors are related to the working efficiency of the filter press

High efficiency is the goal that an enterprise always pursues in production, and efficiency is the most direct factor that directly affects the economic benefits of an enterprise. The same is true for filter presses. So what factors in the work of filter presses will affect filter press efficiency? The following Su Dong analyzes for you from a professional perspective:


1. What is the mesh level content:

The content of -200 mesh in the feed directly affects the filter press effect. The larger the content of -200 mesh, the lower the processing capacity of the filter press and the higher the moisture content of the filter cake. If the feed size is relatively coarse, although its filtration performance is good, the cake-forming time is short. However, the feed size is too coarse, the slime settles quickly, the fluidity is poor, the center hole of the filter press is prone to blockage, and the resulting filter cake is loose.


2. Feeding concentration and pressure:

The higher the feed concentration, the shorter the time required for the filter press to fill the filter chamber with coal slime, the stronger the processing capacity of the filter press and the lower the moisture content of the filter cake. Although a higher feed concentration is beneficial to the improvement of the filter press effect, the feed concentration should not be too high. Generally, the feed concentration is required to be above 300g/L, preferably around 500g/L, and the highest should not exceed 800g/L. The higher the feed pressure, the lower the moisture content of the filter cake. If the pressure is too high, although it helps to shorten the cake forming time and reduce the water content of the filter cake, the effect is not significant. Generally, a feed pressure of 0.4-0.8MPa is a good condition.


In summary, the working efficiency is related to the solid content in the filtrate of the filter press, the feed concentration, the feed pressure, and the feed particle size composition. In addition, the filter press time needs to be controlled. The longer the filter press time, the lower the moisture content of the filter cake. However, the filter press time directly affects the processing capacity of the filter press, and it shows that the filter press time is too long, and the moisture reduction of the filter cake is not obvious. Therefore, everyone should choose the filter press time according to the actual situation while following the operating specifications.
