What about the key points for selecting flour mesh?...

In the daily industrial production of filter press, our most common problem is how to choose the bolting cloth that is suitable for our own industry and how to choose the bolting cloth of different types of filter press. We talk about these problems today.

In general, we are choosing the chamber filter press according to our requirements and the nature of the filter, ie the stripping, chemical and physical properties of the material; the filter cake drying after filtration; Wait, we will explain this one by one.

First of all. The most important thing for us is to consider the nature of the material being filtered. Its factor is more than 75% of the importance of selecting the bolting cloth fabric filter.

A. The stripping performance of the filter residue, it directly reflects the working efficiency of the filter press equipment. The surface of the filter residue is smooth and non-adhesive, and the filtrate will be rapidly leached out from the middle bolting cloth. The filtering time period is high and the efficiency is high. On the contrary, the filter residue has blocking properties and the filtering time will be long, and the efficiency will naturally be reduced accordingly. Moreover, the stronger the blocking, the lower the efficiency. At this time we will choose monofilament or satin weave cloth.

B. According to the chemical nature of the filtrate, such as acidity and alkalinity, different acid-base levels are suitable for the type of bolting cloth. The strongest acid resistance is polyester filter cloth, and the strongest alkali resistance is vinylon bolting cloth. Acid and alkali resistance is also polypropylene bolting cloth.

C. The shape of the filter residue, whether the particles are uniform, and whether the shape is hard, so as to consider the abrasion resistance of the bolting cloth. Uneven size, there are water chestnut, depending on the degree of choice. The best wear resistance is strip filter cloth and polyester filter cloth.

D, the temperature of the filter, the temperature is also affecting the filter cloth filter and work efficiency. The highest temperature resistance is strip bolting cloth.

Again, it is our requirement. We hope the efficiency of the filter press and the degree of drying of the filter residue. Bolting cloth regeneration performance. When selecting the Bolting cloth, it is also necessary to select a bolting cloth with good regeneration performance. The bolting cloth with good regenerative performance can directly wash the filter cloth on the filter press, reducing the number of cloth change. Replacement bolting cloths can be restored to more than 80% by simple treatment (drying, washing, etc.).
