How to Choose the Right Filter Cloth?

Material selection: Different filter cloth materials have different performances in applicable working conditions. When choosing filter cloth, we should consider the characteristics of the material to be filtered, such as material temperature, abrasion, corrosion, and so on.

Filtration precision: Filtration precision is an important performance index of the filter cloth, which determines the solid-liquid separation effect and efficiency of the filter press. Too low a filtration precision will cause fine particles to penetrate the filter cloth and affect the filtration effect, while too high a filtration precision means that the resistance of the filter cloth will lead to a reduction in filtration efficiency. Therefore, it is extremely important to choose suitable filtration precision according to the size of solid particles in the material and the viscosity of the material.

Cake discharging effect: Cake discharging efficiency would be affected by the granularity, viscosity, and specific gravity of different materials. Based on satisfying the filtration effect and efficiency, choosing the right filter cloth will bring convenience into cake discharging, thus reducing labor work and cost and improving the efficiency of the filter press.

Experimental verification: After determining the preliminary range of suitable filter cloth, it is necessary to verify the actual effect of the selected filter cloth by conducting filtration experiments on the materials. In the experimental process, it should be ensured that the basic characteristics of the material are highly consistent with those in the actual industry production, to obtain accurate experimental results.

In addition, the size and cutting precision of the filter cloth, sewing strength, fixing method, and waterproof treatment of the feeding area (using anti-permeability abrasion-resistant material or glue treatment) are also factors that should be taken into consideration when choosing filter cloth. XUDA Filtration has purchased several CNC laser cutting machines and hired experienced filter cloth sewing workers for the convenience of our customers' purchase of filter cloth. Summarizing years of experience in the filtration industry, we have selected 56 commonly used filter cloths and made a sample booklet, which records the detailed parameters and applicable industries of each filter cloth, we are willing to send you this booklet free of charge if you have a long-term need for filter cloth!
