Type of bag filter dust bag are made of many different types, the most common are polyester needle felt, high temperature fluorine US Sibu dust bags, etc. But if the angle, I know there are: centrifugal dust (unipolar whirlwind, Bipolar whirlwind, cast iron multi-tube, ceramic multi-tube, etc., efficiency is acceptable, lower operating costs, the most widely used), filter dust (bag type, membrane filtration, metal plates high filtration efficiency, but resistance is higher than large), electrostatic dust (high efficiency, but high operating costs), higher mill dust removal (efficiency, but hard to deal with waste water and dust), dust gravity low (efficiency, large area, mainly used in the larger dust particles) that variety is made with polyester fiber needle on polyester long 丝基布, using light pressure after singeing, stereotypes and other finishing processes, the filter has a high porosity, abrasion, folding, breathable and good, is a normal temperature filter materials are widely used. Broader application, I know that much. Another additional feature of dust, such as dust and other desulfurization. You can contact us train a professional production installation design
