The dust removal bag of the polishing mill is a type of filter bag used for dust purification in processes such as polishing, grinding, and polishing. The selection of dust removal bags for polishing mills should be determined based on the specific conditions of the process and the characteristics of the dust. Usually, the dust removal bag of the polishing mill needs to have high filtration accuracy, good wear resistance, and high tensile strength to meet the requirements of high-strength use. At the same time, it is also necessary to consider the matching of the filtering area of the cloth bag and the processing air volume to ensure the effectiveness and operational stability of the dust removal system. In addition, it is also necessary to pay attention to the replacement cycle and cleaning method of the cloth bag to ensure dust removal effect and bag life.
