Ultrafine screen mesh has a wide range of applications, covering almost all industries that require fine screening. In the production process of Chinese medicine powder and other pharmaceutical products, ultra-fine sieve mesh is used for sieving and grading of powdered raw materials to ensure the quality and purity of drugs. In the process of food additives, flour and other food raw materials, ultrafine sieve mesh is used to sieve flour, remove impurities, improve the taste and quality of food. In the screening and filtration of chemical raw materials, ultra-fine sieve mesh can separate the fine particles in the material to ensure the purity and uniformity of the product. In the field of waste water treatment, air purification and other environmental protection, ultra-fine sieve mesh is used to filter out the tiny suspended particles and particulate matter, purify water and air.
