Why 316 material is commonly used for GMP vibrating screen

With the development of science and technology, the pharmaceutical industry has a comprehensive standard for raw materials, production process and sales channels, especially for the production process, import treatment has strict requirements for the production process For Chinese and Western medicine, a series of equipment used from raw material selection, to grinding, screening, and finished product packaging must be environmentally friendly, and the material must meet the relevant regulations The material of shaker is also divided into carbon steel, 304 stainless steel, 316L stainless steel and special plastic material Chemical industry or no special requirements for the use of carbon steel material can not only meet the screening needs of customers, but also reduce production costs for customers However, if food and medicine materials are made of stainless steel, there are more and more users using 316 materials, mainly for the following reasons: 1 The raw materials of pharmaceutical powder have high requirements for materials During the production of pharmaceutical powder, it is required not to be polluted Therefore, the material requirements of the machine are high, which must be stainless steel or above 2 Stainless steel vibrating screen In terms of production process, there are very fine designs for welding, grinding and other fine engineering design For example, the grinding process of rotary vibrating screen of ordinary carbon steel material needs to be completed in one hour, but the operation of stainless steel material may take three hours or even longer to complete in the grinding process, so the screening and use of the material for pharmaceutical powder will not cause pollution to the raw materials 3 The nickel content of 316L material is higher than that of 304 material, so its rust resistance is better, and the material contains Mo element, so it has stronger acid-base corrosion resistance Therefore, more than 95% of the raw materials of the medical vibrating screen will be made of 316L In the pharmaceutical production process, there is a very high demand for the powder particles and quality If the pharmaceutical powder contains impurities or oversized particles, it has a very important impact on the quality of products Therefore, the use of vibrating screen is a very important link in the pharmaceutical production process
