Langling Intelligent has high requirements for precision grinding and dispersed grinding in order to achieve micron level absorption of materials in the food, pharmaceutical, and cosmetics industries by the human body. Grinding this type of product requires the use of food grade sand mill materials. The grinding chamber in contact with the material uses zirconia ceramic rotors, liners, end caps, and even mechanical seals need to be made of zirconia ceramic materials. Commonly used nanoscale sand mill equipment to determine the purity, fineness, and stability of the finished product after grinding.
