The related problems of vibrating screen in the application of pharmaceutical technology, the vibrating screen for the pharmaceutical industry plays the role of screening to achieve the particle size of qualified materials in the screening of powders. It is a special industry for the production of medicines. There are also relevant regulations in the Pharmacopoeia.

The unit operation of classifying the material particles according to the particle size by a sieve is called sieving.

After the raw materials are pulverized, the particle size of the particles is not uniform, and it is necessary to perform sieving before mixing. In the pharmaceutical production process, the tool used for screening is a standard sieve. China's drug screens are made according to Taylor's standard standards. The Taylor standard is the name of the screen containing the sum of a hole diameter and a wire diameter per square inch (approximate number) plus the unit mesh, such as a sieve with a total of 100 individual apertures and a single wire diameter per inch length. It is called a 100 mesh sieve.

Common screening machines are circular vibrating sieving machines and electromagnetic vibrating sieving machines. Two unbalanced weights are mounted on the drive shaft of the motor. The upper weight causes the horizontal movement of the mesh screen, and the lower weight causes the sand net to move vertically, thereby synthesizing the three-dimensional vibration of the screen. The material falls into the center of the screen. After sieving, the coarse material on the screen surface is discharged from the outlet, and the sieved material is discharged from the lower outlet. The diameter of the screen is generally 0.4 to 0.5 meters, and each can be made of one to five layers of screen.

In order to be more in line with the health and safety of the pharmaceutical industry, we use all stainless steel materials to create equipment. If there are special requirements, we can also provide plastic materials to further improve the safety level.
