The application of three-dimensional rotary vibrating screen in the pharmaceutical industry

The pharmaceutical industry has high hygienic requirements for screening machines, so stainless steel three-dimensional rotary vibrating screens are widely used in this industry. The following will introduce some application scenarios of three-dimensional rotary vibrating screen in the pharmaceutical industry:

The three-dimensional rotary vibrating screen is usually used in the pharmaceutical industry to screen traditional Chinese medicine powder, raw materials, Chinese medicine formula granules, pellets, Chinese medicine pills, Chinese medicine decoction pieces and other pharmaceutical raw materials. The screening conditions and screening requirements of each raw material are also different:

The three-dimensional rotary vibrating screen can sieve powders as fine as 500 meshes, and can meet the grading and sieving of traditional Chinese medicine powders and APIs.

The number of screen layers can also be used flexibly. The single-layer screen can be used to filter and remove impurities from the pharmaceutical raw materials, and screen out the powder, soil, fiber, large-grained medicinal materials, and adhesive medicinal materials. Classification of pharmaceutical raw materials (up to six levels) to meet the application needs of drugs with different characteristics.

Because some Chinese medicine pills and Chinese medicine formula particles are wet or easy to stick together, Chinese medicine powder and raw materials are too fine to cause mesh blockage. 

The mesh cleaning device of three-dimensional vibrating screen can be selected to solve the problem of mesh blockage caused by medicinal materials.

The three-dimensional rotary vibrating screen adopts a special grid setting, which not only prolongs the service life of the screen, but also makes it easier to change the screen (3-5 minutes).

Food-grade silicone seals are preferred to prevent contamination of the screened pharmaceutical raw materials.

Screening benefits:

Different types of rotary vibrating screens have different yields for filtering and screening pharmaceutical raw materials. The larger the model, the greater the screening output. Generally speaking, the screening output of the rotary vibrating screen can range from 50kg/h to 2000kg/h.

Due to the different screening purposes and the mesh size of the screen, the screening output will also vary. For example, pellets and Chinese herbal decoction pieces are generally only used for impurity removal due to the large mesh size of the screen. The screening output and screening efficiency will be higher than other powdered and graded pharmaceutical raw materials. The following is the processing capacity table of the three-dimensional rotary vibrating screen for reference:

Note: The processing capacity in the table is dry screening, the screen is 4 mesh, and the material is the tested value under the screening conditions of large sand.
