The pharmaceutical processing procedure starts with the pretreatment of Chinese medicinal herbs and raw pharmaceutical materials to remove sediment, fibers, agglomerates and various impurities, followed by crushing, extraction and granulation to produce semi-finished materials. Different pharmaceutical dosage forms require precise screening processes, such as sorting intact medicinal leaf fragments, classifying raw pharmaceuticals by particle size, and filtering ultra-fine medicinal powder to meet the production standards for tablets, capsules, powders and granules. At this stage, vibrating screens are adopted to complete grading, impurity removal and filtration operations.
Common screening mesh range for pharmaceutical use: 10–600 mesh. Xianfeng recommends vibrating screens:
