What is a Chinese medicine powder slap screen?

Chinese medicine powder slap sieve is used for particle size analysis, impurity separation or screening process of Chinese medicine powder. Through the combination of mechanical slapping and vibration, the Chinese medicine powder can be evenly distributed and effectively separated from materials of different particle sizes, ensuring that the fineness and uniformity of the powder meet the standard requirements, thereby achieving grading or screening.

Applicable materials for the Chinese medicine powder slap screen

1. Various Chinese medicine powders: including powders ground from various Chinese medicinal materials such as rhizomes, fruits, seeds, and whole herbs.

2. Other fine powders: In addition to Chinese medicine powders, the slap screen is also suitable for other fine powders that need to be graded.

The difference between Chinese medicine powder slap sieve and Chinese medicine powder test sieve

① Chinese medicine powder slap sieve

Function: Chinese medicine powder slap sieve is mainly used for screening and filtering of Chinese medicine powder. It is screened by vibration and impact to remove impurities and adjust the particle size of Chinese medicine powder.

Features: Vibration and impact action, fast and effective screening of Chinese medicine powder.

Application: Suitable for large-scale Chinese medicine powder processing, used for screening operations on production lines.

② Chinese medicine powder test sieve

Function: Chinese medicine powder test sieve is used for laboratory screening and analysis of Chinese medicine powder, usually used in the research and development stage to determine the particle size distribution and screening effect of the powder.

Features: Used for test screening of small batches of Chinese medicine powder to evaluate particle size distribution and screening performance.

Application: Suitable for scientific research, development and quality control to determine the best production parameters and screening process.

Features of Chinese medicine powder slapping screen

✅ Suitable for difficult-to-screen Chinese medicine powder: such as ultra-fine powder, easy to adhere, static electricity, and hygroscopic Chinese medicine powder (such as pearl powder, Ganoderma lucidum spore powder).

✅ Optimized specifically for the Chinese medicine industry: avoid the loss of activity or effective ingredients of Chinese medicine powder due to excessive vibration.

✅ The particle size is uniform after screening, which improves the quality stability of Chinese medicine preparations (such as granules, capsules, tablets).

✅ Modular design: Different screen layers, materials (stainless steel 304/316L) and other configurations can be selected according to needs, with a high degree of customization.

Recommended mesh number for Chinese medicine powder slapping sieve

1. Ultrafine powder (ultrafine powder, high-precision screening is required)

Material	Recommended mesh number (mesh)	Features
Pearl powder	300-500 mesh	Very fine particles, ultra-fine screening is required
Ganoderma lucidum spore powder	200-400 mesh	Light and easy to float, high-precision screening is required
Panax notoginseng powder	120-300 mesh	Particle size needs to be controlled to prevent excessive coarseness
Cordyceps sinensis powder	120-300 mesh	More fibers, need to be properly crushed and screened
American ginseng powder	100-200 mesh	Fine particles, need to be evenly distributed

2. General powder (conventional Chinese medicine powder, moderate particle size)

Material	Recommended mesh	Features
Astragalus powder	80-150 mesh	The fiber is relatively long and easy to block the screen
Codonopsis powder	80-150 mesh	The powder is loose and easy to screen
Angelica powder	60-120 mesh	Need to screen to remove coarse fiber
Chuanxiong powder	60-120 mesh	Uniform particles, often used for powder preparation

3. Granules (preparation powder, tablets or granules pretreatment)

Material	Recommended mesh	Features
Chinese medicine granule powder	40-80 mesh	Suitable for granule screening
Broken wall Panax notoginseng powder	80-150 mesh	Need to control the fineness to avoid ultra-fine affecting the taste
Chinese medicine slice powder	60-100 mesh	Suitable for tablets, granules, etc.

How to choose the right mesh?

Ultrafine powder (200 mesh and above): suitable for ultrafine powder, such as pearl powder, Ganoderma lucidum spore powder, etc.

Medium fineness (80-200 mesh): suitable for most Chinese medicine powders, such as Panax notoginseng powder, Astragalus powder, etc.

Coarse screening (40-80 mesh): suitable for screening of Chinese medicine powder and granules.
