I. Core Performance Indicators
1. Grinding Fineness
Standard models (80-200 mesh) are suitable for conventional medicinal materials, while ultra-fine grinders (2000 mesh and above) improve the dissolution rate of active ingredients through airflow technology.
Testing method: Observe the uniformity of particle distribution using a laser particle size analyzer or microscope.
2. Working Efficiency and Energy Consumption
Compare the grinding quality per unit time with the theoretical value; energy consumption must meet industry standards (e.g., a 2500-watt model's continuous operation energy consumption ≤ 1.5 kWh/hour).
II. Verification of Actual Effects
1. Sample Testing
Select standard medicinal materials (such as Panax notoginseng) to test grinding efficiency, observing whether there are residual clumps or incompletely crushed particles.
For medicinal materials containing sugar or mucilage (such as Asparagus), the anti-sticking design effect needs to be tested, and the loss rate should be less than 3%.
2. Temperature Control
For heat-sensitive medicinal materials (such as Dragon's Blood), the grinding chamber temperature needs to be ≤ 50℃ to avoid degradation of active ingredients.
III. Equipment Stability and Safety
1. Continuous Operation Test
Monitor performance fluctuations (such as noise and vibration) during long-term operation; abnormal values must be lower than industry standards.
2. Safety Protection
Emergency stop buttons, grounding devices, and other functions must be in good working order; the lid-opening power-off design reduces operating risks.
IV. Cleaning and Maintenance
The residue rate after grinding should be less than 5%, and the sieve screen deformation rate > 15% requires replacement.
