Vacuum grinding

Vacuum grinding involves removing air from a sealed container and crushing and mixing samples using grinding media. This method prevents sample oxidation and moisture effects, making it suitable for processing volatile or air-sensitive materials. It is commonly used in industries such as coatings and plastics for sample preparation before testing.
Selection
When selecting, consider the sample characteristics; materials prone to oxidation require equipment with good sealing. Match the grinding intensity according to particle size requirements, and observe whether the equipment material is corrosion-resistant. Pay attention to the compatibility of container capacity with sample volume, and check the air extraction efficiency of the vacuum pump. Balance operational convenience with maintenance costs.
