How to distinguish the quality of activated alumina desiccan

1. Strength test of activated alumina balls:
Under normal circumstances, the strength of activated alumina should reach 85N or more. Only when this indicator is reached, the activated alumina ball can reach the normal service life, otherwise the service life is very short.
2. Detect the appearance of activated alumina balls：
The crushing rate should be controlled below one percentage point. The crushing rate of general products is about 0.6%. If the crushing rate is too high, the use of the entire air compressor will have a certain impact.
1.The specifications of activated alumina balls should be unified.
Due to the particularity of the air compressor, the specification error of the activated alumina ball must be within 1 cm, and the specification fluctuation exceeds the standard, which will affect the operation of the air compressor
