Wood activated carbon strength testerPrinciple:

The sample undergoes certain mechanical wear in the instrument, and both the skeleton and surface of the sample are damaged. After screening, the percentage of retained particles is calculated as the strength of the sample.

Wood activated carbon strength testerParameters and equipment compatibility:

1. Sample sieve: Take the smallest sieve number specified for the activated carbon of this variety.

2. Vibration screening machine: The vibration frequency is about 221 times/min, and the vibration frequency is about 147 times/min.

3. Stopwatch.

4. Strength tester parameters:

a) Steel drum speed (50 ± 2) r/min
