Scope of application: Granular activated carbon performance characteristics: steel cylinder speed: 50 ± 2r / min, easy to operate. Power supply: AC 220V Appendix: Operation steps: 1. Column charcoal operation steps: 1. Take 100g sample, place it in the standard sieve with the smallest sieve size in the particle size regulation, sieve it on the vibrating sieve for 5min, take the sieve The upper sample was dried to a constant weight in a 140 ± 10 ° C constant temperature oven. 2. Take 50mL dry sample from the measuring cylinder, weigh it, put it into the No. 2 steel cylinder, put 5 steel balls, cover the lid, start the instrument, and record the time, run 5±0.08min. 3. Remove the steel cylinder, open the cylinder cover, pour out the steel ball, move the sample to the original standard screen, and sieve it on the vibrating screen for 5 min. 4. Collect the sample remaining on the sieve layer and weigh the mass. Second, the amorphous carbon powder operation steps: 1, take 100g sample, placed in the standard sieve of the minimum size of the sieve size of the variety, sieved on the vibrating screen for 5min, take the sieve on the sample at 140 ± 10 Dry to constant weight in a constant temperature oven at °C. 2. Take 50mL dry sample from the measuring cylinder, weigh it, put it into the No. 1 steel cylinder, put 10 steel balls, close the lid, start the instrument, and record the time, run 5±0.08min. 3. Remove the steel cylinder. 4. Open the cylinder cover, pour out the steel ball, move the sample to the original standard screen, and sieve it on the vibrating screen for 5 min. 5. Collect the sample remaining on the sieve layer and call it the mass. Standard: GB/T 12496.6-1999 Note; if you want GB/T 7702.3-2008
