Coal activated carbon strength teste

  Coal granular activated carbon test drum machine , Coal activated carbon strength tester coal activated carbon drum tester, also known as coal activated carbon strength tester, is developed in accordance with GB / T 7702
3-2008 test method for coal granular activated carbon strength determination
The instrument is a special instrument for measuring the strength index of coal granular activated carbon
Method summary: the sample is subjected to certain mechanical wear in the instrument, and the skeleton and surface layer are damaged at the same time
The damaged carbon particles are screened out, and the percentage occupied by the retained particles is calculated as the degree of the sample
