3 PRINCIPLE OF THE METHOD

After a certain size range and quality calcined petroleum coke, conditions after grindability tester ground in a predetermined sieve, sieve material weighing quality. Obtained from a standard sample after grindability index curve calcined petroleum coke grindability index.

4 Definitions

Hastelloy grindability index (HGI) Hardgrovegrindabilityindex After relatively easy to determine the pulverized calcined petroleum coke grindability index by comparing the standard curve. HGI higher the value, after calcined petroleum the easier coke mill.

5 Instruments

6 Sampling

After carbon anode calcined petroleum coke according to GB/T 26297.6 sampled.
