Research on how the granularity affected the liquidity and jet property of coal powder
WANG Xiu-ping
Abstract：this paper used powder comprehensive physical tester to do coal powder liquidity and jet property tests for different sizes of Lu’ an coal powder, it was shown that the liquidity index was in the range of 43.0 ~53.5, jet property index was in the range of 67.0~80.5, so the Lu’ an coal has bad liquidity and good jet property; the liquidity and jet property has inverse relationship, generally, the liquidity index decreased with the increase of proportion of particles whose size are smaller than 0. 075 mm, the jet property increased with the increase of proportion of particle whose size are smaller than 0.075 mm.
