This paper describes a study of the transportation of pulverized coal. The results showed that this cannot be evaluated exactly by rest angle, but by the injection amount per unit time. The transportation characteristics of pulverized coal are related to the variety and nature of the finished coal. Pulverized coal with homogeneity and larger granularity has better transportation characteristics.
Pulverized coal with close grindability index is the preferred choice when adopting mixing injection.
