A Comparison of Three Types of Coal Pulverizers
It pulverizes coal by applying hydraulically-loaded grinding pressure through three grin- ding rollers onto a rotating bed of coal. Grinding pressure can be adjusted to account for variations in coal grindability and desired product fineness. Raw coal is fed through a centrally located feed pipe to the center of the grinding table.

Investigation of water influence on coal based on thermal
In order to further understand the effect of the water content on spontaneous combustion of coal the thermal oxidative degradation kinetics of coals with different water contents were studied by Kissinger method Flynn–Wall–Ozawa method and Starink method. The results show that the water has no substantial effect on the thermal decomposition mechanism of the coal and reaction orders are
