Improving Coal Pulverizer Performance and Reliability

pressure required to pulverize the coal. Raw coal enters the top of the pulverizer through the raw coal feed pipe. The raw coal is then pulverized between the roll and rotating ring. Hot air is forced in through the bottom of the pulverizing chamber to remove unwanted moisture and transport the coal dust up through the top of the pulverizer

Coal Preparation - an overview | ScienceDirect Topics

The feed has to be dried before it is conveyed to the feeding system. This is because high coal moisture in the feed can bind particles together and inhibit the flow of coal from the hopper to the pressure dispensing vessel, resulting in instability of the gasifiers (Dorminey et al., 2009).
