Coal Pulverizer - Pall

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 and out the exhaust pipe directly to the burner.

A Comparison of Three Types of Coal Pulverizers

Raw coal is fed through a centrally located feed pipe to the center of the grinding table. As the flat grinding table rotates, coal is gradually forced out towards the edge where it passes underneath the rollers. When the ground material leaves the edge of the table, it is met by an upward high velocity stream of hot primary air
