Coal ball mills in power plant process flow

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. Coal that has not been pulverized into fine enough particles cannot be blown out of the top of the unit; it falls back to the ring and roll to be further pulverized. Ball Coal milling have been used across a wide range of industries and applications, such as paints, pigments, pharmaceuticals, ceramics and coal slurries. The attrition mill could be considered on the other end of the loose generic description of stirred media or stirred ball mills. Similarly, some have classified the vertical ball mill as being in the family of attrition mills.
