Application and Advantages ofPulverized Coal. 2020-5-12 ·Pulverized CoalVerticalMill, also known asCoalPulverizer, is widely used incoalindustry, cement industry, stone industry, electric power industry, and other industry which is the large-scale material grinding and superfine grinding processing.
The heart of apulverized coal-fired boiler is the pulverizer, also known as themill. Depending on speed pulverizers are classified as low-speed, medium-speed, and high-speedmills.Pulverized coalburners may be located on the front or opposed walls or in the corners of the furnace.
