A Comparison of Three Types of Coal Pulverizers

pacted on a grid section by swing hammers, reducing the coal to a nominal 1/4" size. Drying of the coal also occurs in this section. After the coal passes through the grid section, it enters the two-stage pulverizing sec- tion. This section further reduces the coal size by attrition and by impact of coal on the moving and stationary parts.
