• Limestone Mill Grinding Machine Fluidized Bed

    Williams Direct Injection Roller Mills are used as limestone grinding machines and can dry to very exact particle sizes that are required for efficient SO2 removal. These limestone mills are designed to operate at 3 to 4 PSI (0.2 to 0.3 bar) and 250°F (120°C) to inject the limestone directly into the CFB thus eliminating costly material handling storage and drying equipment.
