Williams Direct Injection Roller Mills are used as limestone grinding machines and can grind to very exact particle sizes that are required for efficient SO2 removal. These limestone mills are designed to operate at 3 to 4 PSI ( to bar) and 250°F (120°C) to inject the limestone directly into the Circulating Fluidized Bed (CFB), thus ...
The barite powder ultrafine vertical roller mill disc is driven by motor through reducer. The material falls to grinding disc from the feed opening. The materials are driven to the edge of the disc by the centrifugal force and crushed into fine powders by rollers. Then, the hot air from the nozzle takes the fine powder to a high efficiency ...
