Coal Hang-up in Bowl Mill Operations - Bright .

There are many types of mills and bowl mill is one of them, all these mills can face coal hang-up. For taking corrective action during a coal hang-up in bowl mills the operator will have to know the reason for such a hang-up, how the plant will respond, what he has to respond to and what the local operator will have to do. This will reduce the chance of mill trip and bring back boiler to ...

Check your mill to confirm that the grinding roll or spring frame preload pressure is set correctly. Our experience with both RP and MPS pulverizers has been that mills designed for a throughput of about 120,000 pounds of coal per hour, an HGI of about 45 to 50, and coal fineness exceeding 75% passing 200 mesh will require about the same force on the grinding elements.
