Aug 29, 2010 Bowl mills are used for pulversing coal in pulverized coal fired boilers. The coal to the mill is fed by a coal feeder from the coal bunker. There are many type of feeders used for coal feeding like the belt feeder which can be in volumetric or gravimetric mode, the chain link feeder, the drag feeder, etc. Row coal from the yard is sized in crushers and stored in coal bunkers.

Aug 29, 2010 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.

Nov 23, 2013 TYPES OF MILL • Tube or ball mills: These are low-speed machines that grind the coal with steel balls in a rotating horizontal cylinder. • Vertical spindle mill: These are medium-speed machines that include bowl mills, ring roll mills, and ring and ball mills. The bowl mills are further divided into deep bowl or shallow bowl mills.

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
