Similar to the ring and ball mill, the vertical spindle roller mill uses large "tires" to crush the coal. These mills are usually found in utility plants. Raw coal is gravity-fed through a central feed pipe to the grinding table where it flows outwardly by centrifugal action and is ground between the rollers and table.
Mill sealing. Seal air fans are provided to keep the fine dust from leaking from the casing. They are usually designed for 150-200 mm wg above mill inlet air pressure. Milling Plant Mill sizes • The nominal diameter of the ring or racer or wheel is the prime dimension in a mill.

Section Mills Section mills are primarily used to mill sections in the casing for: Sidetracking, gravel packing, and/or perforation zones. Eaton''s section mills are available in a variety of OD sizes, ranging from 3 1/4" to 9" O.D.''s. The blades are dressed so that all blades simultaneously mill the casing, with the milling rates usually
Its advantage over section milling is that less cutting debris needs to be circulated out of the well. The need for a larger casing window. Performing a casing exit to create a secondary wellbore involves a whipstock assembly to direct the mill toward the side of the existing casing, where an exit is then milled.
The targeted fleet for this 34.5-inch low-pressure section upgrade contains the numerous GE units that utilize the original 30-inch LSB design in 2-, 4- or 6-flow low-pressure casing designs. Most of these turbines are over 30 years old and utilities are depending more and more on these workhorse units. (See Figure 1.) Steam Turbine 34.5-Inch
