Ring Motor drive a grinding mill without contact between rotating and fixed parts. This concept avoids girth gear and pinions, which are used for conventional mill drives. The stator of the Ring Motor is wrapped around the mill as a ring. Due to the large size, the stator is fabricated and transported in segments. At site, the stator segments

1). A 2 pole (3600 RPM) motor with a 4quot; drive wheel will produce a surface speed of about 3700 sfm. 2). A 4 pole (1800 RPM) motor with a 6quot; drive wheel will produce a surface speed of about 2800 sfm. This is why 6 and 8 pole motors are not very useful without some countershaft ratio to up the speed.
Drive System Selection When a drive system is selected for grinding applications, a large number of items need to be checked and many questions must be answered. Depending on the mill size and type, the mill can be driven by several configurations of drive systems. The main options are single low speed motors connected to a pinion driving a

Grinding in small plants, as in larger installations, has proven to be the most costly of all unit operations from both capital and operating standpoints. Therefore, grinding deserves the most scrutiny of all operations during the design procedure. A recent survey by a major grinding mill manufacturer reveals that more than 80 autogenous or semiautogenous mills having between 100 and 1,000

The first step in slag processing is size reduction to liberate metallic iron and ironbearing minerals. This is done by crushers or by autogenous grinding, that is, the slag is ground on its own in the grinding mill without any balls. The latter process yields higher quality product as the iron product discharged from grinding mill contains as high as 80% Fe (Shen and Forssberg, 2003).
Mill drive selection for semiautogenous grinding mills Dan B. Kivari and John Chapman A key operation of any milling circuit is grinding. Over the last two decades, large diameter semiautogenous grinding (SAG) mills have become the preferred primary grinding mills. The drive systems became more complex as the size of the mills became larger
Our GMD eliminates all mechanical components of a conventional mill drive system, such as ringgear, pinion, gearbox, coupling, motor shaft and motor bearings: By mounting the rotor poles directly onto the mill, the mill itself becomes the rotor of the gearless motor.
In centerless grinding, the workpiece rotates between a grinding wheel and a regulating drive wheel. The work is supported from below by a fixed workrest blade. The two basic modes of centerless grinding are quot;thrufeedquot; and quot;infeedquot; or quot;plungequot; mode. In
