The oxidation of sulphur dioxide to sulphur xide is a reversible process. The pressure is maintained at 1.2-1.5 atm and temperature at 410-430°C. If the temperature rises above 430°C then the equilibrium is displaced away from Sulphur xide, hence it is very important that operating temperature should be maintained in this range.

Because the grinding process creates a lot of heat, flood coolant is most appropriate. However, it is equally important that the fluid be delivered where it is needed the most: at the point of cut. "The application [method] of the fluid is very important; it should apply the fluid to the interface where it is needed the most," said Foster.
The fact that sulphur filled the grinding wheel pores, to a large extent guarantees that the grinding wheel dressing, conditioning and sharpening procedures would not have significant influence on the proportions of sulphur in the grinding process. Download : Download full-size image Fig. 2.
The grinding process is truly a chip producing machining process. The rough surface of the abrasive wheel spreads into small portions of the workpiece as required. It is also known as a grinder. The grinding process is capable of producing very accurate sizes, equally accurate geometry like flatness or circle and extremely good surface finish.
