Working principle While working, motor drives the hanger of the grinding roller to rotate through V pulley and centre bearing. The roller, which is hung by bearing and pendulum shaft, will roll along the inner circle of the roll ring while the hanger is rotating.
· Consistent grinding and balancing of rolls is necessary for efficient operation and optimum paper quality. As an integral part of a modern roll maintenance program, roll grinding and balancing uses machinery with accurate inspection and measurement equipment.
Grinding is the most common type of material cutting and surface generation process. Mostly grinding process is used to shape and to provide better finishing parts of metals. Grinding process uses one abrasive tool to make controlled contact with workpiece surface. Normally grinding wheel is used as abrasive tool in process of grinding.
· High pressure grinding roll is a kind of advanced grinding equipment developed by Germany scientists in the 1980s. It was popularized soon in USA, German, Russian, Brazil, Chile, Australia and other advanced industrial counties because of simple structure, high production efficiency, environmental protection and energy-saving and advanced working principle.

A grinding wheel surface consists of abrasive grains that form the cutting edges, bond material to retain the grains in position, and surface pores that allow space for material removal from the work surface. The wheel surface is usually prepared by a truing or dressing operation.
· Introduction Grinding is a metal cutting operation performed by means of abrasive particles rigidly mounted on a rotating wheel. Each of the abrasive particles act as a single point cutting tool and grinding wheel acts as a multipoint cutting tool. The grinding operation is used to finish the workpieces with extremely high quality of surface finish and accuracy of shape and dimension. …
requires fewer particles to be in contact with the grinding medium, that is, the roll surface (Klymowsky, 2009). There is, however, a negative aspect of particle-bed grinding, namely a retardation effect. Grinding virtually comes to a halt in highly compressed beds at
