As an integral part of a modern roll maintenance program, roll grinding and balancing uses machinery with accurate inspection and measurement equipment. This paper provides practical tips on roll inspections, balancing, grinding and grooving.
Calculate the surface speed of a wheel given its RPM and radius. The radius is 1/2 the diameter of the wheel. The RPM (revolutions per minute) is of the wheel, not the engine. Change units to that of the radius. ie foot, meter, inch, etc.
2.1 Calculation Of Wheel Speed And Feed To Grind Components It is important that the grinding wheel is not run beyond the maximum speed limit to that recommended by the manufacturer. Running the grinding wheel past the maximum speed limit could cause the wheel to disintegrate leading to serious injury.
The wheel speed, in terms of peripheral speed, is commonly in the range of 5,500 to 6,500 fpm (about 30 to 35 m/sec). High-speed grinding, operating at about twice that speed, is used on specially built surface grinding machines
mills especially not to briquetting rollers. There exist three models that are regarded as best suited for rolling compaction of powder: Johanson model [6-8], Slab method [8-11], and Finite Element Analysis (FEA) [8,12].
