Grinding wheels are sensitive to vibration due to their mass and speed. The faster your grinder, the more necessary it is to use balanced wheels. Unbalanced grinding wheels are NOT something you want on your grinder for several reasons: Inferior finishes on the tools that are being ground; Harm the bearings and bearing housings of the machine
A mass balance, also called a material balance, is an application of conservation of mass to the analysis of physical systems. By accounting for material entering and leaving a system, mass flows can be identified which might have been unknown, or difficult to measure without this technique. The exact conservation law used in the analysis of the system depends on the context of the problem ...
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. This paper provides practical tips on roll inspections, balancing, grinding and grooving.
employed to support the mass balances in the SAG lines1 and 2. • The mass balance results were consistent and coherent with the evolution of pulp density, particle size and solid flowrate in the secondary grinding circuits. • Low differences between the experimental and the adjusted data were
Under conditions where rotating speed is very high even though the mass is low, as in gas turbines or jet engines, or under conditions where rotating speed is low but the mass is high, as in ship propellers, balance of the rotating system should be highly considered, because it may generate large vibrations and cause failure of the whole system.
The "mass balance" is unquestionably the most common class of problems for the process engineer. Closely related, mathematically, is the "heat balance". Every laboratory test requires a mass balance to describe the results. Mass balance calculations can be subdivided into several sub-categories based on whether the results are time dependant or not and depending on whether the input ...

Some wheel adapters have provision for adding balance weights, or have weights that can be moved around a track. I had neither, so made an add-on to accept screws and washers as weights. Before continuing, I want to cover a few important safety items. Grinding is generally safe as long as wheel integrity isn't compromised.

Unbalance - The Common Cause of Vibration & Premature Bearing Destruction within Rotating Machinery Equipment. Unbalance is defined as an unequal distribution of mass causing the mass axis to differ from the bearing axis. During rotation, the unequal mass along with the radial acceleration due to rotation create a centrifugal force.
