Specification of grinding wheel: Grinding wheel is the main component of the grinding machine. It is responsible for the whole machining process. The proper selection of grinding wheel is very important and the selection of the grinding wheel depends on various factors such as a material of the work piece, finishing requirements etc.
typically stated in percents within a time period. A typical overload specification is by the VFD is 150% for 60 seconds, 1 per hour. 150% represents 1.5 times the motor's full load amp (FLA) rating, which equates closely to 150% FLT. In the case of grinding mills, kiln or crusher applications, the overload requirements can be 180%, 200%

The mill is set – via the direct three-phase drive and the exciter units – into inhomogeneous vibrations, which lead to the already mentioned high energy utilisation. The mill is filled with feed material via a nozzle at the highest point of the grinding vessel and the output at the lowest point at the other end of the grinding vessel.
Full Load Amp Rating. The FLA rating is the rate at which a motor will consume power at of rated load and at rated and balanced voltage. This number is extremely important, especially when dealing with electrical components. The wiring, starter, circuit breaker, and thermal overloads are all sized based upon the full load amp rating.
