If the equations for Availability, Performance, and Quality are substituted in the above and reduced to their simplest terms the result is: OEE = (Good Count × Ideal Cycle Time) / Planned Production Time. This is the "simplest" OEE calculation described earlier. And, as described earlier, multiplying Good Count by Ideal Cycle Time results ...

voltage at electrical equipment will be less than the output voltage of the power supply. This will result in inductive loads (i.e. motors, ballasts, etc.) operating at voltages below its rating-which in turn can cause them to overheat — resulting in shorter equipment operating life and increased cost, as well as inconvenience for the consumer.

This equation reverts to the Bond equation (Equation ) by taking the value of B as 12 and integrating; thus, (3.7) E = k 1 P 6 12 − 1 F 6 12 which in effect is the Bond equation. Bond's original work on establishing the energy for size reduction was established in a 2.44 m (8 foot) internal diameter wet grinding overflow type ball mill.

Buffer capacity: Definition. Before we get into what a buffer capacity is, we should first understand buffers. A buffer is a compound that resists changes in pH when a limited amount of acid or base is added to it. The chemical composition of a buffer solution usually entails a weak acid or a weak base accompanied by its conjugate salt.
