SCREEN CAPACITY CALCULATION - VIBFEM

 · Current screen capacity calculations do not take into consideration enough of the factors affecting screen efficiency. The old formulas were designed to keep calculations short and manageable for manual calculation. The common use of computers in today's world makes it possible to do more complex screen capacity calculations in much shorter time.

First, a Jar Mill grindability test requires a 5 lb. (2 kg) sample and produces a direct measured specific energy (net Hp-hr/t) to grind from the design feed size to the required product size. The second test, a Bond Work Index determination, results in a specific energy value (net Hp-hr/t) from an empirical formula.

Nominal Capacity vs Actual Vs Actual Useable Capacity

Actual Useable Capacity . This is the available amount of water you can physically use in the tank before you start taking air into the system. It is calculated between two datum points; the top water level volume (see actual capacity) and a dimension at the bottom of the tank, which is either the top of the outlet or the low-level switch (pump protection).
