Does A Grate Discharge Mill

 · Millar Western made a name for itself when it decided to make Meadow Lake a zeroliquideffluentdischarge mill. Working with the consultants at NLK, it designed an evaporation system to clean the water for reuse. The mill uses about 10% of the fresh water that a traditional mill of this type would use and only about % of the water a kraft mill would use. Meadow Lake takes a portion of the ...

To determine the power that a dry grinding needs, full grate discharge mill Equation 1 is multiplied by the factor of A multicompartment ball mill consists of two or more grate discharge ball mills in series. The same equation is used to calculate the power that each ball mill compartment should draw. The total power is the sum of the power calculated for each of the separate ...

In simple words, grate discharge mills give higher tonnage, but produce coarser grinding, that may cause problem in your Flotation recovery, Grate discharge will also reduce your EGL. The best option would be to place a retainer ring at discharge end to hold more charge that will give you more throughputs without compromising grind size.

The discharge voltage curve depends entirely on the discharge current. At constant current, the voltage curve is nonlinear and looks much like a standard capacitor. EXCEPT that there is an initial linear voltage drop that is due to internal and purely ohmic resistance. That voltage drop is also seen as an immediate voltage rise when the device is in constant current charge mode. In general ...
