Mass balance - Wikipedia
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.
AMIT 135: Lesson 2 Circuit Mass Balancing – Mining Mill ...
Given the mass and component balance equations : F = C + R. Ff = Cc + Rr. Mass yield (Y) can be solved as a function of the stream, assays which yields the two-product formula: R = F- C. Ff = Cc + r (F – C) Mass Yield Formula Example
Grinding control strategy on the conventional milling ...
Crusher product (-9 mm) is fed to the rod mill, and the water is fed in ratio to the ore feed mass. The rod mill discharge is pumped, without any further water addition, to the first ball mill. The ball mill discharges to a sump where water is added before the slurry is pumped to the first cyclone (Cylcone 1).
Use of an Energy Balance around the Mill Sump to Estimate ...
