Mass balance in closed circuit grinding (4 replies and 2 comments)
Please join and login to participate and leave a comment.
How to establish a mass balance and derive the circulation load of a closed circuit given the specific gravities of the mill discharge to classifier, underflow and overflow from the classifier?
An iron ore company milled ore at the rate of 150 t/h in a ball mill in closed circuit with a classifier. The underflow (course) stream was recirculated to the mill till a steady value was obtained in the cyclone overflow stream. The specific gravities of each stream were measured as:
a) Mill discharge stream to classifier = SG(md)
b) Product overflow from the classifier = SG (of)
c) Product underflow from the classifier = SG (uf)
Establish a mass balance and derive an expression for the circulating load. (in terms of densities or specific gravities of the streams)
p.s I've been solving this problem for like 8 hours and I'm not sure if Jones' assumption is valid.
