Simulation and optimization of a two-stage ball

01-07-2016  The breakage parameters obtained from wet grinding tests were scaled-up and then applied to simulate an industrial two-stage ball milling circuit. The simulation reproduced the size distributions of all streams, and the mill production rate with great accuracy. The simulation revealed that the mill operation was far below the optimum.

AMIT 135: Lesson 7 Ball Mills Circuits – Mining

Ball Mill Operation. Ball mills ride on steel tires or supported on both ends by trunnions. Girth gears bolted to the shell drive the mill through a pinion shaft from a prime mover drive. The prime movers are usually synchronized motors. During rotation, a portion of the charge is lifted along the inside perimeter.

Using modelling and simulation for the design

01-12-1997  This is in contrast to autogenous (ag) and semi-autogenous (sag) mill circuits where simulation techniques are now used as standard in most design projects. Undoubtedly the limited inroads that simulation has made in ball mill circuit design is due to the historic success of Bond's method [1] in crusher-ball mill and rod mill- ball mill circuits.

Grinding Circuit Simulation

These programs and the simulation algorithms are discussed below. Note that in some Grinding Circuit Simulations, a residence time distribution model is used. In the MRRC simulation package, however, only the two extremes of well mixed and plug flow through the mill are considered.
