Mass Balance for Steady-State Grinding Circuit Model . It should be noted that the flow diagram representation of the process has been created by using so-called hierarchical blocks which allow placing a picture of choice on an existing library object (or a group of objects). For example, the SAG square is a hierarchy with the SAG mill set to ...

The dynamic process model of the grinding circuit consists of a phenomenological model based on the so called population balance concept (actually a mass balance) for the ball mill, an empirical model for the hydrocyclone classifier and a perfect mixing model for the sump.

Bond work index analysis takes this method of experimentation several steps further (Bond, 1952; Rowland, 1976). During comparative testwork, variations in the ore grindability, grinding energy input, and feed and product sizing are measured and accounted for through the grinding circuit "model embodied in the work index formulation.

The grinding circuit model was simulated at two raw-ore feed rates, 80 and 95 tph, for test purposes.The distribution of rod-mill feed size shows no change because it has been set constant and remains so unless altered by an exterior decision. The measured and predicted size distributions of the rod-mill discharges show a reasonable agreement.

Integration and Optimization of Blasting Crushing and . The survey sample sizing data were then used for mass balancing and calibration of crushing and grinding circuit steady state models Blast design changes were modelled and the predicted run of mine fragmentation 'fed' to the grinding circuit model during a number of simulations to achieve different increases in mill throughput

### Modeling the product net value of a grinding

Nov 04, 2010· Blast design changes were modelled and the predicted run-of-mine fragmentation 'fed' to the grinding circuit model during a number of simulations to achieve different increases in mill throughput. The blast patterns were designed to increase the amount of ultra fines generated during blasting that cannot be created through conventional ...
