Problems

Optimisation of feeder operations

Delay of response in speed-weihgt control loop

Objective: reduce variability of the ore feed to the mill, increase circuit throughput

High feeders' speed variability

Difficulty in manually selecting optimal feeder speed

Reduction in average throughput

Application:
feeders speed control

Solution

Model corrects feeders' speed automatically based in model predictions

Model predicts ore weight 3 minutes in advance to correspond with real time operation of feeders

Application: feeder speed control

Adjustments every 7-10 seconds

Feeding dynamics of the mill with application
Maintaining the feed rate (t/h) of mill within required parameters

Results

-50%

Reduction in mill feeding variability

+0.7%

Increase in throughput
