Simulation and Optimisation of Crushing and Grinding Circuits

Course Objectives

• Analyse industrial plant data
• Review the JKMRC comminution and classification models
• Review ore characterisation using the JK Breakage Tests
• Learn and practise the concepts of mass balancing
• Learn and practise the concepts of model-fitting multiple data sets
• Simulate and optimise grinding (AG/SAG and ball mills) and classification circuits
• Simulate and optimise crushing and screening circuits.

Course Outline
This course provides training for those who wish to model, simulate and optimise crushing and grinding circuits. It will cover each of the models and demonstrate the model fitting procedure. The topics covered will include:

• Overview of comminution modelling at the JKMRC
• Hydrocyclone modelling
• Ball mill modelling
• AG/SAG mill modelling
• Crusher and screen modelling
• Mass balancing and model-fitting data
• Data sampling and collection techniques

Attendees are encouraged to bring some survey data with them for analysis with JKSimMet. This course will have a heavy emphasis on 'hands-on' work and one computer will be available for each two attendees. The first day of this course is the "Introduction to Data Analysis and Simulation" course.

This course is suitable for metallurgists and engineers who wish to learn the principles of applying simulation to the design and optimisation of grinding and crushing circuits.

All attendees receive Course Notes, a copy of the JKSimMet Manual and a copy of the JKMRC Monograph "Mineral Comminution Circuits".
