A General Model for Semi autogenous and Autogenous Milling. an 8 m diameter SAG mill with LID = 0.5 grinding a copper ore, and predicted maximum ... performance of a typical SAG mill design ..... for small particle sizes.
Bond's first developments for grinding ores and rocks are now known as the Bond rod milling and ball milling grindability tests. The grindability results from these tests are still reported as "net grams produced per revolution of the test mill." Bond carried out two studies using his grindability tests:

Optimal control of grinding mill circuit using model predictive static programming: A new nonlinear MPC paradigm, MPSP is an innovative optimal control technique that combines the philosophies of model predictive control (.
Prediction of continuous steady-state ball milling using the traditional population balance model requires knowledge of several functions, namely those describing the rate and distribution of breakage products, the mass transfer relationship between the mill hold-up and the discharge, the mode of transport within the mill, as well as the description of internal classification, whenever present.
The model was based on three different industrial grinding operations including traditional multi-staged crushing followed by ball milling, traditional multi-staged crushing followed by rod milling and ball milling, as well as SAG and ball milling circuit configuration.
the mill is used primarily to lift the load (medium and charge). Additional power is required to keep the mill rotating. 8.1.3 Power drawn by ball, semi-autogenous and autogenous mills A simplified picture of the mill load is shown in Figure 8.3 Ad this can be used to establish the essential features of a model for mill …
An analytical solution for the dynamic model of tumbling mills is developed. The Direct Multiple Time method (DMT) algorithm is used to obtain analytical solutions. The analytical solution method is more accurate than the traditional numerical method.
AVEKA CCE Technologies also offers a lab-scale jet mill. The Model 20 Opposed-Jet Lab Pulverizer is designed to be used in closed circuit with the Model 100 Classifier (link to Air Classification) for the production of dry powders, in lab size quantities, at rates up to 4.5 kg/hr.
