More### Dynamic Modelling of Temperature in a Wet Ball Mill

2019-9-1 A dynamic model is developed for a wet overflow ball mill based on a set of mass and energy balances. The energy balance relies on temperature and mass flow data. The key model parameters to be measured are mill temperature in the feed and discharge streams, mill power draw and the mass flow rate in the feed stream.

More### Discrete Event Simulation of an Iron Ore Milling Process

2011-9-9 One of the first simulations of the ore processing plant was done by Ford and King (1984). De Andrade, Lima and Hodouin (2006) performed another simulation study, which falls into the second category. The authors of this paper simulate cyanide distribution in a gold leaching circuit. A simulation design which treats the processing plant as a whole and suggests an approach for measuring and managing variations in a mineral processing plant is proposed in Robinson (2003). Fourie (2007) also proposes a modeling approach for studying any metal separation circuit (flotation, magnetic separation or electrostatic separation). Delgadillo et al. (2008) integrate the grinding machines along with the classifiers and magnetic separators and simulate
