To liberate valuable minerals held within particles[2] 3 4. Introduction • Grinding and crushing usually account for more than 30 to 50% of the total power used in the concentration process, but this can rise as high as 70% for hard finely dispersed and intergrown ores.[1] but about 5 % of all electricity generated is used in size reduction[2] 4

Modelling and Simulation of Air ... - Scientific.Net

In cement manufacturing, the finish grinding circuit consumes more energy from the raw grinding circuit. Thus, it is necessary for the system to have an efficient air classifier in order to reduce the energy consumption of the cement production. A mathematical model was developed for describing the air classification in the air classifier, in the finish grinding circuit.
