Advanced comminution modelling: Part 1 – Crushers☆
Fig. 2 b shows a large gyratory crusher processing run of mine ore to 100–150 mm followed by two stages of cone crushing to generate a P80 of 6–12 mm which could be fed into a large ball mill operating in closed circuit with hydrocyclones. By using multiple process lines, these circuits could process up to 100,000 tonnes of ore per day.

Screening 101
By "closed circuit" crushing or grinding it is meant that the product from a crusher or grinder is fed to a screen. The material that has been reduced to sufficient fineness passes through the openings and the oversize is returned to the breaker for further reduction. Escape from the circuit can only be through the screen so this product ...
