Optimisation of the ball charge in mills for cement grinding
The development of Loesche vertical roller mills for large capacity grinding is discussed With 3+3 technology, the company is prepared to replace 2 to 3 ball mills in cement grinding plants withTo get rid of pulp and rocks in the charge, a mill grindout (no ore feed) of 10 to 20 minutes is also performed before mill inspection or relining The complete grindout is required to obtain the accurate ball load measurement or the percentage by volume of balls in the mill This is usually performed soon after a crash stopOptimization of mill performance by using SciELO
