Inquiry Online2.3 Ball Mill Model The main structure of the ball mill is composed of three parts namely the feed inlet the cylinder part work bin and the discharge port. Figure 2a shows the structural model of a ball mill. In the mill cylinder part there are lifters for turning over the particles. The quartz sand particles enter the cylinder through a
Analysis of ball mill grinding operation using mill . 2014-3-1 With a view to developing a sound basis for the design and scale-up of ball mills a large amount of data availe in the literature were analyzed for variation of the two key mill performance parameters: power specific values of the ‘absolute breakage rate of the coarsest size fraction’ S and ‘absolute rate of production ...
As a result mines have shifted their emphasis in optimization from ball mills to SAG mills. The rock load in the mill essentially depends on ore characteristics and the discharge rate of broken particles through the discharge end. The discharge rate depends on how efficiently the discharge pump grate and pulp lifters operates.
