## A specific energybased ball mill model: From batch

Feb 01, 2016· 1 Introduction A specific energybased size reduction model for batch grinding ball mills has been developed (Shi and Xie, 2015)The objective of this work was to overcome the limitations in the existing JKMRC (Julius Kruttschnitt Mineral Research Centre) perfect mixing ball mill model, including the use of a set of default breakage appearance functions for allFeb 13, 2017· Here this Ball Mill Design Calculator Where the finished product does not have to be uniform, In this equation, E is the specific energy required for the grind, and F80 and P80 are the sizes in micrometers that 80% of the weight passes of the mill feed and product respectively The parameter Wi, known as the work index of the ore, isBall Mills Mineral Processing & Metallurgy

The energy specific cumulative grinding rate at each screen size is calculated from a torquemill test as in the example that follows Torque mill solids load during test: 1125 kg (248 lb) of ball mill feed sample from plant survey Sample is reconstituted with water to be the same percent solids as the plant ball mill discharge2 MODELLING THE SPECIFIC GRINDING ENERGY AND BALLMILL SCALEUP Ballmill scale up (Bond’s Law)Data: zBond work index w i zFeed D f and product d size (both 80% cumulative passing) Result: The specific grinding energy w Mill power draw P = wT, where T the mill capacity Mill dimensions (from Tables or charts)MODELING THE SPECIFIC GRINDING ENERGY AND BALLMILL

For overflow ball mills, the charge should not exceed 45% of the mill volume For grate discharge mills, the charge should occupy about 50% of the mill volume Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge, He, and the radius of the mill, R, ie,Semiautogenous (SAG), rod and ball mills As well as the total specific energy it will also predict the specific energy of the crushing section, the HPGR section and the tumbling mill section separately Hence, for example, in the case ofSPECIFIC COMMINUTION ENERGY SMC Testing
