The SAG mill specific energy consumption is deducted from the total circuit specific energy consumption to get the ball mill specific energy consumption: E bm =E total −E SAG (8) Determine Mill and Motor Size Knowing the SAG and ball mill specific energy consumption allows mill sizes to be calculated if a desired throughput rate is known.
SAG mill specific energy was a function of the inverse of the Axb value, the mill geometry and the mill operating conditions. Chat Now; Identifiion of Optimal Mill Operating Parameters during Grinding . ... comminution, breakage rate, ball filling, kinetic models, simulation. 1.
• Single stage crush/single stage SAG mills and two stage crush/ball mill circuits are typically selected for low throughput plants (<50 t/h) where personnel costs are a large component of costs. • SAB circuits are typically selected for plants of to 2 Mt/a.
Different impact levels and amounts of specific comminution energy can be obtained by varying the drop weight, the falling height or the fragment mass. ... that can be correlated to Axb and to the Bond ball mill work index (compare Section ), respectively. ... licensee MDPI, Basel, Switzerland. ...

ball mills in producing the final product (particles finer than 74 µm) was % and % respectively. That is, the SAG mill produces about % more than the ball mill in the final product. The average consumed energy at SAG and ball mills to produce one ton of final product was kWh/t and kWh/t respectively.
ticular F80 and P80) is a property of the rock and any difference in specific energy of different comminution devices is (largely) reflective of the efficiency of the grinding device. Once the specific energy is determined, the amount of grinding power needed (at the mill shell) is found by mul

Several energy efficient options for cement grinding are available today such as vertical roller mills, roller presses (typically in combination with a ball mill), and clinker pregrinders with ball mills. Ball mills have been the traditional method of comminution in the mineral processing industries and continue to operate with old generation classifiers, their maintenance sometimes neglected.
Despite this latter inability, this study shows that the establishment of the relationship between size modulus x f and breakpoint x b, as shown in Figures 9 and 10, enables the full definition of the relationship between energy input and particle size distribution of the milling products.

Advances in Comminution comes at a critical time. It focuses on the dilemma of needing to grind materials to everfiner sizes while maintaining reasonable energy costs. The selection and sizing of stirred mills for regrinding and ultrafine grinding applications do not lend themselves to conventional methodologies; therefore, new approaches are being developed.
