Morrell Mi (SMC) SAG & ball mill Model. This is a SAG or AG mill plus ball mill model that estimates the specific energy consumption (E SAG) using the equations of Morrell (2004). Testwork Required. The SMC™ test, stored in the "DWT" testwork table (SMC is a Drop Weight Test). Bond ball mill work index.
S Morrell, YT Man. . ： Computer simulation of ball mill cicuits has been found to be very valuable for optimisation where existing plant data can be used to calibrate the mathematical models used. However, as by definition no existing plant is …
ball mills (Figure 2b)(Morrell, 1993, 1996a). However, from experience gained with single stage AG/SAG mills it became clear that even grate discharge mills can accumulate slurry at the toe of the charge and this can considerably affect power draw depending on the extent of
You also need a rod mill work index to design a ball mill operating on a coarse feed, above about 4 mm. Q1: You design for a typical percentage of critical speed, usually 75% of critical. Then you iterate the mill diameter using a Morrell C-model or equation to get the RPM that corresponds to 75% for that mill diameter.

Morrell SMC HPGR and Ball Mill Circuit model: Set the crusher product size to 35 000 µm and the transfer size to 3500 µm. Circuit feed size 150 000 µm and product size 75 µm (optional) Set the conveyor lift height to 30 m; Result is 745 t/h circuit throughput with E total of 20.5 kWh/t (excluding auxiliary equipment)
If you are going to use Morrell equations, then also calculate the Morrell specific energy for each ball mill test, E ball = 4 × Mib (P80 -0.295-P80×10^-6 - F80 -0.295-F80×10^-6 ). Fit the specific energy results for all BM tests, E ball = K × P 80-a.
Morrell single-stage ball mill Model. This is a secondary and tertiary cone crusher, plus ball mill model that estimates the specific energy consumption using the equations of Morrell (GMSG, 2016). The secondary crusher operates in open circuit and the …
Morrell method and equations. The Morrell method can be applied for the design and optimization of comminution circuits. The method essentially consists of two parts: • Part 1: Power draw modelling of equipment such as ball mills and autogenous grinding (AG) and semi-autogenous grinding (SAG) mills.

So for example it is generally recognised that a crush-HPGR-ball mill circuit is more energy efficient than, say, one comprising crush-sag mill-ball-mill (Morrell,2008 2). At the design stage, therefore, there is an oportunity to select the most energy efficient circuit.
Additional studies were conducted for adapting both industrial feed size distributions and ball top size to bench-scale tests, the latter included the procedures developed by Morrell and Man (1997) MORRELL, S., MAN, Y. T. Using modelling and …

Calculate the Bond specific energy of each ball mill test, E ball = 10 × Wi (P80 -0.5 - F80 -0.5 ). If you are going to use Morrell equations, then also calculate the Morrell specific energy for each ball mill test, E ball = 4 × Mib (P80 -0.295-P80×10^-6 - F80 -0.295-F80×10^-6 ). Fit the specific energy results for all BM tests, E ball = K ...
milling followed by ball milling), only the P80 of the product of the final milling stage is required. In addition to the above data, a representativesample of the primary crusher product is required for subsequent laboratory hardness characterization. 7.2 From the Laboratory The Morrell method uses hardness parameters obtained
Ball Mill Design. A survey of Australian processing plants revealed a maximum ball mill diameter of 5.24 meters and length of 8.84 meters (Morrell, 1996).
A Review of Advanced Ball Mill Modelling ... (Morrell, 2004). These different approaches have one thing in common: they use a single number to describe energy in grinding. This number, the specific energy, is the ratio between the power and the throughput in the case of continuous sys-
