### A = 69.3, b = 0.54 and Axb = 37.4 (Wtd Fit)

To use the Bond ball mill work index to determine the ball mill specific energy required for a particular grinding task, the Bond equation must be used and the various relevant efficiency factors applied.

### Mill (grinding)

F 80 is the mill circuit feed size in micrometers. Rod mill. A rotating drum causes friction and attrition between steel rods and ore particles. [citation needed] But note that the term 'rod mill' is also used as a synonym for a slitting mill, which makes rods of iron or other metal. Rod mills are less common than ball mills for grinding minerals.

### Grinding Circuit Design for Adanac Moly sgs

design of a plant for Adanac Moly Corp. to include SAG and Ball milling. The hardness of each sample was measured in terms of SAG power index, SPI (for SAG grinding) and Bond Ball mill work index, BWi (for ball mill grinding). A further measure, the Minnovex crusher index, Ci was also measured for use in the CEET program to determine SAG

### CALCULATION OF THE POWER DRAW OF DRY

To verify the new power draw approach, detailed surveys of the 14 ball mill circuits at 6 different plants were carried out. The ball mills sampled in this study are ranging in diameters from 3.2 m to 4.8 m. Design and operational parameters of the ball mills sampled are given in Table 1. Table 1.

### DESIGN OF THE KUBAKA GRINDNG CIRCUIT USING SPI

circuit, comprised of a 6.1 m diameter x 2.74 m long SAG mill and a 4.1 m diameter x 5.5 m long secondary ball mill in closed circuit with cyclones, was built using SAG Power Index and Bond Ball Mill Work Index testing to determine the grinding energy requirements.

### MODULE #5 FUNCTIONAL PERFOMANCE OF BALL MILLING

In a ball mill circuit, the "output" can be defined as the production rate of fines of the circuit. As for any output, ball mill circuit output is a function of both its inputs and efficiencies. There are two "inputs" to a ball mill circuit the ore fed to the circuit and the power delivered by the grinding mill.
