The Bond work index of limestone and andesite mixtures. This paper investigates grinding of mineral mixtures with different grindabilities in the Bond ball mill. Understanding the ore mixture grinding is of great importance in mineral processing. The energy required for crushing and grinding is presented by the Bond work index and is determined ...EXPERIMENTAL WORK Experiments carried out on samples of copper ore, andesite and limestone determined the value of Wi in a laboratory Bond ball mill with different aper- tures of test screen. Table I shows the values of Wi with the corresponding numerical values for Pk, P, F and G. Fig. 1 shows the relation G=f(~-~k) using the data from Table I.

This Grindability Test or Bond Ball Mill Work Index Procedure is used to determine the Bond Work Index of minus six mesh or finer feed ore samples. These equation application methods are used to process <1/2″ ore samples in a Ball Mill using a standard ball charge.. Below describes in general terms the Bond Work Index Procedure used by a Professional Metallurgical …Int. J. Miner. Process., 27: 125-132. The grindability of an ore in the process of mineral dressing can be determined by use of the Bond work index (Wi). This index is determined on a laboratory-scale using a Bond ball-mill and by simulating dry grinding in a closed circuit until the 250% circulating load has been obtained.

The Bond rod mill work index is not as common as the Bond ball mill work index, and there are two different variations on the mill apparatus.The SAGMILLING models expect a mill with a "wave liner", and is not compatible with mills using "smooth liners".According to the Bond standard procedure, the work index is determined by simulating a dry grinding in a closed circuit in the Bond ball ...micrometers in size. According to the Bond standard procedure, the work index is determined by simulating a dry grinding in a closed circuit in the Bond ball mill to achieve 250% circulating load (Bond, 1949, 1952, 1961). The test is performed on a raw material approximately weighing 10 kg, which coarseness is -3.327 mm.
