limestone : andesite = 75 : 25. The Bond work index determination according to the standard Bond''s test is done on all these samples with comparative sieve size of 74, 105 and 150 microns. The Bond Work Index is calculated using the formula (Bond, 1961): ( ) (1) where: W i Bond work index (kWh/t); P c test sieve mesh size (#181;m);
The Bond work index is not solely a material constant but is influenced by the grinding conditions. For example, the finer the grind size desired, the higher is the kWh/t required to grind to that size. Magdalinovic [38] measured the Bond work index of three ore types using different test screen sizes. He produced a correlation between the mass of test screen undersize per revolution, G, and

Laporan Akhir Projek Penyelidikan Jangka Pendek Study of the The clinker samples collected also undergone standard Bond grindability test. The objective of the Bond ball mill test is to determine the socalled standard work index,.. carbonate found in calcareous rock such as lizenithne, silica, alumina,.
the different faces of quarry, Bond work index of limestone Face4A results less than 20kwh/t, remaining 6 samples are marked as hard rock because of high energy consumption and low grindability rate.
BOND WORK INDEX. The Bond Work Index is a factor that measures the energy consumed in size reduction operation of the ore. The Bond''s Work Index equation is: W=WI* (10/P80 10/F80) where. W= the energy input (Work input) per ton, kwh/metric ton. WI= Work Index= specific energy per ton, kwh/metric ton (characterizes the ore)
A bond index is a way of measuring the value of a portion of the bond market. the index fossils in the layer of limestone was dated to be about 115 million years old.
Among all seven samples collected from the different faces of quarry, Bond work index of limestone Face4A results less than 20kwh/t, remaining 6 samples are marked as hard rock because of high energy consumption and low grindability rate.

#0183;#32;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 by means of Bond grindability test. This paper presents the experimental results of the Bond work index
