Jan 01, 1989#0183;#32;INTRODUCTION The energy consumption for grinding, according to Bond (1961), is deter mined by the formula: / 10 10 (I) The work index is determined by grinding experiments carried out in a labo ratory Bond ball mill. Based on the results of grinding experiments, numerical values of the work index Wi are calculated according to the formula: /89/ 1989 Elsevier Science

Cleaning and Storing of Ball Mill Charge after the Bond Work Index Procedure is done Add about 500 g of silica sand into the mill containing the ball charge Seal the mill Rotate for 20 revolutions to clean Empty the mill charge and sand into the ball try once grinding is complete Clean out the mill using a brush Put the lid on the mill.
Bond Ball Work Index Test A grinding mill (F305 mm 305 mm) was used for the Bond ball mill work index test [1821]. This ball mill was lled with 285 steel balls (total weight of kg) at an operation speed of 70 rpm. The feed sample was prepared via crushing and sieving, giving rise to a size smaller than mm.
