[PDF] The Bond work index of limestone and andesite
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 for the Bond work index approximate value determination, which is based on the first order grinding kinetics, is presented in this paper Comparative experiments for the Bond work index value determination using the standard and quick procedures were carried out on samples of limestone andQUICK METHOD FOR BOND WORK INDEXAPPROXIMATE Probably the most accepted law was that of Bond, which tends by the well known Bond Work Index and can be expressed as: 10 Ni 10 Wi ferrosilicon, limestone, taconite and cement clinker Morebond work index of limestone equipment
