The same mill is used for the semi continuous grinding tests which is similar to the Bond test but with the exist- ing mill of known power. After time the mill product is t wet screened at a predetermined screen size. From the weight difference of the over size before and after grind- ing one calculates the grinding rate. The over size (cir-
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 ...

Jul 31, 2014· The following modified Bond equation was proposed for crushing (Magdalinovic, 1990): Wc = cP A Wi ( cP 10 - cF 10 ) (8) where: Wc - is energy consumed for clinker crushing (kWh/t), Wi - is Bond ball mill work index (kWh/t), Pc -is sieve size passing 80% of the clinker after crushing (µm), Fc - is sieve size passing 80% of the clinker before crushing (µm), A - is an empirical coefficient, …
Grinding energy- Crushing resistance 1- INTRODUCTION Comminution in a mineral processing plant, or mill, involves a sequence of crushi ng and grinding processes [1-2]. In order to design the comminuting process of a r ock, the required energy for crushing and grinding of the rocks must be calculated. This e nergy
