cost for a gravity circuit is much lower than that for any other process. Minimizing the Size of the Gravity Concentration Circuit Many process engineers view gravity concentration in gold grinding circuits as a nuisance and a security risk. In part, this is probably due to the chequered history of enhanced gravity concentration, and the inability to predict the impact a gravity .

Development of size reduction equations for calculating ...

· Size reduction is an essential but energyintensive process for preparing biomass for conversion processes. Three wellknown scaling equations (Bond, Kick, and Rittinger) are used to estimate energy input for grinding minerals and food particles. Previous studies have shown that the Rittinger equation has the best fit to predict energy input for grinding cellulosic .
