Multicomponent AG/SAG mill model ScienceDirect
2013年4月1日 1 Introduction The Runofmine composition strongly affects autogenous mill operation However, the effects of a varying ratio of hard and soft components in mill performance are not described by the current generation of AG/SAG models (Stange, 1996)For example, current JKSimMet models (NapierMunn et al, 1996) assume a uniform feed, and describe it calculated with the aim of separately evaluating the model estimates to daily grade control estimates and to process headgrade estimates The following information is required to successfully compute these factors [10]: tonnes, grades and metal content of the longterm (block) model, shortterm model, grade control model, and also tonnes,Ore Grade Reconciliation Techniques – A Review Mining 2013年4月1日 The grinding media of autogenous mills derive from the feed ore size and composition (Delboni and Morrell, 1996) and the varying ratio of different components in the mill feed affects the mill charge and consequently the whole breakage process after developing a new AG/SAG mill model that describes the influence of mill charge composition on breakage Multicomponent AG/SAG mill model ScienceDirectHere are some common models of gold ore ball mills: 1 Wet Overflow Ball Mill: This mill incorporates a steel drum with a layer of grinding media (steel balls or ceramic balls) inside The drum is filled with gold ore and water, and the rotation of the drum causes the grinding media to tumble and grind the ore particlesWhat are the models of gold ore ball mills?
