A study of the arrangements for pulp discharge on

arrangements on pebble mills, which has been, and still is, of particular interest to the principal author of this paper, has extended over many years. Commencing at the now defunct Geduld Proprietary Mines, where one of his first duties was the periodic clearing of blocked screen holes in the 1,7 m (5ft 6in) diameter secondary mills while

Dynamic Modeling and Simulation of SAG Mill Circuits

SAG mill and its pebble crushers. The scope of this thesis is to examine the dynamic relations between the SAG mill and the pebble crusher in a closed circuit and thus to optimize the circuit efficiency by controlling the pebble crusher operational settings. In this thesis, two modeling techniques are proposed for simulating the dynamics in the
