Advanced Simulation for Semi Autogenous Mill S ystems A Simplified Models Approach 147 description it is necessary to consider the relationship between the feed stream and mill charge level. This relationship is known as the transport rate and is probably the least developed aspect in models proposed so far (Apelt et al., 2002 a,b).

INVESTIGATION OF SORTING TECHNOLOGY TO REMOVE HARD PEBBLES FROM AN AUTOGENOUS MILLING CIRCUIT ABSTRACT Palabora Mining Copper has a unique ore body composition which unlike other copper ore bodies has three main components in significant proportions; these are copper bearing ore, magnetite and dolerite.
Autogenous and Semi Autogenous Mills Abstract The Julius Kruttschnitt Mineral Research Centre (JKMRC) has been involved in the study and modelling of industrial autogenous (AG) and semi autogenous (SAG) mills for over 25 years. Recent research at the JKMRC has developed a new AG/SAG mill model which is based on charge dynamics.
Mill length was the primary variable investigated in an autogenous pilot mill circuit. The 5 189; diameter mill had both pebble ports and 189; wide slotted grates. The plus 189; mill product was crushed in a cone crusher and returned to the mill feed along with the minus 189; plus 4 or 6 mesh fraction.
Investigation of sorting technology to remove hard pebbles from an Autogenous Milling Circuit. sorting technology was investigated at laboratory and pilot scale. It was found that a combination of optical and electromagnetic sorting could efficiently separate dolerite from the copper bearing and magnetite ores.
The reduction in mill load from 27.59 (pre TPL)to 14.46 (post TPL) includes the change due to elimination of both flow back and pebble pooling. The internal dimensions of TPL are designed using modelling and simulations to make sure all the particles that are passed IMPROVING AUTOGENOUS/SEMI AUTOGENOUS GRINDING PERFORMANCE AND
