JK Drop Weight Test - SGS

JKSimMet autogenous mill modelling program. The JKTech drop weight test provides ore-specific parameters which are used by the JKSimMet Mineral Processing Simulator software to analyse and/ or predict AG/SAG mill performance. The same test procedure also provides ore-type characterisation for JKSimMet crusher modelling.The Selection and Design of Mill Liners - MillTrajMines (WA) 36ft SAG mill the number of Outer Head Liners was reduced from 36 to 18 pieces and in doing so reduced the time to replace them by 9 hours at a cost downtime saving of about U$25,000 per hour. In this case the liners sections are 3.5 t each.

A Method of C alculating Autogenous/ Semi-Autogenous ...

Rod mills are limited in size to 2000 kW because the longest commercial grinding rod available is 6 m long. For this reason rod mills are rarely selected in the present day environment of large AG/SAG mills and large ball mills. However, it is necessary to discuss their operation because a Rod mill product has a similar slope to AG/SAG mills.Mill (grinding) - WikipediaSAG is an acronym for semi-autogenous grinding. SAG mills are autogenous mills that also use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21%. The largest SAG mill is 42' (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor.
