Abstract
At present, the removal of the bolts which fasten the liners should be carried out manually as part of the maintenance procedure SAG mills should be subjected to. The disadvantage of this procedure is the fact it should be carried out manually which makes the system to lose efficiency due to the high maintenance periods. Due to the above, a robot system and method have been developed to carry out this task automatically, in order to automate the removal of bolts from SAG and/or ball mills and thus to decrease the time used for maintenance. The robotic system is composed mainly of a robotic manipulator of at least 5 degrees of freedom, and a gripping mechanism which allows, in a sequential and programmed way, to take, manipulate and release a number of fastening bolts from the SAG mill, which are moved through a defined path to a bolt receptacle.
