This facility’s maintenance department adapted an automotive wench that allows repair crews to safely and effectively make repairs and perform maintenance in the crusher rotor area. The reduction in maintenance time has been significant, and the task is now safer for the repair crew. This wench device has enabled maintenance personnel to safely turn the rotors without tying themselves off or having to modify the guards in order to stop and spot the huge rotors for repair and maintenance. Repair personnel are now able to safely stand beside the crusher and move the rotors using a remote. This device allows a repair crew full view of the rotors with the lockout remaining intact, and has safely reduced the time to perform the required maintenance from more than two hours to just 30 minutes, while reducing the number of required personnel from three to one.

This facility struggled for many years when installing raw mill dams inside of a ball mill. The difficulty the workers faced was lifting the 400-lb dams inside of the mill with no means of hoisting from the inside of the mill. To improve the process, workers devised a lifting attachment that allows the use of a hoist located outside of the mill. The lifting attachment consists of a 5/16-in. wire rope that is connected to a threaded rod. The bolts used to fasten the dams to the mill shell are modified to accept the threaded rod by drilling and taping a hole on the threaded end. From outside the ball mill, the lifting attachment is threaded through a hex nut and then inserted through the hole in the mill shell used to fasten the dam to the shell. A modified bolt is put through a dam and connected to the lifting attachment, and then the dam is lifted into place. For just a couple hundred dollars of materials and labor, the lifting attachment has enabled the installation work to be performed more safely and more efficiently.
