Jacking/Lifting Cradle The mine is closed and now you need to know how to put the SAG or Large Ball Mill in care and maintenance does not have to be complicated to the point where you need bridge erection equipment for lifting a Mill (AG/SAG/Rod/Ball). You actually need
Maintenance-related events such as insurance and warranty inspections, alignment checks, lubrication system troubleshooting and many service and repair tasks require a clean gear set. When a large, conventionally geared SAG mill is involved, cleaning can require several hours of messy, mostly manual labor during a crucial period of mill downtime.

· Similar to the impeller design affecting pump capacity, the pulp lifter design affects the discharge capacity (or mill throughput) of AG and SAG grinding mills. Generally, the discharge from AG/SAG mills consists of one or both of the following components: slurry (water and finer particles) and pebbles (20-100 mm).

SAG Mill Circuit Example — Gold Processing SAG mill circuit example for gold processing [image: (135-6-3)] AG/SAG Mill. AG/SAG mills are normally used to grind run-off-mine ore or primary crusher product. Wet grinding in an AG/SAG mill is accomplished in a slurry of 50 to 80 percent solids. 2D and 3D simulations of particles in a SAG Mill

A successful mill shutdown can be measured by timely completion and zero harm. Removal and change out of worn liners and lifters as well as essential maintenance on existing mill lining is a job for a skilled professional team. “It is well known that using a mill relining provider can save up to 40% of downtime for scheduled mill reline works.”
Our vertical roller mills, horizontal mills, hydraulic roller presses and stirred mills have for many years offered efficient milling and grinding, flexibility, cost savings and easier maintenance. Whatever the application, one of our robust milling and grinding solutions will be suitable for grinding all types of feed materials including hard .

The final team, which left site today at 3pm EST has been the talk of the maintenance supervisors, their initiative to replace the liners on our SAG mill feed chute was appreciated beyond words. David Hewitt–Metallurgist , Raglan Mine. Graeme, I couldn’t ask for a better crew.
· Once the SAG mill is completed, the company expects underground production to sustain continuous milling. "We are very pleased with the progress we have made at Martha Underground where we have achieved first gold production and expect steady-state in the second half of the year," said Michael Holmes, president and chief executive.
