Ball Mill and SAG Mill Shell Liner Design (3 replies)

I’m a designer working in a foundry casting mill liners where we have some designs for ball and SAG mils but we have design of other companies like Norcast, Outotec, FLSimdth all OEM's. We want to create our own design for liner for mill ball and SAG but we don't have knowledge for that. I need some information for design, relation between lifter and plates for example.

Granular Dynamics, International LLC (GDI) are experts in AG, SAG, and Ball Mill liner designs. We can typically enhance the design of mill liners to increase life, through-put, and lower KW-Hrs/Ton.

Please read the six papers from SAG 2001, 2006 and 2011 on our success. Metso Minerals use the basis of this technology. The new method includes rock breakage; wear mechanisms on liner surfaces, power consumption, and our ability to calibrate the model.

Normally, in sag mills there are three common types of liners namely: lifter bars, pocket and wave. These liners are used as per rock type (rock mechanics). One should understand the rock crystal analysis and materials with higher abrasive resistant to the rock. And the fracture mechanics of the material you are using to manufacture the liner. One must also understand the through put of particular mill mostly controlled by speeds; this may determine the type of liner you should use. Mostly, liners must be of manganese steels with 12%manganese added to 1%carbon steel and allowed to cool at room temperature, this makes the material structure to remain austenitic.

You might find these links interesting. These papers will take you through the basics.

I worked for many years in Minera Escondida (BHPBilliton), and this was one of my duties, where optimization and continues improvements were a real challenge because of the historic rivalry between maintenance and operations´ points of view.

What are you expecting to improve through your designs?
Do you know what mining customers are expecting really?

Have you expended some time on the mine site? I think this is the best way to understand and focus the right design, and taking into account that each mine site is different from another.
