Sag Mill Foundation Design criteria

Grinding Mill Foundations

Sep 23, 2014 · This means that SAG mill foundations behave very differently from ball mill foundations. 4 – Mill Designer Stiffness Criteria One of the mill designers performs a calculation to determine the “target stiffness” of the foundations given the mill and ring motor stiffnesses. We have noticed that this ends up at about 10 MN/mm for large drives.

Manual design of SAG/ball/rod mill foundations ...

Mar 14, 2007 · As an engineer who has experience using FEM for the design and assessment of SAG and ball mill foundations, I know that this approach can be time-consuming, costly and -- in some cases -- not even a hope of being accurate if you don't have appropriate geotechnical and manufacturer information.


SAG/AG milling option is ideal for starter projects with significant exploration and expansion potential. Currently a number of the largest SAG mills designed are installed in single stage configuration. This paper discusses the challenges associated with the process design of single stage SAG/AG milling circuits, the design flexibility required to

operating SAG mills (it is not intended for design, but could help with it). Even if the mill total load is a key variable and can be indi-rectly measured with bearing pressure measurements, it was decided to discard it as an input variable. The main reason is that

Crushing Plant Design and Layout Considerations

As it turned out, designers are now adding secondary or pebble crushers to SAG circuits, on both greenfield and retrofit projects, to increase feed rate to the SAG mill. In other words, crushing plants, from primary to quaternary circuits, are here to stay. There are three main steps in designing a good crushing plant: process design, equipment
