Grinding Mill Foundations
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.

Ball Mill Maintenance & Installation Procedure
This is done by using a higher shim at the center than at the ends and tightening the foundation bolts of both ends. Ball Mill Sole Plate This crown should be between .002″ and . 003″, per foot of length of sole plate. For example, if the sole plate is about 8′ long, the crown should be between .016″ and .024″. Ball Mill Sole Plate
Calculation Of Sag Mill Weight From Bearing Pressures
Trunnion Bearing Assembly Ball Mill & Rod Mill. The oil that is on the surface of the bearing is forced into a wedge shaped portion of the leading edge of the outer bearing This will generate enough pressure to lift the entire mill But if the pump isn't kept pumping for that revolution the weight of the mill as' it turns will force the metal of the bearing surface into the oil channels.
SAG vs Ball Mills – COMESA
It's important to point out that in a SAG mill, the crushing load is composed of two components; the mineral rocks and the iron balls. Thus the mineral type affects SAG mills more than ball mills. Due to the heterogeneous nature of the foundations, the minerals don't …

What is the difference between a SAG mill and ball mill?
SAG is an acronym for semi-autogenous grinding. SAG mills are autogenous mills that also use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21%. [6] [7] The largest SAG mill is 42′ (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor. [8] A SAG mill with a 44 ...
