Difference Between Sag Mill vs Ball Mill - mech4study

SAG mill make use of steel balls included with some large and hard rocks for grinding. These mills utilize the balls in making the large fragments of materials broken into pieces. The ball charge of a SAG mill is about 9% to 20%.This process takes place inside the large rotating drum of SAG mill which is filled with balls partially.SAG Mill Grinding Circuit Design - 911metallurgist,23-09-2014· The most notable failures and difficulties in mill foundations have been caused by gear drives. Some examples we have worked on are: Mt Leyshon The three foundations at Mt Leyshon all failed within a short time. The failures were catastrophic, i.e., the cracks in the piers completely failed and there was no way that the mills could be operated.Trunnion Bearing Assembly Ball Mill & Rod Mill,The first part of the mill that we will look at is the TRUNNION BEARING. This is a HYDROSTATIC BEARING which is a slow moving bearing that carries a heavy load. Usually it is constructed from Babbitt’s metal. If you happen to remember the introduction to this course Issac Babbitt was the man who devised the method of bonding self-lubricating metals onto a strong backing to form a bearing,
