Jul 19, 2018 Hydrostatic trunnion bearings were recently provided on large Semi-Autogenous Grinding (SAG) mills driven by wraparound motors assembled on the head to shell flanges. A conventional SAG mill would have a ring gear driven through one or two pinions.
Hydrostatic bearings are applied for demanding applications where conventional plain bearings and rolling bearings cannot meet the exacting demands of a grinding machine. However, hydrostatic bearing systems tend to be relatively expensive and will therefore be avoided if capital cost and machine simplicity are given priority.
The Polymer Hydrostatic Shoe Bearing (HSB) system significantly improves radial and axial bearing reliability and longevity. It maximizes grinding mill availability and simplifies maintenance, increasing revenue and reducing maintenance costs. Benefits Longer bearing-pad service life and easier maintenance Improved hydrostatic efficiency
Grinding Mill Head processing The mill generally uses hydrostatic bearings, and the journal is the main contact surface. The tolerance requirements of size, roughness and shape are very strict. The requirement of end and radial runout in the journal area is within 0.05 mm, and the surface roughness is less than 0.8 um.
Mill bearings The type of support bearing is selected on the basis of mill size, intended duty and environmental conditions at the installation site. Outotec offers mills supported on a variety of bearing arrangements hydrodynamic and hydrostatic journal, spherical roller, hydrodynamic and hydrostatic multi-pad bearings.
Jul 28, 2015 This is a HYDROSTATIC BEARING which is a slow moving bearing that carries a heavy load. Usually it is constructed from Babbitts 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.

In surface finishing of a grinding machine, the dimension accuracy of the workpiece is most affected by the stiffness of the spindle. For the hydrostatic spindle of a medium-sized circular grinding machine, the primary factors affecting the oil film stiffness are bearing structure parameters, lubrication characteristics, and working conditions.
(d) relatively high frictional losses in hydrostatic sleeve bearings, representing some 7 to 9 per cent of the mill horsepower supply. Item (d), the hydrostatic sleeve bearing, requires sustained high pressure to maintain lift and so retain the oil film. The power required to maintain the high pressure is about 4 per cent of the mill horsepower ...
