The course of work of the present utility model is:

When ball mill starting with full load and normal operation, the hydraulic oil of hydraulic power unit is pressed into 10 of two axle journals 302 of quill shaft and two bearing bodies through a plurality of oilholes of main oil pocket 102 and auxiliary oil pocket 103, revolving body 3 is floated, form complete lubricating oil film, the power of power train 8 and motion drive gear wheel 31 through pinion 7, revolving body 3 is rotated, quill shaft 301 rotations are moved the hydraulic oil that is adsorbed on axle journal 302 external cylindrical surfaces thereupon, make the lubricating oil film attenuate of axle journal 302 screw-in bearing bodies 10 1 sides of quill shaft 301, even it is imperfect lubricating oil film to occur, two oilholes of the at this moment low pressure oil of hydraulic power unit 104 series connection through the repairing chamber flow out, guarantee that lubricating oil film is complete, realize that fully liquid is lubricated;

Treat the ore grinding material by certain filling rate from the right-hand member charging aperture, leading rib 304 through quill shaft 301 interior multi-head spirals is pushed in the cylindrical shell 32, mix with abrasive media, the centrifugal action of cylindrical shell 32 rotations and the effect of entrusting of corrugated liner plate 33, make the mixture sphenoid of cylindrical shell 32 interior formation mill Jie and mineral aggregate, let out under the mixture under Action of Gravity Field in the sphenoid, mill is situated between and mineral aggregate, the mill stripping occurs between mineral aggregate and mineral aggregate, the part mill is situated between and turns to oblique throwing of a certain height generation with cylindrical shell 32, oblique rubbing down Jie who has than high mechanical energy strikes in the mineral aggregate, the part mineral aggregate is smashed, entrust with the relative curve lifting rib 332 of peak valley in the cylindrical shell of cylindrical shell 32 rotations, near the mixture in two sides, curve lifting rib 332 protruding peak is alternately slided, not only liner plate and mineral aggregate, mill stripping effect between mineral aggregate and mineral aggregate strengthens, and make in the quick heavy mixture sphenoid of invading of lip-deep mill Jie of mill Jie and the mixture sphenoid of mineral aggregate, mill in the mixture sphenoid is situated between, heavy invading to the inner surface of corrugated liner plate 33 effectively avoids mill Jie who throws to clash into lip-deep mill Jie of mixture sphenoid fast; Mineral aggregate is after bump and mill stripping reach required particle diameter for several times, and mineral aggregate is led rib 304 through the spiral of left end quill shaft 301 and discharged;

During ball mill full-load run, because revolving body 3 deadweights, mill is situated between and the deadweight of mineral aggregate mixture and the effect of centrifugal force, when revolving body will produce less elasticity of flexure distortion, the rotational angle of bearing body 10 can be by rotary spacing plate 14 by 18 controls of bulb nut, unscrew bulb nut 18 rotary spacing plates 14 and can turn a low-angle by relative the second bearing pin 16, the hard-over of bearing body 10 is by fixedly limiting plate 112 restrictions of rotary spacing plate 14 hard-overs, two bearing bodies 10 just can be in the angle of rotary spacing plate 14 restrictions relatively rotate a smaller angle around the first bearing pin 15 separately respectively, make oil film thickness substantially constant vertically, can guarantee that lubricating oil film is complete, realize that fully liquid is lubricated;

Ball mill is fully loaded when static, because the width of main oil pocket 102 is less than quill shaft 301 axle journals 302 and bearing body 10 contact resilients distortion width, by the three row oil circuit in parallel with back pressure function, form main oil pocket 102 enclosure spaces, the hydraulic oil that its internal pressure raises and the weight of bearing body 10 structure shared revolving bodies and mixture;

The two pairs of opposite opened sleeves 40 that are fixed on the quill shaft 301 rotate synchronously with quill shaft, and opposite opened sleeve 40 and the labyrinth seal gap that seal closure 4 forms can prevent efficiently that dust granules from entering in the hydrostatic bearing seal closure;

Under the respectively effect of dextrorotation torsion spring 52 and left-handed torsion spring 62, rocker arm shaft 50 in the first local deduster 5 and the second local deduster 6, separately round brush 53 is pressed on respectively near opposite opened sleeve 40 external cylindrical surfaces the labyrinth seal structure 44 that the opposite opened sleeve 40 that rotates with quill shaft and seal closure 4 form, frictional force is rolled two round brush 53 fast, laying dust on opposite opened sleeve 40 external cylindrical surfaces that will rotate with quill shaft brushes off, and by round brush 53 lip-deep bull right hand helix grooves 531 and the left-handed helicla flute 631 of bull on the first local deduster 5 and the second local deduster 6, with the dust granule whiz labyrinth seal structure 44 of brushing in its groove, make near the laying dust Ex-all the labyrinth seal structure 44, greatly reduce the dust source that may enter by the labyrinth seal gap seal closure 4, realize that hydrostatic bearing is at dustless Space-Work.
