The high-strength centrifugal mill of above-mentioned books and periodicals report adopts the screening discharging, and the cone compass screen surface life-span end can't be guaranteed, and qualified powder can not in time be discharged and affected efficient.
Summary of the invention:
The present invention provides a kind of simple in structure in order to solve the deficiencies in the prior art part, and severity of grind is high, low energy consumption, the rational high intensity nodding centrifugal ball mill of selection by winnowing air-flow.
The technical scheme that the present invention takes is: a kind of nodding centrifugal ball mill: comprise base, power input pulley, main shaft, inclined hole axle sleeve, grind chamber, support and pneumatic separator up and down and form, power input pulley and the main shaft keyed jointing that stands, and to down and upward being installed on the base by lower bearing, thrust bearing, upper bearing (metal), bearing top keyed jointing inclined hole axle sleeve, but the topple crossed roller bearing of power of bearing radial force, axial force and side direction is housed on the inclined hole axle sleeve, is connected with lower mill chamber by upper and lower pressure ring.Median plane mounting spherical boss on the lower mill chamber, lower mill chamber is the annular housing of vertical section semicircle shape, lower mill chamber upper ring surface is furnished with two above radiation material toggling muscle, its periphery and smooth spherical outside surface (R
2) and smooth Internal Spherical Surface (R
1) upper mill chamber connect.On the base of bottom surface, lower mill chamber and correspondence upper and lower spacing ring is installed.The axial centre of crossed roller bearing and radial center are compiled in spindle centerline in " o " point, crossed roller bearing center line and spindle centerline form " α " inclination angle and are the swing inclination angle, grinding chamber is centered by " o ", when doing the nutating swing as the inclination angle take " α ", by lower mill chamber material toggling radiation tendon and lower mill chamber surface frictional force, oscillatory forces passes to the indoor medium of lower mill and material with energy, makes it to do high-strength centrifugal motion take nutating center " o " point as the average quality center.The medium of lower mill chamber and material then seamlessly transit the Internal Spherical Surface rotation by upper and lower mill chamber and rise, because the mill chamber cycle swings up and down and upper mill indoor spherical surface top openning is little, medium at a high speed can only be done to do the rotation descending motion after rotation rises to certain altitude, can not spill.
In order to be limited in the nutation movement, upper and lower mill chamber produces self rotation with creep speed, on the base of bottom surface, lower mill chamber and correspondence upper and lower spacing ring is installed, upper and lower spacing ring is the different cylinder ring gear of the number of teeth, on be limited to ring centered by " o " point owing to the reason that swings can only be rolled at the lower limit ring, and self do not rotate, effectively overcome the grinding chamber rotation of mill chamber with creep speed.
Described pneumatic separator forms the selection by winnowing shell by rack-mount selection by winnowing cylindrical shell, cushion rubber, conic tube, and the cushion rubber on the selection by winnowing cylindrical shell is vertical with main shaft, concentric, be slidingly connected at the outdoor sphere (R of upper mill
2) on.Mend the wind eddies ring, mend wind inner cone circle, mend wind outer cone circle, arranged tangential has the wind-supplying mouth more than 2 between selection by winnowing cylindrical shell and benefit wind outer cone circle, reach feed pipe, hopper, selection by winnowing impeller, impeller shaft, selection by winnowing motor, impeller belt pulley composition, enter the air of mending wind inner cone circle and mending wind outer cone circle by wind-supplying mouth and be the whirlwind shape and enter the mill chamber by the ring-type outlet of mending the inside and outside cone circle of wind by mending the wind eddies ring, along lower mill chamber, upper mill indoor spherical surface, selection by winnowing cylindrical shell, conic tube discharge from induced duct through the selection by winnowing impeller, is finished product through capturing.
The employing such scheme reaches beneficial effect and is:
1. main shaft is by the power-take-off pulley High Rotation Speed, the mill chamber is then by the effect of the crossed roller bearing on the inclined hole axle sleeve, upper and lower spacing ring, makes the main shaft high speed rotary motion become grinding chamber " α " centered by " o " point and moves for the high speed swinging that pivots do not done at inclination angle.Thereby eliminated the restriction of traditional ball tube mill critical speed.Kinetic energy is passed to medium ball and material makes it make the high speed three-dimensional centrifugal motion with the lower mill chamber of radiation material toggling muscle.The medium power conversion of unit volume or weight can reach more than 10 times of traditional ball tube mill.
2. on pneumatic separator, by mending wind inner cone circle and mend wind outer cone circle and air-makeup system that tangential wind-supplying mouth forms, the air draft passage that forms with selection by winnowing cylindrical shell, conic tube each other independently.Because benefit wind is to blow out from the ring-type outlet high speed vortex of mending the inside and outside cone circle of wind, forms the zone of silence that is similar to " typhoon eye " in benefit wind inner cone circle, feed pipe and hopper do not need special feed arrangement just can replenish material and medium in it.The qualified material that benefit wind is taken away from bottom, mill chamber is discharged by induced duct through the selection by winnowing impeller, and underproof larger particle has impeller blade to lay, and falls into smoothly in the benefit wind inner cone circle reverse taper, then falls into the mill chamber and continues grinding.
Cushion rubber on the cylindrical under the selection by winnowing cylindrical shell on the support, seat is on mill chamber smooth sphere centered by " o ".Sphere centre is motionless during owing to the work of upper mill chamber, as the horizontal cushion rubber on the outdoor spherical of mill and the cylindrical shell, forms slidably all the time rather than fixed enveloping surface, makes it to form good sealing gland between pneumatic separator and mill chamber.
3. medium of the present invention is made the high speed three-dimensional centrifugal motion, make the medium of same weight or volume obtain larger kinetic energy, thereby sphere diameter reduces, number increases, the grinding probability increases, more traditional ball tube mill, and appearance and size reduces 2/3, gross weight of equipment amount (containing medium) alleviates 3/5, and system energy consumption reduces more than 30%.The reagency that upper and lower mill chamber and abrasive media and material produce passes to ground by base, need not separately counterweight, the especially applicable ultra-fine grinding of the present invention.
