Ball mill is a kind of equipment for grinding, mainly comprise rotor and stator, space between rotor and stator forms grinding chamber, material is sent in grinding chamber and is ground, the main grinding principle of ball mill be by be positioned at the grinding rod on rotor and stator and pour into grinding chamber steel ball realize, grinding rod when rotor rotates on rotor driven rotates, material is under the acting in conjunction of grinding rod and steel ball, in grinding chamber, produce and mix simultaneously, disperse, rub, roll, the effect of the physics such as friction and shearing, but the ball mill of prior art is mainly a rotor cylindrical shell and a stator column that is positioned at rotor cylindrical shell to be formed, material is incorporated between rotor cylinder inboard wall and stator column outer wall and grinds, therefore disposable amount of grinding is less, and efficiency is not high yet.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides a kind of ball mill, this ball mill has larger grinding cavity, and therefore amount of grinding is large and efficiency is high.
The present invention for the technical scheme that solves its technical problem and adopt is:
A kind of ball mill, comprise stator and rotor, between described stator and rotor, form and grind cavity, described stator and rotor are provided with some grinding rods, and some grinding rods are positioned at and grind cavity, described stator is stator cylindrical shell, described stator cylindrical shell is by circular bottom surface, cross section is that the outer ring barrel of annular and inner ring barrel that cross section is annular form, described outer ring barrel is upwards made of one piece by the edge of described bottom surface, described inner ring barrel is upwards made of one piece by middle part, described bottom surface, and described bottom surface, outer ring barrel and inner ring barrel concentric, described rotor is rotor cylindrical shell, described rotor cylindrical shell is by circular end face, cross section is the rotor barrel of annular, cross section is that circular newel and cross section is that circular connecting axle forms, described rotor barrel is made of one piece downwards by the edge of described end face, described newel is made of one piece downwards by the center of described end face, described connecting axle is upwards made of one piece by the center of described end face, and described end face, rotor barrel, newel and connecting axle concentric, rotor barrel is between described outer ring barrel and inner ring barrel, described newel is arranged in described inner ring barrel, the barrel upper end, outer ring of described stator cylindrical shell is fixed with end cap, stator cylindrical shell and described rotor cylindrical shell upper end described in described end cap seal, the connecting axle of described rotor cylindrical shell passes described end cap and is connected with the output shaft of motor, movable sealing between described end cap and described connecting axle, on described end cap, offer charging aperture, described charging aperture is connected with the grinding cavity between described outer ring barrel and rotor barrel, the bottom center of described stator cylindrical shell offers discharging opening, described discharging opening top is provided with screening plant.
Bottom surface, outer ring barrel and the inner ring barrel of described stator cylindrical shell and end face, rotor barrel and the newel of rotor cylindrical shell all have the interlayer of hollow, and in described interlayer, circulation has cooling water.
The invention has the beneficial effects as follows: ball mill of the present invention comprises by bottom surface, the stator cylindrical shell that outer ring barrel and inner ring barrel form and by end face, rotor barrel, the rotor cylindrical shell that newel and connecting axle form, rotor barrel is between outer ring barrel and inner ring barrel, newel is arranged in inner ring barrel, between outer ring barrel and rotor barrel, form outer ring and grind cavity, between rotor barrel and inner ring barrel, form centre circle and grind cavity, between inner ring barrel and newel, form inner ring and grind cavity, therefore the ball mill of invention has triple grinding cavitys, material grinds cavity through outer ring after being entered by charging aperture successively, centre circle is discharged by discharging opening after grinding cavity and the grinding of inner ring grinding cavity after screening plant screening, therefore, than tradition, only there is a ball mill that grinds cavity, amount of grinding of the present invention is larger, grinding efficiency is higher.
Accompanying drawing explanation
Fig. 1 is ball mill sectional structure schematic diagram of the present invention.
The specific embodiment
Embodiment: a kind of ball mill, comprise stator and rotor, between described stator and rotor, form and grind cavity, described stator and rotor are provided with some grinding rods, and some grinding rods are positioned at and grind cavity, described stator is stator cylindrical shell 1, described stator cylindrical shell is by circular bottom surface 11, cross section is that the outer ring barrel 12 of annular and inner ring barrel 13 that cross section is annular form, described outer ring barrel is upwards made of one piece by the edge of described bottom surface, described inner ring barrel is upwards made of one piece by middle part, described bottom surface, and described bottom surface, outer ring barrel and inner ring barrel concentric, described rotor is rotor cylindrical shell 2, described rotor cylindrical shell is by circular end face 21, cross section is the rotor barrel 22 of annular, cross section is that circular newel 23 and cross section is that circular connecting axle 24 forms, described rotor barrel is made of one piece downwards by the edge of described end face, described newel is made of one piece downwards by the center of described end face, described connecting axle is upwards made of one piece by the center of described end face, and described end face, rotor barrel, newel and connecting axle concentric, rotor barrel is between described outer ring barrel and inner ring barrel, described newel is arranged in described inner ring barrel, the barrel upper end, outer ring of described stator cylindrical shell is fixed with end cap 3, stator cylindrical shell and described rotor cylindrical shell upper end described in described end cap seal, the connecting axle of described rotor cylindrical shell passes described end cap and is connected with the output shaft of motor, movable sealing between described end cap and described connecting axle, on described end cap, offer charging aperture 4, described charging aperture is connected with the grinding cavity between described outer ring barrel and rotor barrel, the bottom center of described stator cylindrical shell offers discharging opening 5, described discharging opening top is provided with screening plant 6.
