The utility model discloses a ball mill inner lining structure. The ball mill inner lining structure comprises a ball mill barrel, wherein the inner wall of the ball mill barrel is provided with an inner lining structure built by a plurality of aluminum oxide lining bricks; and the surface of the inner lining structure is provided with a plurality of wave shaped inclined bosses along the axial direction of the ball mill barrel. According to the ball mill inner lining structure, the milling efficiency of the ball mill can be improved, the milling time of the ball mill can be shortened, the operation current of the ball mill can be reduced, and thus the energy-saving and consumption-reducing purposes are achieved.
Description
Technical field
The utility model relates to a kind of ball mill structure that is widely used in the industries such as pottery, cement, paint, pigment, chemical industry, medicine and coating, is specifically related to a kind of inner liner of bowl mill structure.
Background technology
Be widely used in the ball mill of the industries such as pottery, cement, paint, pigment, chemical industry, medicine and coating, liner need be set on its ball mill barrel inwall be worn with the protection cylindrical shell, and prevent that material from contacting, avoiding material pollution with iron.Existing ceramic industry inner liner of bowl mill mainly contains natural lining stone, rubber liner, middle high alumina lining stone and alumina lining brick.Natural stone lining is because composition is unstable, impurity is many, causes easily paste composition unstable, and abrasion are large, and service life is short.Rubber liner is easily sneaked into slurry because the low molten thing of organic principle is more, and is influential to pulp brightness, and easily causes pin hole, though wearability is good, to having ground cushioning effect, reduced grinding efficiency.Middle high alumina lining stone primary raw material is quality oxide aluminium, purity is high, wearability is good, and physical life is long, and well corrosion-resistant, high density, high mechanical properties are arranged, institute's defibrination material purity is high simultaneously, relatively finer and smoother, but because middle high alumina lining stone density is large, quality is heavy, make the ball mill starting current larger, energy consumption is larger.Although alumina lining brick is firm wear-resisting, but because existing alumina lining brick adopts substantially rectangular brick laying structure more, its brick body upper surface mostly is the plane, therefore builds the inner lining structure that forms by this kind structure alumina lining brick dress, its inner lining surface lacks concavo-convex variation, and its grinding efficiency has much room for improvement.
The utility model content
The purpose of this utility model is for the deficiencies in the prior art part, and a kind of simple in structure, inner liner of bowl mill structure that can the Effective Raise grinding efficiency is provided.
For achieving the above object, the utility model adopts following technical scheme:
A kind of inner liner of bowl mill structure comprises ball mill barrel, and the inwall of described ball mill barrel is provided with by some alumina lining brick dresses and builds the inner lining structure that forms; The surface of described inner lining structure is along some wave inclined platforms of axial formation of ball mill barrel.
As preferably, described some wave inclined platforms with substantially equidistantly mode be formed on the surface of described inner lining structure.
As preferably, be provided with the inclined platform section corresponding to the upper surface of each alumina lining brick of every wave inclined platform present position, described every wave inclined platform is continued from beginning to end by those inclined platform sections and forms.
As preferably, the transition arc of described every wave inclined platform and the radius of ballstone match.
As preferably, the cross section of described alumina lining brick is rectangular structure substantially.
As preferably, be respectively equipped with tongue-and-groove on the side elevation of described alumina lining brick, the opposite side facade that described alumina lining brick is relative with a described side elevation is provided with the tenon platform that closes with described tongue-and-groove tenon.
The utility model can improve the grinding efficiency of ball mill owing to adopt said structure, shortens the milling time of ball mill, lowers the work revolution electric current of ball mill, reaches energy-saving and cost-reducing purpose.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 a is the structural representation of the first alumina lining brick described in the utility model.
Fig. 2 b is the structural representation of the second alumina lining brick described in the utility model.
Fig. 2 c is the structural representation of the third alumina lining brick described in the utility model.
Fig. 2 d is the structural representation of the 4th kind of alumina lining brick described in the utility model.
Among the figure:
1-ball mill barrel; 2-inner lining structure; 21 wave inclined platforms; 22-low-lying district; 3-alumina lining brick; 31-inclined platform section; 32-tongue-and-groove; 33-tenon platform.
Now in conjunction with the accompanying drawings and embodiments the utility model is described in further detail.
The specific embodiment
As depicted in figs. 1 and 2, a kind of inner liner of bowl mill structure described in the utility model, be with some cross sections substantially rectangular structures and the two opposite sides facade alumina lining brick 3 that is respectively equipped with tongue-and-groove 32 and tenon platform 33 build the inner lining structure 2 that forms at the interior wall of ball mill barrel 1.On the surface of this inner lining structure 2 along ball mill barrel axially with substantially equidistantly mode form some wave inclined platforms 21, every wave inclined platform 21 is that inclined platform section 31 head and the tail by the upper surface setting of each alumina lining brick of inclined platform present position continue and form.Thus, the concaveconvex structure on those wave inclined platforms 21 and the 22 formation inner lining structure surfaces, low-lying district that are positioned at every wave inclined platform 21 both sides.
When the ball mill normal operation, abrasive media in the ball mill barrel and raw material are along with cylindrical shell turns round by certain speed, in the process of running, the abrasive media in the cylindrical shell and raw material mutually clash into and grind, and make raw material that physical change broken and that grind occur; The path that part abrasive media extends along wave inclined platform and low-lying district move or the slope on the circular arc band make the normal direction direction, increased the impacting direction to raw material, thereby improved the crushing efficiency of raw material; The direction that raw material and abrasive media are well evenly mixed and extend along low-lying district evenly distributes to the ball mill barrel two ends, reduces the eccentric force of ball mill barrel when the work running, lowers the work revolution electric current, reaches energy-saving and cost-reducing purpose.The transition arc of wave inclined platform adopts the large cambered surface that matches with the ballstone radius, has greatly improved the contact area of liner plate and abrasive media, i.e. also corresponding increase of the area of milling zone, thereby the grinding efficiency of raising raw material; The setting of wave inclined platform makes ball mill to the fragmentation of material and grinds and requires to have carried out rational distribution, the wave inclined platform partly is mainly used in fragmentation, low-lying district then is mainly used in grinding, make grinding more fully, effectively, further improved grinding efficiency, shorten milling time, reached energy-conservation purpose.
