Abstract
The utility model discloses a stirring rod for a stirring ball mill. A main body of the stirring rod is a cylindrical rod, the surface of the cylindrical rod is provided with semispherical bulges, the stirring rod is fixed on a stirring shaft of the stirring ball mill, and the semispherical bulges are arranged in a staggering manner. The stirring rod has the effects that the contact area of the stirring rod can be increased due to the semispherical bulges, the ball grinding speed can be accelerated, and the stirring rod is not easy to be worn; and due to adoption of the arrangement mode of the semispherical bulges, the ball grinding speed of the stirring rod can be increased.
Description
Technical field
Embodiment of the present utility model relates to the ball grinding technique apparatus field of dry powder and wet powder, and more specifically, embodiment of the present utility model relates to a kind of stirring rod for agitating ball mill.
Background technology
In the tradition powder-making technique, with respect to the standby higher efficient of roller milling facility, and the powder size relatively concentrated advantage that distributes is widely used agitating ball mill due to it.The conventional shape of the stirring rod of agitating ball mill is a cylinder, and cylinder is smooth, and stirring rod is fixed on shaft.In mechanical milling process, the rotation of shaft middling speed makes mill ball fully mix with powder, helps even grinding, and enhances productivity.But, traditional stirring rod in the course of the work, work contact-making surface be the periphery of stirring rod, contact area is less, contact-making surface is smooth, and in mechanical milling process stirring rod be vulnerable to wearing and tearing.
The utility model content
The utility model has overcome the deficiencies in the prior art, and a kind of embodiment of the stirring rod for agitating ball mill is provided, and solves with expectation the shortcoming that the stirring rod contact area is little, be vulnerable to wear and tear.
For solving above-mentioned technical problem, a kind of embodiment of the present utility model by the following technical solutions:
Provide a kind of stirring rod for agitating ball mill in an embodiment of the present utility model, the main body of described stirring rod is cylindrical rod, and the surface of described cylindrical rod has hemispherical projections, and described stirring rod is fixed on the shaft of agitating ball mill.
Further technical scheme is, described hemispherical projections is staggered on the surface of cylindrical rod.
Further technical scheme is, the radius of described hemispherical projections is 0.3～0.5 times of cylindrical rod diameter.
Compared with prior art, one of the beneficial effects of the utility model are: hemispherical projections can increase the contact area of stirring rod, accelerates ball milling speed, and stirring rod is difficult for being worn, and the arrangement mode of hemispherical projections also can increase the ball milling speed of stirring rod.
Description of drawings
Fig. 1 is the structure chart of a kind of stirring rod for agitating ball mill of the utility model.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
Traditional mixer makes the grinding rate of whipping process not high because its stirring rod is the cylindrical of smoother, and stirring rod easily is worn.As shown in Figure 1, the utility model is in order to address the above problem, the non-smooth surface with hemispherical projections 3 is revised as on smooth cylindrical stirring rod surface, and reaches the raising grinding rate by the arrangement to hemispherical projections 3, prevent the stirring rod texts that is worn.
The main body of the stirring rod that is used for agitating ball mill that the utility model provides is a cylindrical rod 2, and the surface of cylindrical rod 2 has a lot of hemispherical projections 3, and stirring rod is fixed on the shaft 1 of agitating ball mill.Hemispherical projections 3 can increase the contact area of stirring rod, and can make stirring rod be difficult for being worn, thereby reaches the purpose of accelerating agitation grinding speed.
According to an embodiment of the present utility model, the diameter of the shaft 1 of rotation is 60mm, and its rotating speed is 500～800rpm, and the diameter of the cylindrical rod 2 of stirring rod is 15mm, and the radius of the hemispherical projections 3 on it is 0.3 times of cylindrical rod 2 diameters, i.e. 4.5mm.Adopt the stirring rod of above-mentioned size to carry out ball milling to granularity less than 200 purpose iron powders, ratio of grinding media to material is 3:1, milling time needs 8 hours, iron particle size after grinding is 65% of raw material total amount in 180～200 order scopes, and adopting traditional stirring rod will reach identical crushing effect needs ball milling about 12 hours.Therefore, better to the crushing effect of powder with the stirring rod of hemispherical projections.
According to another embodiment of the present utility model, the diameter of the shaft 1 of rotation is 60mm, and its rotating speed is 500～800rpm, and the diameter of the cylindrical rod 2 of stirring rod is 15mm, and the radius of the hemispherical projections 3 on it is 0.5 times of cylindrical rod 2 diameters, i.e. 7.5mm.Adopt the stirring rod of above-mentioned size to carry out ball milling to granularity less than 200 purpose iron powders, ratio of grinding media to material is 3:1, milling time needs 7.9 hours, iron particle size after grinding is 64% of raw material total amount in 180～200 order scopes, and adopting traditional stirring rod will reach identical crushing effect needs ball milling about 12 hours.
The size of shaft 1, cylindrical rod 2, hemispherical projections 3 etc. is not limited to above-described embodiment.But when being 0.3～0.5 times of cylindrical rod 2 diameters, usually can bring into play the radius of hemispherical projections 3 its best ball milling effect.
Although with reference to explanatory embodiment of the present utility model, the utility model is described here, but, should be appreciated that, those skilled in the art can design a lot of other modification and embodiments, and these are revised and within embodiment will drop on the disclosed principle scope and spirit of the application.More particularly, in the scope of, accompanying drawing open in the application and claim, can carry out multiple modification and improvement to building block and/or the layout of subject combination layout.Except modification that building block and/or layout are carried out with improving, to those skilled in the art, other purposes will be also obvious.
