Abstract
The utility model relates to a grinding medium and particularly relates to a medium aluminum ball with uniform density and high wear resistance. The medium aluminum ball is characterized in that the medium aluminum ball is a solid ball and is sequentially composed of a wear resistant layer, an intermediate layer and a core layer from outside to inside; the thickness of the wear resistant layer is 0.2-0.3 of the radius of the medium aluminum ball; the wear resistant layer, the intermediate layer and the core layer are all made of alumina powder; and the densities of all the layers are sequentially decreased from outside to inside. Compared with the medium aluminum ball in the prior art, the medium aluminum ball provided by the utility model is high in wear resistance, uniform and consistent in density, high in ball milling performance and low in cost.
Description
Technical field
The utility model relates to a kind of grinding medium, specifically is aluminium ball in a kind of high abrasion of density homogeneous.
Background technology
Aluminium ball (alumina content 〉=70%), high aluminium ball (alumina content 〉=95%) and siliceous ball during alumina balls can be divided into according to different alumina contents.High aluminium ball density is big, volume is little, and having high strength, high rigidity, high-wearing feature, excellent specific property such as high temperature resistant, corrosion-resistant, pollution-free, its weak point is the price height, the general use seldom, and siliceous ball is because the abrasion loss maximum, price is minimum, so also seldom adopt middle aluminium matter ballstone moderate cost, abrasion loss is also less, so be that most of producers are selected a few days ago.In the aluminium ball is general adopts discarded or material preparations such as the refractory materials that reclaims, high alumina brick, on the market a lot of in aluminium ball wear resistancies can't reach service requirements, in addition, adopt the middle aluminium ball density uniformity of salvage material preparation bad, influenced the ball milling performance.
Summary of the invention
The utility model provides aluminium ball in a kind of high abrasion of density homogeneous, and its wear resistance is good, the density uniformity, and cost is low.
The concrete technical scheme that adopts of the utility model is:
The aluminium ball is characterized in that in a kind of high abrasion of density homogeneous, and described middle aluminium ball is a solid sphere, and it is made of wearing layer, middle layer and sandwich layer from outside to inside successively, and the thickness of described wearing layer is 0.2～0.3 of the middle aluminium radius of a ball; Described wearing layer, middle layer and sandwich layer are made by aluminum oxide powder, and each layer density is successively decreased from outside to inside successively.
Method for making of the present utility model is: raw material is according to the alumina content classification, and uniform mixing has the machine burning lost article in raw alumina powder at different levels, and static pressure such as employing become mandrel layers, middle layer and wearing layer successively, and last routine is burnt till promptly.
Compared with prior art, the utility model has the advantages that:
1) wearing layer of the present utility model adopts the aluminum oxide powder of alumina content 〉=95% to make, and cost is lower than high aluminium ball, but has the high-wearing feature of high aluminium ball;
2) through applicant's test, the utility model wearing layer thickness is suitable, can in use not be worn through;
3) wearing layer, middle layer and sandwich layer density become Gradient distribution, make that middle aluminium ball consistent in density of the present utility model is good, and nonferromagnetic substance is good.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure, 1-wearing layer, 2-middle layer, 3-sandwich layer.
Embodiment
As shown in Figure 1, middle aluminium ball is a solid sphere, is made of wearing layer 1, middle layer 2 and sandwich layer 3, and the thickness of described wearing layer 1 is 0.2～0.3 of the middle aluminium radius of a ball.Wearing layer 1, middle layer 2 and sandwich layer 3 all have aluminum oxide powder to make, and its density is successively decreased successively.
