Abstract
The utility model relates to an oval grinding ball; the oval grinding ball comprises a main body, wherein the main body comprises a big ball and a small ball; the diameter of the big ball is phi D; the diameter of the small ball is phi d; the big ball and the small ball are transitionally connected with each other by a smooth arc line; the ratio between the diameters phi D and phi d of the two balls falls within a range of 1:0.7-1:0.8; and the center distance L of the big ball and the small ball is equal to phi d. The oval grinding ball is made through experience accumulation according to wear statuses of the grinding balls in the long-time using process and summarized from long-time practical experience. The oval grinding ball with the shape, provided by the utility model, has the advantages of increased contact area, long service life and good grinding effect.
Description
Technical field
The utility model relates to a kind of abrading-ball, relates in particular to a kind of ovum shape abrading-ball.
Background technology
Ball crusher is widely used in the production fields such as cement, mining, building materials, chemical industry, electric power and pottery.The Main Function of ball crusher is with crushing material and grinding, to reach the desirable degree that mixes.Generally speaking, some abrading-balls are arranged in the ball crusher, by the continuous rolling compaction material of abrading-ball, make it to mix.Because abrading-ball is long-term and mixing of materials stirs and polishing, so the consumption of abrading-ball is also larger.Mostly existing abrading-ball is that casting forms, and is mostly circular, because contact area is little between abrading-ball and the material, production efficiency is low.
The utility model content
The deficiency that the utility model exists for prior art just provides a kind of ovum shape abrading-ball.
For addressing the above problem, technical solution adopted in the utility model is as follows:
A kind of ovum shape abrading-ball, comprise body, it is characterized in that, described body comprises the large ball that a diameter is φ D, a diameter is the bead of φ d, and large ball and bead are formed by connecting by round and smooth arc transition, the scope of the ratio of two sphere diameter φ D, φ d is 1: 0.7～1: 0.8, and the centre-to-centre spacing L=φ d of large ball and bead.
A kind of improvement as technique scheme: the end at large ball is provided with the first pit, is provided with the second pit in the end of bead.
The utility model compared with prior art, implementation result of the present utility model is as follows:
Ovum shape abrading-ball described in the utility model, according to wear condition in the long-term use procedure of abrading-ball and experience accumulation out, summarize the experience out by long-term practice.The ovum shape abrading-ball contact area of this shape increases to some extent, the abrading-ball long service life, and the abrading-ball rolling effect is good.

Fig. 2 is the utility model embodiment two described a kind of ovum shape abrading-ball front views;
Fig. 3 is the top view among Fig. 2;
Fig. 4 is the upward view among Fig. 2.
The specific embodiment
Content of the present utility model is described below in conjunction with specific embodiments.
As shown in Figure 1, be the utility model embodiment one described a kind of ovum shape abrading-ball structural representation.Ovum shape abrading-ball described in the utility model comprises body 1, and in fact body 1 comprises the large ball that a diameter is φ D, a diameter is the bead of φ d, and large ball and bead be formed by connecting by round and smooth arc transition, and the centre-to-centre spacing of two balls is L.The scope of the ratio of two sphere diameter φ D, φ d is 1: 0.7～1: 0.8, and the centre-to-centre spacing L=φ d of large ball and bead.
As shown in Figure 2, be the utility model embodiment two described a kind of ovum shape abrading-ball front views, Fig. 3 is its top view, and Fig. 4 is its upward view.Embodiment two with the main distinction of embodiment one is: the end at large ball is provided with the first pit 2, is provided with the second pit 3 in the end of bead.Like this with original point-to-point contact, or the contact of Line To Line changes aspectant contact into, increased like this contact area, more is conducive to rolling of abrading-ball, improved the abrading-ball rolling effect.
