Description

Technical Field

[0001] The utility model belongs to the technical field of ball mill maintenance, and particularly relates to a grinding ball screening device. Background Art

[0002] A ball mill is a device used to crush materials. A plurality of different crushing chambers are provided in the ball mill. The diameters of the grinding balls placed in different crushing chambers are also different. The diameters of the grinding balls will shrink after long-term use. Therefore, the grinding balls need to be taken out and placed in different crushing chambers according to their diameters. In the existing technology, the grinding balls are distinguished manually, which is not only inefficient, but also depends solely on visual observation, resulting in large errors, which affects the use of the ball mill. Utility Model Content

[0003] In view of the above problems, the utility model provides a grinding ball screening device.

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0005] A grinding ball screening device includes a plurality of partitions arranged in sequence from high to low, two side plates are fixed to the upper ends of the plurality of partitions, a plurality of guide rods are arranged between the two side plates, the guide rods are fixedly connected to the partitions, and the spacing between the guide rods gradually increases from high to low. Grooves are provided between adjacent guide rods on the upper surface of the partitions to facilitate the passage of grinding balls, a No. 1 inclined collecting plate is fixed between adjacent partitions for sending out the screened grinding balls, a No. 2 inclined collecting plate is fixed at the rear end of the last partition, and legs are fixed to the lower surface of the No. 1 inclined collecting plate to support the entire device.

[0006] Furthermore, guide plates are fixedly provided on the discharge sides of the No. 1 inclined material collecting plate and the No. 2 inclined material collecting plate to facilitate the collection of the grinding balls.

[0007] Furthermore, a buffer plate is fixedly connected to the front end of the first partition, and a support leg is fixed on the lower surface of the buffer plate. The buffer plate is used to buffer the grinding balls that need to be screened, so that the grinding balls roll in an orderly manner between the guide rods, preventing the grinding balls from stacking on the guide rods when being poured in, thereby affecting the screening effect.

[0008] Compared with the prior art, the utility model has the following advantages:

[0009] When the utility model is used, the grinding balls roll down from the upper ends of the guide rods, and the spacing between the guide rods gradually increases from high to low, thereby realizing the distinction between grinding balls of different diameter ranges, and effectively improving the screening efficiency and screening accuracy of the grinding balls;

[0010] The utility model is provided with a buffer plate to buffer the poured grinding balls. The buffering of the buffer plate enables the grinding balls to roll between the guide rods in an orderly manner, thereby preventing the grinding balls from piling up on the guide rods and affecting the screening effect of the grinding balls. BRIEF DESCRIPTION OF THE DRAWINGS

Grooves 4 are provided between adjacent guide rods 3 on the upper surface of the partitions 1 to facilitate the passage of grinding balls. A buffer plate 9 is fixedly connected to the front end of the first partition 1, and a support leg 7 is fixed to the lower surface of the buffer plate 9. The buffer plate 9 is used to adjust the required The screened grinding balls are buffered so that they roll in an orderly manner between the guide rods 3 to prevent the grinding balls from stacking on the guide rods 3 when being poured in, thereby affecting the screening effect. A No. 1 inclined collection plate 5 is fixed between the adjacent partitions 1 to send out the screened grinding balls. A No. 2 inclined collection plate 6 is fixed at the rear end of the last partition 1. Guide plates 8 are fixed on the discharge sides of the No. 1 inclined collection plate 5 and the No. 2 inclined collection plate 6 to facilitate the collection of grinding balls.
