Problems solved by technology

[0003] The inner walls of the ball mill jars used in planetary ball mills in practical applications are all smooth and curved. The grinding action between the ball mill jar and the powder makes the powder crush and mix. The impact effect is not very significant, so the grinding efficiency is low. Grinding quality is not high

Embodiment 1

[0032] Such as Figure 1-Figure 4 As shown, a ball milling tank includes a tank cover 1 and a tank body 2, the tank body 2 has a non-cylindrical side wall inner wall 21, and the tank bottom 22 of the tank body 2 has a plurality of tank bottoms 22 The center is the protrusions 23 evenly distributed in the center.

[0033] The orthographic projection of the protrusion 23 on the tank bottom 22 is a kite-like shape 24, and there are common sides between adjacent kite-like shapes 24, that is, each of the kite-like shapes 24 includes A common side I241 and a common side II242, one end of the common side I241 and the common side II242 coincides with the center of the tank bottom 22, and the other end is located at the end of the asymmetrical axis diagonal line 243 of the kite-like shape 24;

[0034] The protrusion 23 has a symmetrical edge 231 corresponding to the symmetric axis diagonal line 244 of the kite-like shape 24 and an asymmetric edge 232 corresponding to the asymmetric ax...

Embodiment 2

[0048] Such as Figure 5 As shown, a planetary ball mill containing the ball mill jar described in Example 1 includes a drive motor 5, a transmission mechanism 6, a revolving turntable 7 located on the transmission mechanism 6, and a plurality of revolving turntables 7 located on the revolving turntable 7 The rotation shaft 8 on the top, the said rotation shaft 8 is provided with the ball mill jar as described in embodiment 1, the output end of the said driving motor 5 is connected with the input end of the said transmission mechanism 6 through the belt pulley 9, the said rotation shaft 8 The axis is parallel to and not coincident with the axis of the ball mill jar.

[0049] Use the ball mill jar described in Example 1 and the same material ball mill jar (contrast ball mill jar) that the inner wall of the side wall is a smooth cylindrical surface to grind the limestone blocks that are 300g in quality and have the same shape, stop every 60 seconds, and use A 200-mesh sieve scr...

Abstract

The invention discloses a ball-milling tank and a planetary ball mill with the same. The ball-milling tank comprises a tank cover and a tank body. The tank body is provided with a non-cylindrical-surface side wall inner wall, and the tank bottom of the tank body is provided with a plurality of protrusions which are evenly distributed by using the center of the tank bottom as a center. According to the ball-milling tank and the planetary ball mill with the same, the tank bottom of the ball-milling tank of the ball mill is designed to be provided with the rhombus protrusions, the contact area of the tank bottom and abrasive is increased, and the tank bottom is turned to be provided with fixed grinding balls participating in the grinding process of the abrasive; the rubbing action of the tank bottom and the abrasive is increased, and the impact force and impact frequency of the abrasive are greatly increased; due to the fact that the inner wall of the side wall of the ball-milling tank is designed into the non-cylindrical-surface side wall inner wall, mold withdrawing is conducted outwards, the abrasive is pushed to the tank bottom under the effect of centrifugal force, the grinding effect on the abrasive by the protrusions is improved, the grinding efficiency and quality of the planetary ball mill are greatly improved, and the property of an original planetary ball mill is improved.

Description

technical field [0001] The invention relates to the field of planetary ball milling devices, in particular to a ball milling pot and a planetary ball mill containing the ball milling pot. Background technique [0002] Ball mill is a common mechanical device for producing ultra-fine powder. At present, ball milling method is widely used in mineral processing, powder preparation and ceramic processing. It has a good effect on the grinding, fine grinding and fine grinding of powder materials. , The ball milling method has the characteristics of simple process and remarkable effect. [0003] At present, the inner wall of the ball mill tank used in the planetary ball mill in practical application is smooth and curved. The grinding action between the ball mill tank and the powder makes the powder body pulverized and mixed. The impact effect is not very significant, so the grinding efficiency is low. Grind quality is not high. Contents of the invention [0004] According to the...
