Problems solved by technology

[0003] However, due to intermolecular forces and other reasons, during the working process of the planetary ball mill, the samples are prone to stick to the wall and agglomerate, which makes it impossible to efficiently grind the sample to the specified size when the planetary ball mill is working.

Abstract

The invention discloses a planetary vibration ball mill, and belongs to the field of ball mills. The planetary vibration ball mill comprises a base with the upper end open. A main motor is arranged inthe base. An output shaft of the main motor is connected with a rotating shaft at the lower end of a rotating disc. A driving gear on the rotating shaft is engaged with a planetary gear on a planetary shaft. The upper end of the planetary shaft penetrates through the rotating disc to be connected with a milling tank base. A ball milling tank is placed in the milling tank base. A support is arranged at the lower end of the main motor. An auxiliary motor is arranged in the base and located below the support. An output shaft of the auxiliary motor is connected with a driving shaft. The driving shaft is arranged in a non-horizontal mode and used for driving one side of the support to ascend and descend vertically. According to the planetary vibration ball mill, the phenomena of wall sticking,agglomeration and the like of samples during the working of the planetary ball mill can be reduced.

Description

technical field [0001] The invention relates to the field of ball mills, in particular to a planetary vibration ball mill. Background technique [0002] Planetary ball mill is an essential device for mixing, fine grinding, sample preparation, nanomaterial dispersion, new product development and small batch production of high-tech materials. When the planetary ball mill is working, multiple ball milling jars and rotating discs form a planetary motion, and the ball milling jars are self-propagating to drive the grinding balls in the ball milling jars to collide with each other at high speed, and the grinding balls in the jars collide with each other in high-speed motion to grind and mix samples. [0003] However, due to intermolecular forces and other reasons, the samples tend to stick to the wall and agglomerate during the working process of the planetary ball mill, which makes it impossible to efficiently grind the sample to the specified size when the planetary ball mill is...
