A planetary ball mill for soil sample preparation

Abstract

The invention provides a planetary ball mill for soil sample preparation, comprising a planetary turntable, a plurality of ball mill jars and a plurality of jar holders, wherein the jar holder comprises a base, a first holder, a second holder and an elastic tensioning mechanism , lock belt, lock assembly and locking mechanism. The planetary ball mill used for soil sample preparation abandons the use of bolt pressing rod mechanism in traditional equipment to fix the ball mill jar in the jar holder, saves the operation process of repeatedly tightening or loosening the bolts, and the fixing method of the ball mill jar. It is more convenient, and on the premise of improving the disassembly and assembly speed of the ball mill jar, it also ensures that the ball mill jar is effectively fixed, thereby improving the work efficiency and safety of the grinding process in soil sample preparation.

Description

technical field [0001] The invention relates to the technical field of soil sample preparation equipment, in particular to a planetary ball mill for soil sample preparation. Background technique [0002] Environmental chemistry is a science that uses chemical theories and methods to study the identification and determination of potentially harmful and toxic chemical substances in the atmosphere, water, and soil environments, the existence of pollutants, the laws of migration and transformation, ecological effects, and the reduction or elimination of their production. One of the important branches of environmental science. [0003] In the determination of soil, the preparation of soil samples is the most important and joint link in soil analysis. The preparation process of soil samples generally includes: air-drying, screening, coarse grinding, fine grinding, and sieving. Among them, in order to make the soil particles of the soil samples uniform, a planetary ball mill is us...

Problems solved by technology

[0005] At present, bolts and pressure rods are usually used to fix the ball mill tank in the tank support of the planetary turntable. However, the operation of this fixing structure is relatively complicated, and the experimenter needs to perform multiple operations of tightening or loosening the bolts, so as to achieve the tightness of the pressure rod. Or the purpose of loosening the ball milling tank, which not only results in low efficiency in disassembling and assembling the ball milling tank, but at the same time, due to the different strengths used by each person, the tightening degree of the bolts cannot be guaranteed, thus posing a safety hazard
