Problems solved by technology

Set the sedimentation time with a fixed clock according to the particle size. After the sedimentation time is up, manually extract the required particle size, add water, stir, and repeat the cycle. This classification method is very inefficient, and the obtained product has a large particle size distribution range. Unevenness, many impurities, and time error caused by human factors, the influence of dust and other pollutants in the air may lead to the pollution of diamond powder. In addition, this classification method requires the use of a large amount of clean water, which has caused serious water resources. waste

Abstract

The invention discloses an overflow-circulation classification method for diamond micro-powder, belongs to the technical field of diamond production, and solves the defects of low production efficiency, large particle size distribution and high impurity content in the prior art. The overflow-circulation classification method for the diamond micro-powder comprises the following steps: (1) setting a water pressure and a flow rate of an overflow, and carrying out constant-pressure water supply by a constant-pressure water supply system; (2) carrying out overflow classification for the diamond micro-powder by an overflow classification system; and (3) carrying out precipitation classification by a precipitation water storage system to obtain the diamond micro-powder with the needed particle sizes. The method disclosed by the invention has high production efficiency and less interference of human factors; and the produced diamond micro-powder are centralized in distribution, uniform in particle sizes, and low in impurity content.

Description

technical field [0001] The invention relates to a diamond powder overflow circulation classification method, which belongs to the technical field of diamond production. Background technique [0002] The traditional method of sorting diamond micropowder is to feed 5000 carats into a 5000ml beaker or a plastic bucket, add water to the scale, use a plexiglass rod to manually stir and then back-stir until the water surface is calm, and then clean the beaker wall. Set the sedimentation time with a fixed clock according to the particle size. After the sedimentation time is up, manually extract the required particle size, add water, stir, and repeat the cycle. This classification method is very inefficient, and the obtained product has a large particle size distribution range. Unevenness, many impurities, and time error caused by human factors, the influence of dust and other pollutants in the air may lead to the pollution of diamond powder. In addition, this classification method ...
