Method for separating metal powder off line

Abstract

The invention provides a method for separating metal powder off line, which is used for multi-pass classification of the metal powder to form products with different particle sizes. The method comprises the following steps that: the metal powder is classified by a classifier, and the metal powder with a first particle size enters a first collecting bin; the residual metal powder enters a first-stage cyclone classifier, and the metal powder with a second particle size enters a second collecting bin; the residual metal powder enters a second-stage cyclone classifier, and the metal powder with a third particle size enters a third collecting bin; the residual metal powder which passes through the second-stage cyclone classifier enters a third-stage cyclone classifier, and the metal powder with a fourth particle size enters a fourth collecting bin; and the residual metal powder enters a dust removing box, and the metal powder with a fifth particle size enters a fifth collecting bin. By the method for separating the metal powder off line, the production speed is improved, the particle size distribution of the products is narrower, the particle size of the powder is more uniform, the aims of improving product quality and enriching product specifications are fulfilled, and manpower and material resources are saved.

Description

technical field [0001] The invention relates to a realization method of an industrial process, in particular to an off-line separation method of metal powder. Background technique [0002] Metal powders are used in many industrial productions, but different production requirements require metal powders of different sizes, so the metal powders need to be separated. [0003] The production of traditional metal powder mainly depends on the ball mill production line, and the product quality is greatly affected by the equipment and process parameters of the ball mill system. Due to the limited classification efficiency of the current classifier on the ball milling line, it is difficult to produce high-quality metal powder products with a narrow particle size distribution, and the produced metal powder products have a single specification, which is difficult to meet the market demand for high-end metal powder and metal powder with diversified specifications The needs of the p...
