Micro powder jet mill

Abstract

The invention relates to a micro-powder airflow mill. The micro-powder airflow mill is characterized in that an adjusting gasket and a sorting wheel are arranged on a motor spindle; a motor base is fixedly connected to an upper cover; the upper cover is fixedly connected to a supporting plate of a mill chamber outer shell; the periphery of the motor base is connected with a plurality of air connectors; a mill chamber inner shell is arranged in the mill chamber outer shell; a cavity of the mill chamber inner shell serves as a mill chamber; the bottom of a nozzle fixing disc of the mill chamber inner shell is fixedly connected with a plurality of nozzles; the nozzle fixing disc of the mill chamber inner shell is arranged on a bottom disc; the lower end of the bottom disc is fixedly connected with auxiliary air connectors; the multiple auxiliary air connectors are fixedly connected to an auxiliary air connector fixing seat; a discharging bush is arranged in the center of the nozzle fixing disc and the center of the bottom disc; a clearance is arranged between the end face of the sorting wheel and the end face of the nozzle fixing disc; a feeding mechanism and an air inlet pipe are fixedly connected to the outer circumference face of the mill chamber outer shell; and the lower end of the discharging bush is connected with a finished product discharge opening. The micro-powder airflow mill is reasonable in structure, the material particle size distribution concentration ratio can be effectively increased, product quality is good, and cost is low.

Description

technical field [0001] The invention relates to powder crushing equipment, in particular to a fine powder jet mill. Background technique [0002] In the prior art, for material pulverization, mechanical pulverization or jet milling are usually used to meet the requirement of powder particle size. However, the concentration of particle size distribution of powder produced by all these milling methods is not very ideal, and the proportion of ultrafine powder is relatively large, which seriously affects the quality of the product. In addition, the ultra-fine powder that does not enter the finished product reaches the filter with the air flow. The filtration of the ultra-fine powder will increase the power consumption and the loss of the filter element, the yield rate is low, and the cost of the finished product is increased. [0003] Existing jet mills, for example: Chinese Patent Application Publication No.: CN 105312144 A discloses "Ultrafine Airflow Classification Mill", wh...

Problems solved by technology

Its invention solves the problem of remaining powder in the container, but due to its collision components, the proportion of superfine powder will be high, and the structural characteristics of crushing and sorting inside the container lead to a low concentration of particle size distribution
