Opposed jet mill sorter having modification function and mill sorting system

Abstract

The present invention provides an opposed jet mill sorter having a modification function and a mill sorting system. The jet mill sorter comprises a cavity, a material outlet arranged on the top of the cavity, and a sorting part arranged on the bottom of the f the cavity, wherein the cavity is provided with at least a pair of material feeding nozzles, the material feeding nozzles are oppositely arranged on side walls of the cavity, the bottom of the sorting part is provided with a residue discharging port, the outer wall of the sorting part is provided with a gas inlet, and an air distribution plate is arranged between the cavity and the sorting part. With the present invention, modification can be simultaneously performed during the material milling process, the difficultly milled material can be timely eliminated, and power consumption during the mill process can be reduced.

Description

technical field

[0001] The invention relates to a colliding jet mill, in particular to a colliding jet milling and sorting machine with modification function and a pulverizing and sorting system. Background technique

[0002] Powder technology is regarded as one of the most important basic technologies to support high-tech industries. After the particles are refined, the specific surface area is large and evenly distributed, showing many excellent properties. It is used in fillers, dyes, pigments, medicines, catalysts, magnetic Widely used in memory components, advanced abrasives, solid lubricants, fine ceramics, cosmetics, etc.

[0003] The methods of obtaining ultrafine powder are mainly chemical and mechanical methods. The chemical method is only used in a few special fields due to its complicated process and high cost; while the mechanical pulverization method is low in cost, high in output, simple in process, and can improve materials. It is widely used due to its adva...
