Benefits of technology

This technology helps improve the separation efficiency for different types of granular or solid waste materials during recycling processes. It uses an oscillator called a spray gun connected between two pipes filled with liquid (powders) before they enter the machine's feed channels. By injecting compressed gas onto these droplets at high velocity, it causes them to break apart and separate larger pieces of waste. These smaller fragments may also pass downstream without being further processed. Overall, this technology improves efficient sorting techniques used in various industries such as manufacturing industry.

Problems solved by technology

This patented technical problem addressed in this patent relates to improving the quality control standards needed when producing small amounts of material used in various industries like military applications where strict limits on contaminant levels can affect performance. Current methods require expensive equipment which may result in unclean surfaces due to imperfections during production processes.

Abstract

The invention provides a jet mill for ultra-fine powder. The jet mill for ultra-fine powder can meet requirements of processing of multiple materials, fine pulverization is realized, and thus, the jetmill for the ultra-fine powder effectively adapts to technical development. The jet mill for the ultra-fine powder comprises a hopper, a charging device, a pulverizing device and a classifying device, wherein the hopper is connected with the pulverizing device via a channel; the classifying device comprises a classifier; an ejector is arranged at the inlet of the channel; the bottom of the channel communicates with a supporting box; an airflow opening is formed in the supporting box; the pulverizing device comprises variable-cross-section circulating tube which communicates with the channel and is positioned above the supporting box; a nozzle is arranged on the portion, which is connected with the channel, of the variable-cross-section circulating tube; the axis of a nozzle blowing direction is tangential to the central line of the variable-cross-section circulating tube; the upper portion of the variable-cross-section circulating tube communicates with a classifier; the classifier isconnected with an inner tube; and a discharging opening is formed in the inner tube.
