Ultra-fine powder processing device

Abstract

The invention discloses an ultra-fine powder processing device which comprises an air flow crushing mechanism, a turbine grading mechanism, a screw feeder, an automatic sack packer, an automatic controller, a bag type dust collector, an integrated platform, an induced draft fan and a gas path controller, wherein the air flow crushing mechanism connected with the turbine grading mechanism is located below the turbine grading mechanism, the feed port of the screw feeder is connected with a feed taper pipe in the air flow crushing mechanism, the bag type dust collector is connected with the turbine grading mechanism through a pipeline, the automatic sack packer is located below the bag type dust collector and the induced draft fan is connected with the bag type dust collector. The ultra-fine powder processing device can process materials in a fully-closed condition without producing dust. The ultra-fine powder processing device uses a PLC control system to intelligentize the production process and adjusts the parameters of crushing, grading and other devices according to the factory production requirements so as to meet the crushing requirements of different raw materials. The processing device is built on a stand, and the position of the processing device can be adjusted according to the factory production requirement.

Description

technical field [0001] The invention relates to the field of powder preparation and processing, in particular to an ultrafine powder processing device and method thereof. Background technique [0002] Jet crushing is to use the huge kinetic energy bred by the high-speed airflow generated by the high-pressure airflow through the nozzle, so that the object particles collide with each other or collide with the fixed object to achieve the purpose of crushing. Professor Rumpf of Karlsruhe University in Germany, in the 1950s and 1960s, made a great contribution to the development and application of jet milling technology on the basic theoretical research of mechanical powder preparation. In the 1970s and 1980s, for powder In order to solve the problems of fineness and purity in powder processing, the United States, Japan, Europe and other countries have researched and developed the fluidized bed jet mill, which provides a powerful ultra-fine powder processing method for many indus...
