Embodiment

[0015] Example: see figure 1 , an inert gas-protected ultra-fine airflow pulverization unit, which is composed of an airflow system and a pulverization system. The arrow drawn on the figure is the direction of the airflow, and the device is fully enclosed;

[0016] The gas flow system is mainly composed of a protective gas source 1, a gas storage tank 2, and a gas compressor 3. The protective gas source 1 is connected to the gas storage tank 2, the gas storage tank 2 is connected to the gas compressor 3, and the protective gas from the gas compressor 3 is sealed in sequence. Flow to the fluidized bed jet pulverizer 4, the cyclone separator 7, the dust catcher 8 and finally get back to the inlet end of the gas compressor 3;

[0017] The crushing system is mainly composed of a fluidized bed jet mill 4, a feeder 6, a cyclone separator 7, and a dust collector 8. The feeder 6 is a star-shaped feeder with a sealing device, which can ensure sealing and uniform feeding. The feeder 6 ...

Abstract

A superfine airflow pulverizer system with inertial gas shielded for pulverizing the material to be oxidized easily is composed of airflow system and pulverizing system. Said airflow system consists of protective gas soorce, gas tank, compressor, fluidized-bed airflow pulverizer, cyclone separator, and dust capture. Said pulverizing system comprises sealed feeder, transition cabin, fluidized-bed airflow pulverzer, cyclone separator, and powder collector.

Description

technical field [0001] The invention relates to a material pulverizer. Background technique [0002] At present, the powder machine for crushing materials is fully open or half open, so that some easily oxidized materials cannot be crushed, and the powder quality will also be affected when crushing other materials. Contents of the invention [0003] In order to overcome the above-mentioned defects, the present invention provides an inert gas-protected ultra-fine jet milling unit capable of crushing oxidizable materials and having high powder quality. [0004] The technical solution adopted by the present invention in order to solve the technical problem is: this inert gas protection ultrafine airflow pulverization unit is composed of an airflow system and a pulverization system; [0005] The gas flow system is mainly composed of a protective gas source, a gas storage tank, and a gas compressor. The protective gas source is connected to the gas storage tank, the gas storag...
