Струйная мельница

Jet Mill Operating principle Jet mill, with cyclone separator and radial fan, consists of a complete powder grinding system. Compressed air after being dried is injected into crushing cavity quickly by the injection of valves. At connection points of many high-pressure air currents, feed materials are collided, rubbed and sheared repeatedly to powders. The crushed materials go into classifying cavity with uprising air flow, under the condition of lashing forces of radial fan. Under strong centrifugal forces of high-speed rotating turbo wheels, coarse and fine materials are separated. Fine materials in line with size requirements go into cyclone separator or dedusting filter through classifying wheels, while coarse materials fall down to crushing chamber to be crushed continuously. Performances and Features -Suitable for materials with Mohs' hardness <9, especially super-hard, super-pure and high extra-value materials. -Horizontal classifying installation. Accurate top point cutting. Particle size: D97: 8um-150um, adjustable, good shape and narrow size distribution. -Low temperature, no medium rushing, especially for heat-sensitive, low-melting point, sugar-containing and volatilized materials. -Feed materials impact by themselves, different from others which use hammer and razor blades. Wear-resistance and high purity. -Easily to be dismantled, smooth inside wall and no dead angle.
