The invention relates to a crusher, especially an ultrasonic- and mechanically stirring- crushing combined ultrasonic crusher for crushing metallic or nonmetallic material. It fixes an ultrasonic generating tube around the stirring tube, and there is a water inlet and a water outlet at the bottom of and on the top of the ultrasonic generating tube, respectively; and there are ultrasonic emitters uniformly distributed around the ultrasonic generating tube. Its crushing is nano-level, its structure is simple and its manufacture is convenient.
Description
(1) Technical field [0001] The invention relates to a pulverizer, in particular to an ultrasonic pulverizer combining ultrasonic pulverization and mechanical agitation pulverization. (2) Background technology [0002] With the development of science and technology, the particle size of the powder required by people is getting smaller and smaller, and some powders need to reach the nanometer level. Especially with the deepening of the understanding of nanomaterials, various excellent properties of nanomaterials have been discovered, and the application of nanomaterials has become more and more extensive. Due to the limited function of the currently used mixing and pulverizing machines, the particle size of the produced powder is relatively too large to meet the needs of people in specific situations. For example, the Chinese patent No. 87213972: "ultrasonic cell pulverizer" discloses a cell pulverizer utilizing ultrasonic waves to pulverize organic matter. Since the organic...
