Study On The Technology And Application Of High-Speed Cutting Comminution

This paper regard the technology of high-speed cutting comminution as researching object. recommends ultrafine crush equipment and the trend of ultrafine crush comminution technology, explains the necessity of studying and devising high-speed cutting comminution equipment. It have summered up the theory of crushing use partly. And particularly clarified the crush mechanism of this kind of comminution combine with grain part theory. The paper proposes a view of high-speed and compaction in favor of cutting comminution through researching theory of grain part. Through analysis of parameters of operation and structure, have been the relative factors that impact of crush effect discussed. The flow field of cutting comminution is simulated and analysed by computational fluid dynamics software FLUENT. From which we received the impeller form and deflexion angle of blade most in favor of cutting comminution, and proved that the high-speed cutting comminution have a economic rotational speed. Using of the ANSYS software, the model of the key component of the high-speed cutting comminution equipment——rotor is established. The distortion of the rotor with the high rotating speed is obtained. The result of the probability analysis is gotten. Considering the conditions we have, cooperate with QingDa food equipment company manufactured an experiment equipment of high-speed cutting comminution. The result of comminuting peanut and kelp illustrate that high-speed cutting comminution equipmen is fit for the material with high level of fibre. Its capability excells that of high-speed shearing equipment. The equipment is fit to process the material used in food, commodity and medication production.The analysis of mechanism, numerical simulation of crush flow filed, probability of rotor and experiment, provide concepts and datas reference for the following steps and research of high-speed cutting comminution, and lay a foundation for the development of the equipment based on the technology of high-speed cutting comminution.
