Turbulence Mill Preliminary Research

This paper regard turbulence mill as research object, recommend ultra-fine crush equipment and the trend of ultra-fine comminution technology, explain the necessity of studying turbulence mill. It have summered up the theory of crushing that turbulence mill use partly, clarify the crush mechanism of this kind of comminution. The paper propose a new view of fatigue comminution in favor of ultra-fine comminution through researching gongj's theory of fatigue comminution. Through experiment, it described the relation of turbulence mill rotational speed and comminution effect; Proving that the turbulence mill have a economic rotational speed ;Proving there is a optimal distance between impellers under the specific rotational speed ; Proving that the time of staying in turbulence mill affect importantly the products grain size and distributing. Through comminuting thermoplastic, lily and angelica, the result illustrate that turbulence mill can comminute thermoplastic under normal temperature ;Proving the turbulence mill is fit to crush Chinese traditional medicine,it can conglobate fibre of powder to benefit the classification.
