摘要： A multiple stage mixer including a pair of mixing chambers in communication with each other for the transfer of material therebetween and a rotary mixing element in each chamber movable on a path overlapping into the adjacent chamber in selected normal phase relation with respect to the mixing element therein. A source of motive power for rotatively driving said mixing elements and control means for rendering said motive power source ineffective when said mixing elements are out of said normal phase relation with each other is provided in order to prevent damage to the mixer in the event the phase relation between the mixing elements becomes abnormal.
摘要翻译：一种多级混合器，包括一对彼此连通以便在其间传送材料的混合室，以及每个室中的旋转混合元件，其可在相对于混合元件选定的正相关的重叠在相邻室中的路径上移动。提供用于旋转驱动所述混合元件的动力源和用于使所述动力源在所述混合元件彼此超出所述正常相位关系之前不起作用的控制装置，以便在相位相反的情况下防止损坏混合器混合元件之间的关系变得异常。
