    • The object is that of providing a granular material processing apparatus (1) capable of evenly applying energy such as the compressive force and shearing force of pressers (5), due to centrifugal force, while maintaining good circulation conditions for the swirl flow of granular material within a casing (3) wherein, even in cases where granular material for which it is difficult to control the flow thereof in the casing (3) is processed, this is not allowed to accumulate in once place within the casing (3), but is moved to the entire interior wall thereof. In the cylindrical region formed in accordance with the revolution of the pressers (5) in the casing (3), an empty region (6) is formed wherein there is no extension of a shaft (201) etc., allowing for the formation of a center of swirl flow of the granular material; the rotation of the casing (3) and the rotation of a rotor (4) can be rotationally controlled in the same direction at differing speeds; and the pressers (5) are horizontally supported in a cantilevered manner on the rotor (4).
    • 目的在于提供能够均匀地施加诸如压力(5)的压缩力和剪切力的能量的粒状材料处理装置(1),由于离心力,同时保持颗粒状物质的涡流的良好的循环条件 在壳体(3)内,即使在处理难以控制其在壳体(3)中的流动的粒状材料的情况下,也不能一次性地在壳体(3)内积聚,但是 移动到其整个内壁。 在根据壳体(3)中的按压(5)的旋转而形成的圆筒区域中,形成有空的区域(6),其中不存在轴(201)等的延伸,从而允许形成 颗粒材料的涡流中心; 壳体(3)的旋转和转子(4)的旋转可以以不同的速度以相同的方向旋转控制; 并且压脚(5)以悬臂方式水平地支撑在转子(4)上。
