Flow Properties of Powder [PDF]
Japanese Journal of Applied Physics, 1963 A study on flow of powder is made with the aid of a double-cylinder type viscometer. Rotating the outer cylinder, the torque exerted on the inner cylinder and the amplitude of torque fluctuation are measured. Two types of flow are observed: theparticle-flowin which every powder particle moves as an independent unit, and theblock-flow, in which the ...
