PURPOSE: To predict a raw material easy to vibrate by forming a granular body as a sample obtained by powdering or granulating a raw material, exerting a compressive force and a shearing force on the layer to obtain the shearing and collapsing characteristics in the layer and predicting the vibrating level of a vertical mill based on the obtained characteristics. ;CONSTITUTION: A vertical force 23 is exerted on a test powder 1 by a load cell 15, a shearing load 27 is applied by a load cell 10 in a shearing tester, and hence the vertical stress and shearing stress are simultaneously and continuously measured. The obtained uniaxial collapsing stress (f)-compression stress σ1 relation is considered to be the internal shearing and collapsing characteristics. When the stress (f) is larger than a specified value, the raw material is predicted as difficult to vibrate, and the raw material is predicted as easy to vibrate when the stress (f) is smaller than another specified value.;COPYRIGHT: (C)1994,JPO&Japio
