ジャイレトリ・シフタの性能に関する研究 : 第2報,モデル化

抄録

Motion of a powder bed is analyzed by assuming a simplified model to study the sifting mechanism of a gyratory sifter. Analysis shows that the relative motion of the bottom of the power bed with respect to the sieve diminishes as the bed depth increases. The sifting rate, or the particle flow through a sieve, is treated in a manner analogous to that for the fluid flow through an orifice. The proposed model shows general agreement with the experiment though the experimental results are more dependent on revolving speed than the analytical ones.
