ジャイレトリ・シフタの性能に関する研究 : 第1報,実 験

抄録

Experimental study of gyratory sifters, which are used to remove aggregate or alien substances, is presented. The effects of operating conditions, such as the bed depth of powder, the sieve revolving speed, and the size and shape of the sieve, on sifting capacity or sifting rate are investigated. The motion of the powder bed on a screening surface is also observed. Experimental results show that the sifting rate is very sensitive to the bed depth. There is an optimum bed depth at which the sifting rate is maximized. The sifting rate of a circular sieve is higher that of a rectangular sieve. The sifting capacity increases with the revolving speed.
