PARTICLE DIAMETER SORTING DEVICE FOR DIFFERENT DIAMETER PARTICLE MIXTURE CONTAINING CLAYEY PARTICLE AND METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To simplify structure by optimizing the particle diameter distribution of a different diameter particle mixture containing a clayey particle in place of washing. ;SOLUTION: The method is conducted by obliquely discharging the different diameter particle mixture containing the clayey particle from a belt conveyer 1 by giving and obliquely discharging angle to the vertical direction. The obliquely discharged mixture receives the wind pressure different by particle diameter and falls down to each falling spot after a flying time different by particle diameter. The particle diameter of the single particle falling down between specified 2 spots distributes desirably between 70 μm to 2.7 mm. One having the distribution is used as a concrete material.;COPYRIGHT: (C)1999,JPO
