<p><P>PROBLEM TO BE SOLVED: To produce high newton dehydrated cake by water expulsion promptly after car washing by separating the admixture and aggregate contained in the sand-containing sludge of a ready-mixed concrete factory and promptly invalidating the effect of the chemicals. <P>SOLUTION: Sludge water is brought into collision against an impact plate by using the energy of a pump. At this time, air is fed and the sludge is agitated by an agitator to thereby attenuate the effect of the admixture, to wash the fine aggregate and to separate the chemicals and the fine aggregate. The froth by the oxidation of the admixture is invalidated by cutting and pulverizing. As a result, the clean sand is made. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
