Abstract

PURPOSE:To enable the reutilization of cement resources by reduced energy, by concentrating sludge water from which gravel and sand are removed by set classification and finely pulverizing the conc. one according to a wet vibration system. CONSTITUTION:Washing water 14 from a mixermobile for ready-mixed concrete is supplied to a classifier 10 to be classified into gravel G, sand S and sludge water H corresponding to a particle size by a wet system. The classified sludge water H is recovered in a recovery tank 21 and sent to a sludge water tank 24 by a pump 22 through a cyclone 23 and, when reaches a predetermined amount under stirring, sent to a thickener 20 by a pump 25. The forcible sedimentation of a sludge component by each stirrer and the return of supernatant water are performed until the sludge water reaches a concn. adjusting tank 30 from the thickener 20 and the concn. sludge water finally adjusted so as to set the concn. of sludge to 30-40% is sent to a vibration ball mill 40 where a fine cement anhydride is taken out from the sludge water finely pulverized under vibration.
