FY 1998 report on the results of the development in recycling technology for building materials such as waste concrete; 1998 nendo hai concrete nado kenzai recycle gijutsu no kaihatsu seika hokokusho

Abstract

For increasing fields of application of concrete rubble discharged as construction waste, the recycled aggregate is recovered by heating and rubbing/grinding. To meet the recycling demand effectively, a unit was made a transfer type. Equipment with treatment capacity of 3 tons/h was manufactured and confirmed of its motion. As to the heating equipment, the low-energy consumption structure aiming at homogeneous filling and appropriate ventilation was adopted to control uneven heating and increase in packed bed pressure loss. A tube mill type of the coarse aggregate recovery device was designed/manufactured considering the size of medium and discharge of mortal particles. An attriter type was designed/manufactured considering smooth particle discharge. As to the fine aggregate recovery system, a tube mill type was designed considering the discharge of powder and using coarse aggregate as medium. Moreover, the appropriate transportation of the generated powder and storage method are also considered. The transfer type equipment (unit frame, etc.) was designed/manufactured to make it a unit considered of layout at the time of transporting and assembling the auxiliary equipment such as supply hopper. The noise prevention device was also equipped with. (NEDO)
