METHOD FOR RECLAIMING AGGREGATE FROM SCRAPPED CONSTRUCTION MATERIALS AND RECLAIMING APPARATUS THEREOF

摘要

The present invention increases the efficiency of the process after a pre-screen process not based screening the waste concrete collected from construction waste, not linear crushing process through the parallelized crushing process and, in a straight line crushing process in accordance with the repeated crushing of the aggregate using construction waste to prevent degradation and energy waste relates to the aggregate playback method and playback device.; To this end, the present invention is to exceed, and less to the primary screen the waste concrete particles ground to a particle size of less than 40㎜ from construction waste in the first oscillation selector, based on the selected reference value selected from the range of the reproduction fine aggregate a first step of selecting a range and; Among the selected particles in the first step particles which is greater than the selected reference value is a second step of pulverizing by introducing a pulverizer, respectively; And a third step of the second screen, the milled particle in the second step to the second vibration screening sorting based on the range of the selected reference value and / or reproducing coarse aggregate; Is selected in the third step the particles is greater than the selected reference value is a particle of said selected reference value or less, and fed back to the first stage is input portion cyclone differential absorption with particles of less than the selected reference value selected in the first step by supplying the air discharged from the cyclone back to the supply air of the non-distributed jipbu provides an aggregate reproducing method and reproducing apparatus using the construction waste, characterized in that it comprises a fourth step of selecting a reproduction fine aggregate and pulverized.
