High-efficiency preparation system for waste concrete regenerated sand powder
The invention discloses a high-efficiency preparation system for waste concrete regenerated sand powder. The high-efficiency preparation system comprises a waste concrete sand-slurry crushing, stripping and sorting system, a regenerated sand directional grading regulation and control system; and a regenerated micro powder activation preparation system, the waste concrete sand-slurry crushing, stripping and sorting system produces regenerated sand and fine powder, the regenerated sand is supplied to the regenerated sand directional grading regulation and control system for grain grading directional blending, so that high-quality regenerated sand is produced, and the fine powder is supplied to the regenerated micro powder activation preparation system to be continuously ground, so that high-activity regenerated micro powder is produced. According to the high-efficiency preparation system for the waste concrete regenerated sand powder, components in the waste concrete sand powder are efficiently separated and prepared into the high-quality regenerated sand and the high-activity regenerated micro powder, and therefore natural river sand and mineral admixtures are replaced, the recycling level of waste concrete resources is improved, the resources are saved, the ecological environment is protected, and the major demand of national sustainable development is met.
本发明公开了一种废弃混凝土再生砂粉高效制备系统，本发明包括废弃混凝土砂‑浆粉碎、剥离、分选系统；再生砂定向级配调控系统；再生微粉活化制备系统。所述的废弃混凝土砂‑浆粉碎、剥离、分选系统生产再生砂和细粉；再生砂提供给所述的再生砂定向级配调控系统进行颗粒级配定向调配，生产高品质再生砂；细粉提供给所述的再生微粉活化制备系统继续粉磨，生产高活性再生微粉。本发明将废弃混凝土砂粉中各组分高效分离，并制备成高品质再生砂和高活性再生微粉，替代天然河砂和矿物掺合料，提高废弃混凝土资源的再生利用水平，既节约了资源，又保护了生态环境，是国家可持续发展的重大需求。
