Cement concrete slab in-situ cement regeneration process
The invention discloses a cement concrete slab in-situ cement regeneration process. The process comprises the steps of crushing, sorting, filtering, precipitating and drying. A whole concrete slab is subjected to crushing, iron removal and screening, so that fine sand in the waste whole concrete slab is recycled and reused, and the use of the fine sand is reduced. The on-site recycling mode is adopted, so that the cement concrete slab transportation cost is reduced, and concrete slab recycling is more widely used; and the stirring recycling mode is adopted, so that a wet type permanent magnet drum type magnetic separator can conveniently recycle scrap iron in slurry and remove the scrap iron on site.
本发明公开了水泥混凝土板就地水泥再生工艺，所述工艺包括破碎、分选、过滤和沉淀干燥的步骤，将整块的混凝土板进行破碎除铁以及筛分，使得废弃的整块混凝土板中的细沙受到回收再利用，减少细沙的使用。本发明中，采用现场回收循环使用的方式，以减少水泥混凝土板运输的成本，使得混凝土板回收受到更广泛的使用，采用搅拌回收方式，以便于湿式永磁筒式磁选机对于泥浆中的铁屑进行回收，以及现场除铁屑使用。
