Method for preparing recycled concrete from waste concrete
The invention discloses a method for preparing recycled concrete from waste concrete. The preparation method comprises the following steps: 1, waste concrete is crushed and recycled: the waste concrete is pulled to a special crushing and recycling site; firstly, a hammer crusher is used for carrying out primary crushing treatment on waste concrete stones, the preliminarily crushed small concrete blocks are put into a tooth roller type crusher for secondary damage treatment; in the crushing process, the crushed large non-orthopaedic waste materials are sorted out, and small metal fragments in the waste materials are adsorbed and removed through an electromagnet; 2, dust falling, screening and classifying treatment is conducted: a, a special pool for dust falling and screening is built in the crushing field, in the process of treating waste concrete, a water immersion type screening operation mode is adopted, screening operation can be conducted in water, dust in the screening process isblended into water, and therefore the possibility that the dust enters air is reduced, and the purpose of environmental protection is improved.
本发明一种利用废弃混凝土制备再生混凝土的方法，其步骤如下：步骤一，废弃混凝土破碎回收处理：将废弃混凝土拉至专门的破碎回收场地，首先通过锤式破碎机对废弃混凝土石块进行初步破碎处理，将初步破碎完成的混凝土小块放置入齿辊式破碎机内进行二次破损处理，在破碎的过程中将破碎出来的大块非骨科类废料分拣出来并通过电磁铁将内部的金属小型碎块吸附排除，步骤二，降尘筛选分类处理：a.在破碎场地内建设有专门的降尘筛选用水池，在对废弃混凝土进行处理的过程中，采用浸水式的筛选操作的方式，可以在水中进行筛选作业，使得筛选过程中的灰尘融入到水中，从而减少了灰尘进入到空气中的可能性，提高环保的目的。
