Abstract

The invention discloses a method for recycling construction wastes. The method comprises the following steps: artificial sorting, vibratory sorting, primary crushing, iron removing, secondary crushing and sorting through a vibrating screen. According to the method for recycling the construction wastes, steps are reasonable and orderly, selected equipment is advanced, and the running cost is low. By the method, the sorting efficiency is high, a large quantity of recycled aggregates which are good in quality and are fine-grained can be produced, and the recycled aggregates which are produced by the method do not contain other impurities, and belong to high-quality recycled materials. Meanwhile, residue soil, scrap iron, clothes, wood blocks, plastics, micro-powder and the like in the construction wastes can further be recycled and are fully utilized, the construction wastes are sorted thoroughly, the utilization rate of raw materials is high, and therefore, the method has high benefit of environmental protection and marketization popularization prospect.

Description

technical field [0001] The invention relates to the technical field of garbage collection, in particular to a method for recycling and reusing construction garbage. Background technique [0002] Construction waste is a general term for muck, waste concrete, waste masonry and other wastes generated during demolition, construction, decoration, repair and other construction production activities. Since construction waste has the characteristics of being resource-based, land-occupied and harmful to the environment, how to realize resource utilization of construction waste is of great significance for resource conservation, environmental protection and sustainable development of the construction industry. In the prior art, regarding the recovery of construction waste, there are problems such as insufficient recovery process, backward equipment, and high operating costs. The above problems directly lead to incomplete sorting of construction waste, low utilization rate of raw mater...
