Problems solved by technology
With the development of urbanization, the discharge of construction waste in engineering construction is increasing year by year, and its recycling work is progressing slowly, resulting in a low utilization rate. At present, the rough landfill treatment occupies a large amount of land resources. It not only wastes manpower and material resources to maintain the discharge site, but also has an impact on vegetation and groundwater, leading to secondary pollution of the environment

Abstract
The invention discloses a production process of a construction waste recycled aggregate, and the production process comprises the following steps: removing impurities, to be more specific, firstly, removing impurities in a construction waste by an impurity removal device; drying, to be more specific, drying the decontaminated construction waste through a dehumidifying device to ensure that the humidity is 14% or less; performing fine grinding, to be more specific, using a ball mill for fine grinding of the dried construction waste to obtain fine powder; screening, to be more specific, using a screening device for screening of fine powder to screen out recycled powder with the particle size less than 0.15mm; and drying and bagging, to be more specific, the screened recycled powder is dried again, and finally bagged to obtain the construction waste recycled aggregate. The production process can be used to effectively deal with the construction waste to prepare recycled bone meal, is eco-friendly, can improve the recycling effect of the waste, can maximize the use of resources, and beautifies the living environment, meanwhile, by use of the impurity removal device, the dehumidifying device, the ball mill, the screening device and an automatic packaging machine, improvement of the production efficiency of conversion of the construction waste into the recycled bone meal is facilitated, and the production process is convenient and quick.
Description
technical field [0001] The invention relates to the field of construction, in particular to a production process of recycled aggregate from construction waste. Background technique [0002] Construction waste refers to the construction units, construction units newly built, rebuilt, expanded and demolished various buildings, structures, pipe networks, etc., as well as the spoils, materials and other wastes generated during the process of residential decoration and house decoration. With the development of urbanization, the discharge of construction waste in engineering construction is increasing year by year, and its recycling work is progressing slowly, resulting in a low utilization rate. At present, the rough landfill treatment occupies a large amount of land resources. It not only wastes manpower and material resources to maintain the discharge site, but also has an impact on vegetation and groundwater, leading to secondary pollution of the environment. Therefore, how t...
