Embodiment

[0036] Embodiment: a kind of construction waste resource processing method, comprises the following steps:

[0037] (1) Manual selection: Classify construction waste by manual selection.

[0038] (2) Magnetic separation: pass the manually screened construction waste through a magnetic separator to remove metal materials in the material.

[0039] (3) Primary screening: the selected construction waste is screened into the first construction waste and the second construction waste with a sieve, wherein the particle size of the first construction waste is smaller than that of the second construction waste.

[0040] (4) Primary crushing: The second construction waste after primary screening enters the vibrating feeder through the silo; the second construction waste is sent into the crusher A through the vibrating feeder for crushing, until all the crushed The second construction waste passes through the first screen; wherein, the aperture of the first screen is smaller than or equ...

Description

technical field [0001] The invention relates to the field of construction waste transformation, and more specifically, it relates to a construction waste resource treatment method. Background technique [0002] With the acceleration of industrialization and urbanization, the construction industry has also grown rapidly, resulting in a large amount of construction waste. The vast majority of construction waste is disposed of in the suburbs or villages by landfill or dumping without treatment. These rubbish are mainly red bricks, reinforced concrete and their mixtures. Most of these construction wastes are transported directly to the outskirts or villages without treatment, and are disposed of in open-air stacking or landfilling, and stacking and landfilling require a lot of construction investment such as land acquisition and garbage removal. At the same time, Scattering and dust in the process of clearing, transporting and stacking have aggravated environmental pollution. ...
