Problems solved by technology

[0002] In the existing construction waste resource disposal methods, the classification and removal of impurities with different particle sizes is usually sorted manually, which makes manual sorting unable to sort out some fine impurities (such as dregs)
It can be seen that the impurity content of the dregs in the existing disposal results is usually high, which will affect the subsequent use, and even require secondary consumption, causing environmental pollution and is not conducive to the resource utilization of construction waste

Abstract

The embodiment of the present application provides a construction waste resource disposal method and equipment, which relate to the field of construction waste resource classification, and the method is applied to construction waste resource disposal equipment including coarse crushing device, heavy screening device and fine screening device , including: when construction waste is detected, coarsely crush the construction waste through a coarse crushing device to obtain coarsely crushed materials; The material on the first sieve and the material under the first sieve; when the material under the first sieve is detected, the particle size of the material under the first sieve is screened by a fine screening device to obtain the material on the second sieve and the material under the second sieve Materials; wherein, the second under-sieve material is slag after impurity removal. It can be seen that the implementation of this embodiment can effectively remove fine substances such as muck and soil, avoid secondary consumption, prevent environmental pollution, and facilitate the resource utilization of construction waste.

Description

technical field [0001] The present application relates to the field of recycling and classification of construction waste, in particular, to a method and equipment for recycling construction waste. Background technique [0002] In the existing construction waste recycling method, the classification and removal of impurities for materials with different particle sizes are usually manually sorted, which makes it impossible to sort out some fine impurities (such as dregs) by manual sorting. It can be seen that in the existing disposal results, the impurity content of the slag is usually high, which will affect the subsequent use, and even require secondary consumption, causing environmental pollution, which is not conducive to the resource utilization of construction waste. SUMMARY OF THE INVENTION [0003] The purpose of the present application is to provide a construction waste recycling method and equipment, which can effectively remove small substances such as dregs, avoi...
