Description

Technical Field

[0001] The invention belongs to the technical field of construction waste separation, and in particular relates to a construction waste separation structure and a separation construction method thereof. Background Art

[0002] With the development of society, people have paid more and more attention to environmental protection, and waste recycling is one of the most common environmental protection means. When dismantling old buildings, a large amount of construction waste will be generated. After crushing, mixing, screening and other processes, these wastes will form smaller sand and gravel. After cleaning and screening, the sand and gravel will be obtained as finished sand particles, which can be reused as raw materials for construction, etc. However, construction waste is large and small. For larger waste, a crushing structure with a larger gap is required when crushing, and a crushing structure with a smaller gap is required for smaller waste. If a larger gap crushing structure is uniformly adopted, the smaller structure of waste cannot be crushed well. If a smaller gap crushing structure is uniformly adopted, the crushing efficiency of the larger structure of waste is very low. Therefore, it is necessary to carry out targeted crushing for waste of different volumes. Summary of the invention
