Abstract
Description
Technical Field
[0001] The utility model relates to the field of construction engineering, and more particularly to a device for classifying and recycling construction engineering waste. Background Art
[0002] During the construction process, a large amount of building materials, such as concrete and steel, are used. In the process of building, a large amount of construction waste is often generated. Construction waste can only be used after recycling. Therefore, it is necessary to use garbage sorting and recycling equipment to sort and recycle construction waste. In the process of concrete recycling, according to recycling requirements, it is often necessary to crush the concrete into a fixed particle size to facilitate the transportation of recycled materials. Existing sorting and recycling devices can generally only screen concrete materials according to volume size. There may be metal materials in the concrete of some abandoned structures. If the concrete is only screened according to volume size, the metal materials cannot be separated from the concrete, which affects the recycling of the metal materials. At the same time, the existing sorting and recycling structure only crushes the material once during the recycling process of concrete materials. The crushed concrete may not meet the screening requirements and the metal materials cannot be completely separated from the concrete, resulting in waste of metal materials and increased costs.
