In the context of "zero waste city" construction, construction waste treatment is a key disposal area. Because my country's urbanization process has been rapid in recent years, the amount of construction waste generated has increased year by year, accounting for about 40% of domestic waste. If it is not properly handled, it will seriously affect the ecological environment and is a waste of resources. With the introduction of the national "zero waste city" construction plan, various provinces and cities have also successively introduced local "zero waste city" construction work plans. In terms of construction waste resource treatment, most of them require that the construction waste resource capacity should reach 70-80% by 2025.

Construction waste is complex in composition, containing not only a large amount of concrete bricks and stones, but also a large amount of debris. Therefore, in the process of construction and decoration waste treatment, it is very important to remove the debris. Only by removing the debris can we get pure aggregates for use in recycled building materials. Today we will introduce the key equipment for dealing with debris - screening equipment.

Let’s first take a look at which screening equipment will be used in the construction waste treatment production line. There are rod screens, circular vibration screens, multiple frequency screens, bouncing screens, tension and relaxation screens, etc. You can clearly understand them just by listening to the names.

These screens have different uses. For example, bar screens are mainly used to screen out concrete blocks and large light materials at the front end; circular vibrating screens are usually used as finished product screens to screen out aggregates of different specifications for different applications at the back end; multi-frequency screens, bouncing screens and tension and relaxation screens are also used to screen out debris or grade finished products at different stages. How to choose different screening equipment depends first on the composition of construction and decoration waste. Different compositions will require different screening equipment at different stages, and secondly, it depends on the demand for aggregates at the back end.

In short, the treatment of construction and decoration waste, impurity removal is very important, the application of various screening equipment is also to separate the debris, get purer aggregate, improve the resource utilization rate of construction and decoration waste. Construction and decoration waste resource equipment is very important from equipment quality to production line design and planning, must be compared and investigated to select the appropriate process route and equipment manufacturer.
