Description

Technical Field

[0001] The utility model relates to the technical field of solid waste grading, in particular to a cement-added solid waste grading device. Background Art

[0002] The composition of construction waste is relatively similar to that of mixed materials such as fly ash and granulated blast furnace slag. Abandoned construction waste inevitably contains some unhydrated particles. These particles cannot be hydrated due to their large particle size, but after they are ground into fine particles again, they will regain their previously unused hydration activity. The use of construction waste can greatly reduce the exploitation of natural resources and reduce the amount of garbage discharged into the nature, thereby achieving the reduction of construction waste, resource utilization, conservation of natural resources, and protection of the ecological environment.

[0003] Resources are utilized by adding construction solid waste into cement admixtures. Most of the crushed solid waste is directly added to cement. There are some large particles in the solid waste, which will affect the quality of cement, so grading is required.
