Technical Field

[0001] The utility model relates to the technical field of solid waste cement treatment, in particular to a solid waste cement clinker calcining machine. Background Art

[0002] Cement is a powdery, hydraulic, inorganic cementitious material. After adding water and stirring, it becomes a slurry, which can harden in the air or in water, and can firmly bond materials such as sand and stone together. The early mixture of lime and volcanic ash is very similar to modern lime volcanic ash cement. It is used to bond concrete made of crushed stone. After hardening, it not only has high strength, but also can resist the erosion of fresh water or salt water. For a long time, it has been widely used as an important cementitious material in civil construction, water conservancy, national defense and other projects.

[0003] Solid waste cement needs to be calcined during its recycling. Currently, the solid waste cement calciner does not have a structure to crush the solid waste cement during use, which easily affects the calcination effect of the solid waste cement. Moreover, the flue gas during calcination of the solid waste cement calciner is directly discharged, and the waste heat of the flue gas cannot be recovered and utilized, which causes energy waste. Utility Model Content
