AI Technical Summary
In existing technologies, cement clinker is not screened after crushing, resulting in a mixture of large, medium and small particles. This leads to excessively large gaps in the aggregate or compaction of small particles, resulting in low efficiency in cooling and waste heat recovery.
A pretreatment device for cooling and recovering waste heat of cement clinker was designed, including a box, crushing components, screen plates, mixing frames and conveying components. The crushed clinker is particle size distribution and mixing through screening and mixing components, and the particles are accurately mixed and stably discharged by a vibration unit and a discharge unit.
The particle size distribution was optimized, which improved the efficiency of subsequent cooling and waste heat recovery, avoided particle waste, ensured the formation of a suitable material layer, and improved the efficiency and quality of pretreatment.
