The chemical unit 1000 can complete all processing procedures by cleaning, printing, pre-curing, throwing and deep curing the materials in sequence, realizing continuous and automatic processing of each process flow without the need for human participation and work, which greatly improves production efficiency and stability. After the processing is completed, the unloading unit automatically unloads, transfers and finally transfers the materials to the clinker bin 1100 to complete the clinker collection. The entire production line has a high degree of automation and stability, which can significantly improve production efficiency. In actual production applications, this production line can increase its production capacity from 900pcs / H to 3500pcs / H.
