The production of the ceramsite by using the solid wastes is the mainstream direction of the ceramsite production at present and is one of the important means for the resource utilization of the solid wastes. A part of solid waste ceramsite such as fly ash ceramsite, sludge ceramsite, coal gangue ceramsite and the like is produced on a large scale, and gradually replaces natural resource ceramsite such as clay ceramsite, shale ceramsite and the like, and becomes the mainstream of the ceramsite market. However, as the research on solid waste ceramsite is further and further developed, more and more solid waste is used for preparing ceramsite, and the ceramsite is prepared by mixing and burning various solid wastes due to various solid wastes with various types, various components and different natures. Most experimental researches are carried out in a box furnace or a tubular resistance furnace, which is greatly different from large-scale production conditions and limits the industrialization of experimental results. On the other hand, from the perspective of talent training, the training of engineering practice ability and innovation ability of students is more and more urgent for higher education and national science and technology development, and at present, hardware for engineering training and production training of students is very deficient. Therefore, the pilot production line of the ceramsite is very necessary for research and talent culture.
At present, a few of ceramsite pilot-scale test production lines are mostly in enterprises, and the ceramsite pilot-scale test production lines are high in production capacity, high in operation cost, strong in raw material pertinence and not suitable for flexible and changeable experimental conditions and practical teaching. Recently, some colleges and scientific research institutions build small-scale ceramsite pilot-scale production lines in schools or institutions, such as Shandong university, Xian wall material research and design institute Co., Ltd, Tianjin cement industry design research institute Co., Ltd and the like, but the production lines are difficult to achieve continuity and integrity due to the limitation of sites and other conditions, only the discontinuous combination of a rotary kiln, a stirrer, a granulator and other host equipment is needed, and the adjustment and control of process parameters are different from the actual production. Therefore, it is necessary to provide a special arrangement process for establishing a pilot-scale continuous production line of solid waste ceramsite in a limited space of a school or a scientific research institution.
