There are four basic forms of air flow in the calciner: vortex, eruption, suspension and fluidized bed. In these four types of calciners, raw materials and fuels are dispersed in the airflow by "vortex effect", "spray effect", "suspension effect" and "fluidization effect" respectively. CS SERIES SCISSOR TYPE METAL CUTTING SAW CS-220 Due to the relative movement between the materials in the flow field in the furnace, it can achieve high dispersion, uniform mixing and distribution, rapid heat exchange, prolong the residence time of materials in the furnace, and improve the combustion efficiency, heat exchange efficiency and carbonation of the materials entering the kiln. The purpose of calcium breakdown rate.CS SERIES SCISSOR TYPE METAL CUTTING SAW CS-280II Most of the calciners developed in the early stage mainly rely on one of the above four effects. In recent years, with the development and maturity of pre-calcining technology, various types of calciners have interpenetrated technically, Vacuum brazing of surgical forceps - heat treatment process and most of the new calciners tend to adopt the "comprehensive effect" of the above effects to further improve performance and improve operating efficiency. Its development mainly includes the following aspects.Aluminum alloy micro-channel cooling plate vacuum gas quenching
