Classified according to the movement form of the main air flow in the calciner

According to the movement form of the main air flow in the furnace, there are four basic types of calciner: swirl type, spray type, suspension type and fluidized bed type. In these four types of calciners, raw materials and fuels are dispersed in the airflow by "swirl effect", "spray effect", "suspension effect" and "fluidization effect" respectively.What needs to be done for heat treatment with vacuum oil quenching furnace? Most of the calciners developed in the early stage mainly rely on one
