The role of the beater in the air block production line is mainly to prevent the raw material from sinking in the pulping process. In the pulping process, due to continuous agitation, the viscosity of the slurry can be improved, its suspension performance can be improved, and the stability of pouring can be improved. There are a variety of specifications, the common is 10m, 20m, 50m and so on. The production principle of the beater is similar to that of the blender.
