The new air permeable layer is suitable for pneumatic conveying device of powder, granular material, cement, alumina and so on, but also suitable for pneumatic conveying device of other powder and granular material, such as train, It is used as gasification bed to mix the material with air in gasification state and has good fluidity in order to improve transportation efficiency. If used in cement raw meal homogenization storage, cement raw material can be stirred evenly.

The pneumatic conveyer and gasification bed device have been widely used in metallurgy, building materials, chemical industry, power plant, food and transportation industry. The equipment is not damaged by friction, and the maintenance quantity of the equipment is reduced. At the same time, the material is transported in the closed chute, which ensures that the bad condition is not polluted.
