Working principle of air conveying chute

Air conveying chute can be used for cement, fly ash and other easily fluidized powder materials. The tank uses a high-pressure centrifugal fan as a power source to keep the material in the closed conveying chute flowing slowly at the inclined end under fluidization, and the main part of the equipment has no transmission part. The new coated wheel breathable layer, sealing operation and management is convenient, the equipment is light in weight, low power consumption, large conveying force, easy to change the conveying direction.

If you don't know the raw material homogenization warehouse, you must watch it.

In the cement production process, in order to ensure the smooth progress of the production process, the loose materials. Such as: broken limestone, cement raw materials, cement clinker, different varieties of cement and mixed materials (fly ash, granulated blast furnace slag) for storage is necessary, and the storage capacity is also very large, for powdery loose materials. For example, cement raw materials, cement finished products, pulverized coal and pulverized slag are almost all stored in cylinder storage. Homogenization warehouse is a cylindrical single or multi-bin cylinder storage, large storage and circular storage. It has been proved to be effective in storing granular loose materials, clinker and crushed limestone, but also in storing powdery loose materials. such as cement, cement
