Background
Gypsum is a common building material commonly used for surface finishing of interior walls and ceilings. During construction, the finished plaster of paris is typically stored in a silo in the form of powder or granules. However, in the construction process, since gypsum materials are often agglomerated or compacted due to long-time storage or transportation, the fluidity of powder is weakened, and breakage is likely to occur when the gypsum materials enter the conveying reamer from the bin, and in order to restore the gypsum materials to a loose state, a material loosening treatment may be performed using compressed air. The traditional solution is to install the air distribution plate at the cone of the cone bin, and to loosen the materials by inputting compressed air into the bin, but the air distribution plate is blocked and cannot work normally due to the fact that a large amount of water is contained in the pure compressed air.
