METHOD OF CONVEYING GRAINY MATERIAL BY AEROCHUTE WITH INCLINED GAS-DISTRIBUTING GRID Russian patent published in 1995 - IPC

FIELD: transportation of materials. SUBSTANCE: method involves feeding gas flow at a rate of W_α ≅ W ≅ W_o/cosα , W_α- where is minimum allowable value of rate, at which conveyance of material is conducted, W_o is speed at the initial stage of fluidization process with aerochute inclination angle of α = 0; α^*- is angle of rest of grainy material; K₁, K₂ is permeability coefficient of grainy material. EFFECT: reduced specific power consumption and consumption of aerating gas, provision for usage of low-aerodynamic resistance grids. 1 dwg
