Flow Promotion Aids Manufactured by INDPRO Engineers, Indore
The task of choosing a flow aid for a particular problem and knowing whether or not the device will work is more often accomplished by relying on experience or through trial-and-error, rather than the application of science and engineering. However, with knowledge of how solids flow through storage bins and other equipment, and an understanding of the properties of bulk materials that give rise to flow problems, selection and use of flow aids can be accomplished with a much higher level of confidence. There are many reasons for powdered or granular materials not discharging from hoppers or silos. Material converging towards the outlet of a hopper builds up forces within itself, which can cause it to become self-supporting. Particle size, particle shape, material bulk density, moisture content and hopper design are some of the factors which determine whether or not a product will bridge, rat-hole or segregate upon discharge.
