Gravimetric and Volumetric Feeding of Particulate Solids

Jan 01, 2016· Two types of flow patterns can occur when a bulk solid is discharged from a hopper, bin or silo: A typical funnel flow pattern is shown on the left, and a mass flow pattern is shown on the right By contrast, in funnel flow, an active flow channel forms above the outlet, but stagnant material remains (called ratholes) at the periphery of the vessel.

Single screw feeders are also an option when configured correctly. Without consistent, dependable feeder accuracy and repeatability for your process, the integrity of any recipe — and hence the final product — will be compromised. This will directly impact the system reliability, product yield and economic performance of the overall operation.

Can you go with the flow? Solids flowmeters for industrial ...

When a feeder stops, solids flow should cease. When a feeder is turned on, there should be a close correlation between its speed of operation and the rate of discharge of the bulk solid. Feeders differ from conveyors in that the latter are only capable of transporting material, not modulating the rate of flow. Dischargers are also not feeders.
