This Astec lime silo (500BBL ±) The weigh pod is suspended by three load cells and includes aeration pads There is a high and low bin indicator and fill lin The structure of the silo is solid but it is slightly dented on one side The unit was vented directly to the plant bag house This unit was taken down when the new plant was installed
Sodimate silo discharge uses gentle agitation, rather than vibration or fluidization, when discharging and feeding the dry powder Vibrators mounted directly.
There are two basic types of feeders used in industrial plants: volumetric and gravimetric As its name implies, a volumetric feeder modulates and controls the volumetric rate of discharge from a bin (eg, cu ft/hr) The four most common types of such feeders are screw, belt, rotary valve, and vibrating pan A gravimetric feeder, on the .
