Find where the flow actually stops
Compare the requested feed with the actual discharge. Record whether the problem occurs after storage, when starting, at low level or throughout operation. Confirm the outlet valve position and that the receiving screw, weigh hopper or process is ready. A full downstream vessel can stop transfer even when the silo material flows normally.
Choose the aid by its working principle
- Aeration pads or nozzles: introduce air locally into suitable powders. Air quality, material behaviour and the available venting path must be considered together.
- Bin activator: moves the discharge assembly using controlled vibration. The cone connection, suspension and connected equipment must accommodate that movement.
- Outlet valve: opens or closes the route; it cannot reliably break an obstruction higher in the silo.
More air or stronger vibration is not automatically better. First establish whether the powder is compacted, moist, cohesive or being held back downstream.
Make the whole discharge sequence work
The receiving equipment must be able to accept material before discharge begins. Define level permissives, valve position feedback and the sequence for starting and stopping the flow aid and feeder. If the feeder trips, continued silo discharge can overload the receiving hopper.
A bin activator and a dosing feeder are complementary: making material available at the outlet does not by itself establish the mass delivered to a recipe.
What changes between sectors
For cement and minerals, discuss abrasion and storage time. In food and feed, include cleaning, contamination control and moisture. For chemicals and plastic powders, provide compatibility and dust-hazard data. The same symptom does not justify the same equipment execution in every sector.

Information that makes a selection possible
Provide cone angle, outlet diameter, material and bulk density, storage duration, discharge rate and a photo of everything below the cone. Include the present flow aid, air supply data and the point where interruptions occur. Internal examination requires isolation and the site’s confined-space arrangements; do not enter a silo or strike its shell to release material.
Send the material data and a photograph or layout of the installation so we can define the equipment and connection requirements.
Use the bridging and ratholing guide when the observed flow pattern suggests a blockage or a flow channel inside the stored material. The silo is full—why has material stopped flowing?.
