|Storage Silo Innovative Batcher|
Astec's innovative batcher helps eliminate mix segregation. It is designed to ensure that the quality of mix that leaves the drum is the same quality stored in the silos.
Fill Silos Without Segregating the Mix
The mix moves by drag conveyor or bucket elevator into a three-ton batcher atop the silo. When full, the batcher releases the slug of mix. Mix drops through the rapid-opening clam gate into the silo and flattens on impact. Batchers with a single radial-type gate can off-center the drop. Our batcher clam gates center the drop into the silo and form a flattened mix surface, which prevents mix segregation.
Automatic Batcher Gates
The precisely activated batcher gates operate automatically. When the batcher is full the cylinder-operated clam gate opens. Mix discharges in bulk, and the gate closes just before the batcher is completely emptied. This way mix always collects in the batcher first and never falls straight from the drag conveyor into the silo. Sensors control the proper opening and closing of the batcher.
Keep Silo Pressure Equalized
As the mix level rises, it displaces air in the silo. Vents in the batcher enclosure allow this air to escape and keep pressure in the silo equalized.
Bin Indicators Show Mix Level in Silos
Each Astec silo has a high and a low radio-frequency bin indicator. Mounted on top of the silo, the sensing rods extend down into the mix. The low bin indicator reaches deep into the silo; the high bin indicator is short. Both the high and low bin indicator information is transmitted to the control house so that personnel can track mix level. The high bin level indicator signal allows the operator sufficient time to finish loading mix already in the transfer conveyor, while the low signal informs the operator to begin filling the silo before the cone surface liners become exposed.
