For your consideration, we offer here a simple comparison of the two silo types. We think the case for horizontal is stronger and well worth considering even though the capital cost is higher.
20 Tonnes capacity horizontal cement silo mounted on load cells.
Typical Load Cell Mounting Detail
Pros:
Looks like a standard HQ container and can be transported on a container truck.
Low profile helps the visual look of the site and makes it safer for roof access
Load cell mounting provides real time weight based measurement of its contents and can be integrated into existing systems
Aeration and vibration ensures the product settles into the integrally built discharge screw conveyor
Easy to install, lower installation cost and requires only a Franna with spreader bars to position it
Can be located anywhere close to the batch plant and does not need heavy foundations
Easy to maintain and reach the accessories
Needs no special council permissions as it can be easily re-located
Cons: - yes, there are always these but, in this case, there is only one!
The capital cost is higher than a bolted silo
Typical 55 tonnes capacity vertical bolted silo
Pros:
Segmented manufacture
Bolted construction
Transportable in a 20’ container
Can be assembled with unskilled labour
Lower capital cost than a horizontal silo
Cons:
There are a few of these!
Many components to assemble = longer time = more money
Care needed when assembling the wall segments to make sure all joints are tight with the rubber gaskets supplied.
Any leaky joints and water will seep into the cement
Many Boxes of bolts and nuts – enough to drive one “nuts”
Visually intrusive
Requires a large foundation to withstand wind loads
Will need council approval due to its size.
