Classification & Storage / Dry unloading system
Dust-free discharging
Kopar’s dry unloading system assures an entirely automated, steady and dust-free unloading.
Fine-graded bulky materials are typically stored in feeding, intermediate, end or other silos.
From the silos, the granular material can be conveyed mechanically or pneumatically at the site or unloaded into trucks for transportation and usage at other destinations.
Most of the bulky materials stored in silos are dry and, thus, dusty. Due to health, safety, and environmental issues, their handling must be dust-free.
This is where our dry unloading system comes in handy.
The dry material is removed from the silo into a tank truck or a closed container with the Kopar dust-free unloading system for further transport of the material to another destination for later use.
A sealed system allows completely dust-free handling. Possible to carry out PLC or DCS automation.
Suitable usage cases of our dry unloading system
- All ashes – bottom ash, fly ash, filter ash, dusts
- Minerals like calcite, lime, magnesite
- Fine end products like potato starch
Technical specifications of the dry unloading system
Capacity (m3/h)
75-100
Operational Temperature (ambient)
-40/+40 °C
Travel length
1500 or 3600 mm
Designed for effortless use
Closed system design
Compared to our wet unloading system, dry unloading offers a closed solution to prevent any dusting.
The system typically consists of:
- fluidized silo bottom
- manual service slide gate
- pneumatic knife gate valve
- rotary feeder
- motor-driven flexible loading chute/loading spout/bellows
Easy & dust-free & safe
The entire dry unloading system is designed in-house at Kopar.
It is a fully automated and remotely operated stand-alone system that is designed to be used by the tank truck driver who can handle the filling operation with a remote control unit.
Dust removal from the bellows is diverted directly to the EMJET silo filter, in which case a separate filter in the loading spout is not needed.
Dust-free operation ensures the safety of the user.
Twin solution
It is rather typical to have both unloading devices, dry and wet, installed side by side.
Then either solution can be smoothly used depending which is most suitable in which occasion.
