Silos for powders and granulates
Are you looking for a silo that completely empties without leaving any residue? Our rotationally moulded conical tanks made of MDPE or linear polyethylene are perfectly suited for the storage, processing, and dosing of powders and granulates (such as sugar, flour, cocoa powder, milk powder, grain, or feed).
Thanks to the conical bottom, the tank fully drains, preventing valuable material from being left behind.
Why choose a silo from CGK?
- Complete drainage without residue
- Durable and cost-effective
- Available in various volumes (from 330 litres)
- Mirror-smooth tank walls for optimal product flow
- Lightweight and easy to handle
- Certified for food safety (FDA-certified)

- Constructed according to the strictest building codes
- Fast delivery and available in custom designs
Accessories
Our silos can be equipped with a variety of accessories tailored to your specific application.
Drainage options
- Outlet diameters of 200 mm, 350 mm, or 450 mm
- For smaller tanks: from 2”
- Guillotine valve, butterfly valve, or diaphragm valve (in aluminium or stainless steel)
Customisable frames
- Available in painted, galvanised, or stainless steel
- U-profile base for easy lifting and moving with a forklift
- Elevated frames available (to raise the tank up to 1800 mm)
- Options with fixed or swivel wheels for added mobility
- Stackable versions for efficient storage
Additional closures and ventilation
- Removable screw lid with ventilation opening
Wall thickness
- Adjustable depending on the powder’s density
Agitator
For products that tend to clump quickly or require constant mixing, an agitator can be added. This is ideal for the food industry (e.g. flour or sugar blends), but also for chemical applications where solids need to remain homogeneously mixed.
Do you have specific requirements?
Customisation is possible to ensure the silo fits perfectly into your production process.
Take a look at our tailor-made storage, mixing, and process tanks to find the ideal solution for your needs.
