Special Silos

Special silos for recycling applications

KREYENBORG offers special silos for recycling applications for a wide range of materials with low and varying bulk densities:

Fiber Silo

Due to their relatively low bulk density, flow properties, consistency, or static electricity, light-weight materials such as fibers tend easily to bridge when being stored and discharged. The purpose of the Fiber Silo is precisely to avoid this unwanted effect.  

FaserSilo_20m-Ansicht3_HQ
Low bulk density specially for the processing of fibers with a low bulk density, also suitable for different flakes and powder
Bulk density 50 to 100 g/m³ (0,05 to 0,1 kg/dm³)
Agitator shaft the agitator feeds the material continuously towards the discharge screw
Material size fibers are 10 to 30 mm in length
Feeding from above via filling opening or tangential
Construction the conical design ensures a sloughing of the material and prevents bridging of the material
Outlet up to 3 controllable material outlets possible
Discharge consistent and adjustable discharge by means of a separate discharge screw
Manhole with limit switches for better maintenance of the silo
Volume 3 m³ to 50 m³
Materials standard or stainless steel
Railing/vertical ladder optional with guard rails on top and vertical ladder, including back protection
Options other options and sizes available on request

Film Flake Silo

Due to their relatively low bulk density, flow properties, consistency or static electricity, light-weight materials such as film flakes tend easily to bridge when being stored and discharged. The purpose of the Film Flake Silo is precisely to avoid this unwanted effect.  

Folien_Silo
Low bulk density specially for the processing of film flakes with low bulk density
Bulk density 20 to 300 g/m³ (0,02 to 0,3 kg/dm³)
Mixing screw three vertically-mounted mixing screws
Homogenization constant movement of the material promotes homogenization of film flakes of variable thickness and size
Material size film flakes are up to 30 mm in length
Feeding tangential feeding
No dead zones specially shaped silo to avoid dead spots
Discharge consistent and adjustable discharge via a separate discharge screw
Manhole with limit switches for better maintenance of the silo
Volume 3 m³ to 40 m³
Materials standard or stainless steel
Railing/vertical ladder optional with guard rails on top and vertical ladder, including back protection
Options other options and sizes available on request

Block-Type Silo

Special Block-Type Silo for the storage and dosed discharge of ground and sensitive materials such as film shreds, fibers, foams, etc.

Bunker_Silo
Low bulk density specially for the processing of materials with low bulk density
Sensitive bulk especially suitable for sensitive bulk
Bulk density 50 to 200 g/m³ (0,05 to 0,2 kg/dm³)
Feeding tangential feeding by means of pressure transport
Loosening the bottom of the structure contains a twin discharge screw and stepped loosening elements that prevent the material from bridging
Discharge The material sinks smoothly. A trough screw extended over the complete length of the silo ensures an uniform and adjustable discharge.
Manhole with limit switches for better maintenance of the silo
Volume by default, block-type silos with a volume up to 60 m³ are available
Materials standard or stainless steel
Railing/vertical ladder optional with guard rails on top and vertical ladder, including back protection
Options other options and sizes available on request

Stock Silo

Stock silos are used for interim storage of sophisticated and high-quality bulk materials, such as pellets, raw materials or powders. We offer silo diameters of up to 2,850 mm as standard, but we are also happy to implement other diameters for our customers.  

Products plastics, raw materials, pellets, agglomerates, flakes, powders, regrinds, cut/ground goods
Feeding tangential feeding via pressure transport
Manhole with limit switches for better maintenance of the silo
Volume on request
Materials aluminium, normal or stainless steel
Railing/vertical ladder optional with guard rails on top and vertical ladder, including back protection
Options other options and sizes available on request
