Mixers/ Silos

KREYENBORG offers multiple mixers and silos for various recycling operations. These components can be retrofitted to pre-existing systems or included in new systems.

Mixers

Kreyenborg Universal Quick Mixer/Silos USM Type - eFACTOR3

USM

The stable and easy to operate Universal Quick Mixer USM type is used wherever pourable bulk materials must be quickly and economically mixed.

ApplicationPrecise blending of bulk materials.
ProductsFor example: granules, masterbatch, compounds, agglomerates, powder, flakes, cut / ground freight.
FormThe USM consists essentially of a cylindrical container with a cone and a centrally-oriented mixing screw.
Mixing screwMixing screw is located in a mixing tube
FunctionThe product is taken up by the mixing screw and is conveyed upwards through the mixing tube. At the top of the screw an ejector (distributes) casts the material downward, spreading it finely throughout the mixing bin.
FeedingThe mixer can be fed either through a filling device at the top or by the optional lower feed hopper.
MaintenanceThe mixer is entirely accessible through a large cover flap and manholes in the cylinder and the cone. Since there are no dead areas, the machine can be quickly and thoroughly cleaned, then used with other products.
EmptyingEmptying can be adjusted to various aggregates, and to individual units.
Cylinder Ø 25 in to 110 in (600 mm to 2,850 mm)
Height with direct drive70 in. to 395 in. (1,800 mm to 10,100 mm.)
VolumeVolumes from 35 ft³ to 1,410 ft³ (Volumes from 1 m³ to 40 m³)
StartMixer starts working even when filled. Interval-like flow possible.
Quiet operationRuns almost noiselessly.
No DustNo dust formation around the mixer during mixing operation.
DemixingNo demixing, even with long running times.
EmptyingMaterial can be diverted into a cone chute.
CleaningCan be accessed for cleaning through the large cover flap, as well as through manholes in the cylinder and cone.
StorageSpecially designed bearings with optimal seals.
StableA solidly constructed mixer. “Made in Germany”.
EconomicalShort mixing times and low energy consumption.

SFM

The stable and easy-to-operate SFM mixer is specially designed for light and sensitive solids, developed and used for products that need to be quickly and thoroughly, but gently mixed. It makes for optimal homogenization of products. The SFM also allows for quick and easy cleaning.

Stable and Easy-to-operate SFM Mixer/Silos - designed for light and sensitive solids
ApplicationPrecise, gentle and holistic blending of bulk materials which must be continuously and thoroughly mixed, or which tend to bridge.
ProductsFor example: granules, masterbatch, compounds, agglomerates, powder, flakes, cut / ground freight.
FormThe SFM consists essentially of a cylindrical container with a cone and a spiral, close-clearance mixing screw.
Mixing screwMixing screw spiraling and close-clearance mixing screw.
FunctionThe product is mixed homogeneously and permanently by the spiral and close-clearance mixing screw. No dead zones in the container.
FeedingThe mixer can be filled in various ways, for example, from above via a nozzle or through a side hopper.
MaintenanceThe mixer is entirely accessible through a large cover flap and manholes in the cylinder and the cone. Since there are no dead areas, the machine can be quickly and thoroughly cleaned, then used with other products.

Kreyenborg Quick Mixer/Silos MBM Type - eFACTOR3

MBM

The stable and easy to operate Quick Mixer MBM type is specifically designed for sensitive bulk materials and is used where products need to be handled gently and quickly mixed. It makes for an optimal homogenization of products. The MBM allows a quick and easy cleaning.

ApplicationGentle and rapid mixing of bulk materials.
ProductsFor example: granules, masterbatch, compounds, agglomerates, powder, flakes, cut / ground freight.
FormThe Quick Mixer MBM type based on the well-proven principle of a vertical, centrally arranged screw.
Mixing screwMixing screw stay free inside the mixer.
FunctionThe product is continuously and gently mixed by mixing screw and it makes for a optimal homogenization of products.
FeedingThe mixer can be fed in various ways, for example, through a filling device at the top or by the optional lower feed hopper.
EmptyingThe outlet pipe, which is located centrally below the cone, provides a very good emptying of residual material.
MaintenanceAll places inside the mixer are freely accessible through a large cover flap and manholes in the cylinder and the cone. There are no dead areas, so the machine can be quickly and effectively cleaned and converted to other products.
Cylinder Ø35 in to 95 in (920 mm to 2,500 mm)
Height with direct drive110 in. to 335 in. (2,900 mm to 8,550 mm.)

Silos

Stock Silos - eFACTOR3

Stock Silo

Stock Silos are used for interim storage of sophisticated and high-quality bulk solids, such as pellets, raw material or powder. We offer standard silo diameters up to 110 in (2,850 mm) but we will gladly add additional diameters for our customers.

ProductsFor example: plastics, raw materials, pellets, agglomerates, flakes, cut / ground freight.
FeedingTangential feeding via pressure transport.
ManholeManhole with end switches for better maintenance of the silo.
VolumePer demand.
MaterialsAluminum, standard- or stainless steel.
Railing/vertical ladderOptional, with guard rails on top and vertical ladder, including back protection.
OptionsOther options and sizes available on request.

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.

Kreyenborg Fiber Silo - eFACTOR3
Low bulk densitySpecially for the processing of fibers with a low bulk density. Also suitable for various flakes and powder.
Bulk densityBulk densities of 3 – 6 lbs/ft³ (50 to 100 kg/m³)
Agitator shaftThe agitator feeds the material continuously towards the discharge screw.
Material SizeTypical fiber lengths are 0.4 – 1.2 inches (10 to 30 mm) in length
FeedingTangential feeding via pressure transport.
ConicalThe conical design ensures a sloughing of the material and prevents bridging of the material.
OutletUp to 3 controllable material outlets possible.
DischargeConsistent and adjustable discharge by means of separate discharge/ screw.
ManholeManhole with limit switches for better maintenance of the silo.
VolumeTypical fiber lengths are 0.5 to 1 in (10 to 30 mm) in length.
MaterialsStandard- or stainless steel.
Railing/vertical ladderOptional, with guard rails on top and vertical ladder, including back protection.
OptionsOther 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.

Film Flake Silo - eFACTOR3
Low bulk densitySpecially for the processing of film flakes with low bulk density.
Bulk densityBulk densities of 1.5 – 20 lbs/ft³ (20 to 300 kg/m³)
Mixing ScrewThree vertically-mounted mixing screws.
HomogenizationConstant movement of the material promotes homogenization of film flakes of variable thickness and size.
Material SizeFilm flakes are up to 1 in (30 mm) in length.
FeedingTangential feeding via pressure transport.
No Dead ZonesSpecially shaped silo to avoid dead spots.
DischargeConsistent and adjustable discharge via a separate discharge screw.
ManholeManhole with limit switches for better maintenance of the Silo.
VolumeVolumes from 105 ft³ to 1,400 ft³ (3 m³ to 40 m³).
Materials Standard- or stainless steel.
Railing/Vertical LadderOptional, with guard rails on top and vertical ladder, including back protection.

Block-Type Silo

Storage and dosed discharge of ground- and sensitive materials ( e.g.: film flakes, fibers, foams, etc.)

Block-Type Silo - eFACTOR3
Low bulk densitySpecially for processing of materials with low bulk density.
Sensitive bulkSpecially suitable for sensitive bulk.
Bulk densityBulk densities of 3 -15 lbs/ft³ (50 to 200 kg/m³)
FeedingTangential feeding via pressure transport.
LooseningThe bottom of the substructure contains a twin discharge screw and stepped loosening elements that prevent the material from bridging.
DischargeThe material sinks smoothly. A trough screw extending over the complete length of the silo ensures a uniform and adjustable discharge.
ManholeManhole with limit switches for better maintenance of the silo.
VolumeBy default, block-type silos with a volume up to 2,100 ft³ (60 m³) are available.
MaterialsStandard- or stainless steel.
Railing/vertical ladderOptional, with guard rails on top and vertical ladder, including back protection.
