AUMUND Fördertechnik

AUMUND offers new Conveying Solutions for Alternative Fuels.

In the early 90s AUMUND made news by taking over Maschinenfabrik LOUISE in Cologne. In 2006 AUMUND also acquired WTW Engineering in Cologne. Both companies have engineering, patents, production and sales relatingto rotary discharge machines and drag chain conveyors. The purchase of these companies and their products gave AUMUND the edge in bringing to market discharge systems such as CENTREX® or LOUISE Rotary Discharge Machines and in driving the development of these products. The acquisition of the spare parts business of Maschinenfabrik Besta & Meyer in 2014 rounded off the product portfolio at that time.

Back in July 2019 AUMUND Fördertechnik began increasing capacity in its engineering team; this signalled the startof new product design in conveying and transportation of Alternative Fuels.As AUMUND continues to pursue this strategic path it is now capable of offering an extended range of products for the alternative fuels sector: The offering includes the AUMUND Trailer Docking Station, the AUMUND Moving Floor Conveyor, and the AUMUND RotatingScrew Discharger for the conveying of wood chips, wood pellets, RDF and many more.

AUMUND Trailer Docking Station type TES
The AUMUND Docking Station is particularly suited to truck unloading with autonomous discharge systems suchas walking floors and active or moving bottoms. A separate hydraulic aggregate powers these moving floors so that theunloading of the truck is independent of its traction unit. With the aid of dedusting systems on the Station and a curtain,the discharge effected is largely dust- free. Screw conveyors on the floor of the Docking Station transport the material sideways to an ongoing conveyor.

AUMUND Moving Floor Conveyor type SBA
The AUMUND Moving Floor is a reliable conveyor for easy flowing and sticky materials. The Moving Floor consists ofa special grating which is individually adapted to the characteristics of thematerial to be conveyed. The conveyor slats are each powered by a hydraulic cylinder, AUMUND Moving Floor Conveyor type SBA with individual slats retracting below the material in turn, enabling the complete Moving Floor to bring the material forward in the conveying direction. The Moving Floor can be installed either on a concrete slab or on steel. Classical applications for the Moving Floor are pre- and interim hoppers for wood chips and bark, sawdust, rubber waste, plastic rubbish, sludge, coal-tar mixtures, refuse from the paper industry and many more. Discharge capacities of 40 to 300 m³/h have already been achieved.

AUMUND Rotating Screw Discharger type RAS
The Rotating Screw Discharger type RASis a discharge system for dry or damp bulk materials which do not flow easily. The Screw Discharger travels over the silo floor by rotating around the vertical axis of the cone, and conveys the material into the chute beneath the cone.

The Screw Discharger can be adapted to the individual bulk material by variations in the design of features such as the cladding, the teeth, or the pitch of the screw. Screw Dischargers can be installed in steel or concrete silos. Depending on the material properties and the diameter of the silo, conveying capacities of up to 450 m³/h can be achieved. The maximum silo diameter is currently around 25 metres.

• Slag
• Coal
• Ores
• Fly ash
• Raw Material or
• Alternative Fuels

under severe operating conditions and in continuous operation.

 SAMSON Biomass Handling Solutions
Since the early 1980s SAMSON Materials Handling have developed a range mobile materials handling solutions dedicatedto the reliable intake, storage and export of general bulk cargoes including many unusual and cohesive materials such as Biomass Fuels.

Flexibilty is at the core of the SAMSON`s product concept; from truck intake using the mobile Samson® Material Feeder, through to mobile staching and ship loading solutions able to operate from existing berths.

The goal is to deliver this flexibility without compromising performance, highest environmental standards, safety and reliability.

Biomass transfer to Samson® Material Feeder
Walking Floor Trucks have a live bottom in the trailer floor, comprising reciprocating bars that move back and forth beneath the load and witha moving bulkhead the contents are discharged.

Worldwide there are a vast rangeof truck styles all dedicated to their specific markets and local customs. Standard end tipping solutions are still by far the most popular but in some markets the side dumper is also used.

For the haulage of wood chip in developed markets, the dedicated through dumper trailer gives the maximum payload within established regulations. These trucks are raised on a tipping platform and the wood chip flows through the two bodies exiting via a hinged rear door into the intakesystem at the processor or power utility.

Samson® Material Feeder Road Intake
Wood chip intake from trucks can be a tricky business. Wood chip tends toblock and blind, does not flow easily through inclined chutes and cannot be handled reliably in standard tapered hoppers. In this situation the wide beltSamson® Material Feeder is ideal. Thanks to the wide apron belt design the carrying surface is wide relative to the material depth delivering reliable storage and discharge.

Material is drawn into the Samson®Material Feeder body from the tipping truck in a controlled stream allowing fast truck turnaround, and with minimum free fall, dust generation is mitigated at source requiring much reduced extraction to eliminate fugitive dust nuisance.

Road Intake Stations
For example: at a power plant in Poland, four Samson® Material Feeders receive various types of Agri-Biomass including wood chip to augment the coal stream and reduce the utilities carbon footprint.

These projects are typical of new CHP plant designed to intake biomass to an established power utility.

Import, Transfer and Transshipment The SAMSON STORMAJOR® is a universal equipment suitable for stockpiling, barge loading and rail wagon loading and for the importof wood pellets from small coaster when combined with a grab hopper discharging to existing conveyor systems or storage facilities. The STORMAJOR® is available with a rangeof ancillary equipment such as trimming chutes for loading rail wagon or barge, powered travel for easy movement on the quay or stockyard, on-board power for complete autonomy, requiring noshore power or dedicated infrastructure.

Truck to Ship
By integrating two Samson® Material Feeders to a common outloading boom, the fully autonomous Shiploader may receive almost any bulk cargo including wood chip, pellets or grains directfrom tipping trucks so eliminating the need for intermediate on-port storage. Illustrated here, independent mobile Samson® Material Feeders are used in pairs to load a single Shiploader boom allowing two trucks to be discharged simultaneously.

Dust Controlled Bulk Import
The Eco Hopper receives material by grab from up to Cape Size vessels discharged by mobile harbour crane. With the patented SAMSON dust extraction system and Flex-Flap one way material inlet valve, fugitive dust escape is kept under control.

The Eco Hopper may be either tow travelled or supplied with integral powered travel plus diesel genset for complete autonomy. As with the mobile Shiploader the Eco Hopper may be moved off the berth when not required.

Longitudinal Storage with SCHADE Portal Reclaimers
Most biomass fuels reaching modern dedicated or multi-fuel power plants originate in managed forests or from the residues of timber processes. They are generally broken into wood chip (coin sized pieces of wood) and often then dried and extruded into wood pellets.

Depending on the stacking method definded by the type of stockyard,buffer or blending bed, stacking in open stockyards of longitudinal shape is performed with stackers equipment.

SCHADE offers the longitudinal storage of biomass for example by their Portal Reclaimers.

SCHADE Bridge-Type Reclaimers
The maximum blending effect is no doubt achieved with the SCHADE Bridge-Type Scraper combinded with the relevant stacking method.

As with all SCHADE reclaimers, the scraper chain is designed and manufactured to SCHADE standards. SCHADE scraper chains are also fitted with automatic tension ensuring equal take-up of both strands.
