Kahl Puts Experience To Pellets Production

For decades Kahl pelleting plants have been applied successfully for compacting organic products of different particle sizes, moisture contents and bulk densities. Kahl is constantly developing the machines in order to improve capacities and economic efficiency.

The pelleting presses are particularly appropriate for products which are difficult to pellet. Depending on the input product, which can be dry wood shavings, wet sawdust, wood chips or even whole tree trunks, different process steps are required.

Directly before the pelleting press, what is needed is a product with a granular size of approximately 4 mm and a residual moisture content of approximately 10%. This means tree trunks require the maximum process steps: debarking, wet chipping, drying, dry grinding, pre-conditioning, pelleting, cooling, storing or loading.

If wet sawdust is available, for example, drying with Kahl belt dryer will be the first process step. In case of dry, precrushed product, the actual pelleting plant starting with preconditioning will be sufficient.

Amandus Kahl offers pelleting presses with a drive power from 3 kW to 500 kW. In total, 13 different sizes are available. The production capacities of most plants range between 1.5 and 8 t/h. Smaller plants work efficiently, too. Larger plants of up to 40 t/h are provided for industrial production of pellets.

Kahl services include consultation, assistance in obtaining approval, engineering, commissioning, installation and after-sales service.

Kahl supplies turnkey plants for the recycling sector. Product tests can be carried out in the Kahl pilot plant.

Possible applications of the Kahl pelleting press include wood shavings, wood chips, sawdust, wood and sanding dust, straw, miscanthus, bagasse and other biomass.

Buettner Provides Range Of Dryers

Buettner offers the full range of dryer technologies to the biomass industry, ranging from ultra-low temperature belt dryers to direct heated rotary drum dryers and indirect heated dryers.

For low quality heat, such as 70° - 100° C (160° - 210° F) hot water, low temperature exhaust boiler gases or low pressure steam in the range of 10 to 30 PSI, ultra-low temperature belt dryers are recommended. Such dryers compensate the low calorific value of the heat with relatively large air flows to generate the required energy for drying.

For higher quality heat sources, such as medium pressure saturated steam 70 – 230 PSI or thermal oil 150° - 300° C (300° - 570° F), Buettner offers its indirect heated dryers to the biomass market. This type of dryer is often utilized in cogeneration plants as a condenser for saturated steam coming off a turbine. The drying of wood biomass material is performed in a stationary housing that contains a rotating heat exchanger. The transfer of heat into the wood material is done by contact heat, and the transport of the wood chips through the dryer is mainly mechanical, thus the exhaust air volumes are very limited, reducing the need for air cleaning equipment significantly.

Buettner also offers a wide range of thermal heat generators, ranging from low NOx suspension burners to large grate fired furnaces. Visit

New Horizontal Grinder Revealed

After more than a year of rigorous design review and extensive in-field testing, Morbark has released its new 3800XL horizontal grinder to the market. Not simply an incremental extension of the 3800 platform, this new grinder contains significant changes and improvements in feeding technology which dramatically increases production capacity and operating efficiency, according to Morbark.

The primary difference in this unit is its redesigned reverse-pivot feed system which minimizes space between the feed wheel and the hammermill. There is no place for material to hide in this unit, which keeps debris moving forward with uninterrupted, steady production.

The Morbark 3800XL is available with a variety of engine choices up to 800 HP. Visit

Ukraine Pellet Mill Orders Drum Dryer

Schenkmann-Piel-Engineering has received an order for a drum dryer with an 11 MW light oil/wood dust burner for drying sawdust for the production of wood pellets from Skala Energy Ltd. in Tiachiv in Ukraine.

The required process heat will be produced in an integrated vertical steel burning chamber with perforated plates for cooling. According to the company, this concept brings the following advantages: automatic cleaning of burner ashes; no need to install expensive refractory lining; no mixing chamber needed; lower maintenance on the burning chamber; lower investment cost.

At the end of the drum cycle the material is separated from the airflow in the cyclone battery. For optimal energy utilization the gases are then partly redirected to the mixing/cooling vertical steel burning chamber.

The completion of the assembly and the production of the first dried particles will take place in May.

Mobile Chipping Package Introduced

Fecon offers the RTC22/500 as a turnkey mobile chipping package. Mounted on a TimberPro 830B forwarder it is the fastest American made all-terrain chipper, according to the company. It is highly productive in land clearing, biomass, pipeline and R.O.W. applications. The 8-wheeled off-road chipper gets to work at up to 12 MPH.

The Fecon RTC22/500 more than triples speeds of typical track chippers. Production speed is further enhanced by both loader reach and lifting capacity. It sets new standards with 12,880 lb capability at 15 ft. and up to 31.5 ft. of total reach and 360° rotation. The in-feed power of over 16,000 ft. lb. of torque provided by Fecon’s Power Feed Management and optional dangle head felling saw make the RTC22/500-8 a highly effective stand-alone chipping system.


Bruks Reports More Sales, Expansion

BRUKS reports its sales of mobile chippers has doubled in the past two years, which is why the company has increased its production capacity and is about to open a new assembly plant in Norrborn outside Bollnäs, Sweden. The plant comprises some 4000 sq. m. and will initially employ 20. The new plant will also be used for the assembly of BRUKS’ stationary machinery that, too, is showing increased demand.

Group sales increased by about 110% during the first two months of this year compared to the same period last year, BRUKS is planning to increase office staff by some 20 new employees in Arbrå and Örnsköldsvik during the coming months. It has already increased production staff in Arbrå.

“We’re observing significant growth within bioenergy and pulp and paper,” says CEO Anders Gustafson. “It really feels good to have left the financial crisis behind us and start planning for expansion and growth again.”

New Walking Floor Increases Payloads

The Titan Trailers streamlined Walking Floor model is designed to reduce weight and increase payloads by up to 2,000 lbs. The new thinwall aggregates trailer features a narrower body with lower sidewalls that, along with Titan’s patented aluminum body construction, achieves significant reductions in tare weight compared to similarly sized belt-out trailers, according to the company. Inside is the latest 6-slat V-Floor self-unloader from Keith Mfg. Co. Titan has enhanced the system with an integral V-Plow self-cleaning system.

The trailer’s 102 in. frame mounts a narrow 68 in. wide body, which reduces the overall weight while providing aggregate haulers with ample room to load maximum weights. The narrow smooth-sided body also streamlines the trailer for further fuel savings, a lower center of gravity and improved tracking on the road. Visit

New Rotary System For Thick Bin Walls

BinMaster Level Controls has introduced a horizontal rotary extension that provides the ability to install a rotary through the side of a bin wall, such as those in concrete silos, up to 12 in. thick. This rotary extension design allows for rotaries to be side-mounted with minimal risk of damage during operations. This optional assembly includes an extended drive shaft with a protective shaft guard that keeps the shaft centered and BinMaster’s “no packing” seal at the end of the shaft. Standard lengths of 6 in., 8 in., 10 in. or 12 in. are available for both the MAXIMA+ or BMRX rotaries.

When fitted with BinMaster’s collapsible paddles, the rotary can be easily installed through an existing 1-1/4 in. or 1-1/2 in. opening, so there is no need to enter the bin to install or remove the rotary. Plus, the horizontally extended rotary design features a unique protective bearing at the end of the shaft extension that forms a seal between the rotary shaft and the shaft guard. This bearing prevents bin material from getting packed up into the extension and causing the rotary to give a false “full” signal when the paddle stops turning. Visit
