Europe Pellet Project Orders Machinery

Dieffenbacher has received an order from ffk environment GmbH to design a new pellet plant and supply the main pelletizing (Dieffenbacher PelletPress) and size reduction (ClassiSizer) components for the different raw materials. The state-of-the-art pellet plant will be at Forst (Lausitz), Germany and will manufacture composite pellets from waste materials. Production is scheduled to begin in October 2012.

ffk processes biomass and other organic materials such as nut shells, wood, straw, green and household waste with a varying proportion of brown coal, black coal, and pet coke.

The two ClassiSizers will break down the raw materials and produce pelletizable material in different particle sizes. The Dieffenbacher PelletPress produces composite pellets with a diameter of 25 mm and has a capacity of 10 tons per hour in this application.

Debarking Drums Upgraded

Price LogPro has developed a number of new products due to the ever increasing desire to better utilize small wood diameters for biofuel/energy, lumber production, pulping and engineered wood products. Price has been offering mobile and stationary drum systems since the early 1990s to meet client needs to efficiently recover and process raw fiber with the lowest operating debarking cost per ton.

 Price’s debarking drums are of extra heavy duty construction and do not require consumables for debarking, with a proven 15-20-year life span on the drum shell. The Price debarking drum also operates off of a high efficiency electric drive system without the need for hydraulics allowing clients the lowest possible energy costs while protecting the environment.

In recent years the biofuels industry has developed uses for what was normally called “waste wood,” which traditionally was deemed not desirable enough to be processed or recovered. In response to these new “waste wood” applications Price LogPro has upgraded its standard Price mobile/transportable drum lines with new configurations and shell arrangements to handle the needs of the biofuels industry.

Since the introduction of the Price UrbanWood Drum Systems in 2001, user applications have ranged from dedicated storm debris processing, tree service processing, waste wood fiber processing for pellet plants, mulch operations and whole tree stump processing facilities. Urban Drum Systems have been used to upgrade clients’ raw fiber by removing the bark or as a heavy duty trommel screen to separate dirt and rocks from usable fiber, allowing them to sell processed fiber as an upgraded product to be used in pellet production or co-gen fuel while staying within acceptable ash levels. The Price debarking systems have the ability to process fiber lengths from 1 ft. to 25 ft. long and fiber diameters from 2 in. to 40 in. This gives clients the flexibility required to handle different infeed stock.


Advantages Of Drum Chippers Pinpointed

Biomass Engineering & Equipment provides a wide array of products to the quickly growing biofuel industry. With innovative designs such as drum chippers, the company offers the perfect solution for anyone’s needs. Here are just a few reasons you should choose these drum chippers over traditional disc chippers:

  • A more consistent chip size.
  • Provides a more resalable endproduct for fuel or next stage processing.
  • Takes less horsepower to operate, providing energy savings.
  • Less long grain silvers = less screening.
  • Less fines and overs due to controlled feed and precision rollers and knives.
  • Low profile with easy maintenance.
  • Faster knife changes.
  • Thicker knives for greater durability.
  • Heat treated frame for greater durability.
  • Relieves weld stress and has a more stable frame.
  • Precision bearing for less maintenance and less friction.
  • Heat treated and annealed drum shaft for greater strength and durability
  • Shaft is checked via altrasound to ensure highest quality and strength.
  • Shaft attached to drum using expanding rings instead of a key. This makes the shaft stronger and spreads the load out over the whole surface of the shaft.
  • Roll clearance is tighter to make sure all material is fed into the drum.
  • Internal drum cover offers two stage protection and better chip movement within the processing area.
  • Double spherical mounted bearings on the drum shaft for longer life and energy efficiency.
  • Two-anvil system to improve performance and reduce second pass chips.
  • All material being fed into the drum is held by rollers both top and bottom to prevent kick back of material.
  • Internal screens reduce over-size chips from having to go through an external screen.
  • New product 2-year warranty.
  • Everything will be engineered to fit with 3D modeling.


Peterson Names New Distributor In Florida

Peterson Pacific Corp. appointed Peninsula Equipment as the new Peterson distributor for the Florida peninsula and the central panhandle region.

Peterson’s full range of horizontal grinders, disc and drum chippers, blower trucks and screens will be represented by Peninsula. “We are excited to see what they can do with Florida,” says Brian Gray, Eastern Sales Manager for Peterson.

Raw Materials handling Emphasized

GW Systems began focusing on the emerging wood-to-energy market in 2006. Since that time, the company has adjusted its marketing efforts to service the industry and has built a product line of quality, competitively priced equipment. The company’s “Chip to Ship” philosophy has led it to modernize its line of Radial Log Cranes with updated, state-of-the-art structural, mechanical and electrical systems. GW’s cranes, along with a wide range of drum debarking lines, meet most typical production and quality requirements for feedstock for the solid and liquid fuel products industries. Custom design screening, re-sizing and material handling systems round out the company’s ability to be the complete wood year design/build contractor.

GW Systems also incorporates what has traditionally been portable “in woods” type debarking/chipping equipment into fixed location satellite chipping operations such as the one in the photograph. The mill incorporates a GWS 125R25T Radial Log Crane with traveling grapple to feed a combination flail chipper to provide contract chips to the wood pellet plant. The use of the crane allows minimization of the real estate required to store the maximum amount of wood inventory. It also optimizes the feeding of the chipping equipment to achieve the maximum throughput tons per hour of chips. GW Systems offers complete design of these types of facilities, including truck scale systems, screening and rechipping and material handling systems for chip and bark storage, and conveying.

GW Systems has been the contractor for two of the largest wood pellet export facilities in the U.S.
