Tamar Organics Takes Delivery of Two More Doppstadt Machines


Tamar Organics has purchased a Doppstadt DW 3060K Bio Power shredder and a Doppstadt SM 620K Trommel from main distributor Blue Machinery (London) Ltd. These new highly productive mobile machines join two other Doppstadts already in the Tamar fleet, both of which have given sterling service over the years.

Tamar Organics – a wholly-owned subsidiary of Tamar Energy, a leading specialist in the production of renewable energy from anaerobic digestion plants – manages and operates in-vessel (IVC) and open windrow (OWC) composting services to the most stringent quality standards, producing high quality, nutrient rich and peat-free bio-fertiliser. Tamar Organics’ Divisional Manager Andy Sibley said “The DW 3060K will work between two sites processing in the region of 50,000 tonnes of green waste a year while the SM 620K will be based at our Tempsford facility, screening around 35,000 tpa of green waste”. He continues “These machines have impressed us with their low running costs and reliability and Blue Machinery’s parts and service back-up is excellent, knowledgeable and timely”. Matt Scott, Blue Machinery’s Area Sales Manager said “Tamar undertook a detailed analysis of what is currently available on the market and the Doppstadt machines proved to be the best solution for their requirements”.

The crawler-mounted Doppstadt DW 3060K Bio Power heavy-duty shredder is capable of handling large bulk timber and wastewood, mixed construction waste and industrial refuse. This single shaft shredder has numerous beneficial features, which include: Optimum tooth arrangement on the 3m wide roller which rotates at 31RPM; 21 roller teeth and 22 comb teeth which ensure comprehensive shredding of the feed material; reversible fan wheel; generous hopper shape and size for easy loading; electrically controlled roller reversing and a large return conveyor. Additionally, the shredder is equipped with a hydraulically foldable rear conveyor which contributes to a fast set-up time once on site. The DW 3060K is equipped with a 320kW (435HP) Mercedes-Benz diesel engine which has power to spare for heavy duty applications and processing multiple waste material types, producing recyclables to exacting specifications and enabling significant volume reductions – all with a reliability, productivity and fuel economy which belie its size. An additional benefit of this machine is the tracked chassis which allows one operator to load and move the unit, saving time and reducing operating costs.

The Doppstadt SM 620K features the well-proven trommel screening drum construction with interior helix, which enables space-saving horizontal machine installation. Designed and built for the screening and separation of domestic, green, C&D waste and wastewood this machine is also ideal for the production of biomass and RDF. The trommel drum has a large screening area of 38.8m² and a rotating speed of up to 15RPM. Replaceable screens, a variety of ancillary equipment and choice of mesh sizes allows this flexible machine to be adjusted and reconfigured for a wide variety of screening tasks and feed material. An efficient mechanical power transmission features direct chain wheel drive, with geared motors at the drum surface, and the variable speed provides optimum adjustment for regulation of the screening quality. State-of-the-art SPS control makes for easy and precise operation and access to the machine’s performance and operating data. The self-propelled crawler undercarriage provides agile mobility for working at chosen locations throughout the site as required.
