Shredded bark is burned as fuel to generate energy. It is indispensable to supply uniform particle sizes to energy plants. The degree of preparation is determined by the shape and arrangement of the beaters and size reduction elements as well as the rotor speed. Features, Function Shredded bark is fed to shredder from above Rotor with vertical shaft and equipped with oscillating beaters Inside wall of lower housing equipped with size reduction elements and wear plates Gravity discharge of shredded material to below Easy access to lower part of housing for maintenance Advantages Suitable for almost all types of bark High operational safety No risk of clogging, even with longer or wet bark pieces Insensitive to foreign matter of any kind Optimally adaptable to any feed material Maintenance friendly High throughput capacity Low energy requirement

Double stream mills are used to grind core layer flakes or course material rejects from screening processes to fine surface layer flakes. In the wood-based materials industry they are the ideal solution when it comes to the further refinement of flakes. The produced fine flakes are used in surface layers for particleboard, for example, in the furniture industry. Surface layer mills are part of a reliable machine technology. In the refinement process of flakes, which were primarily produced with knife-ring flakers type PZKR, these mills produce high-quality surface layer flakes. Features, Function Material feed via vibrating chute Heavy-particle and magnetic separator Pneumatically supported transport of the ground material inside the machine Size reduction between beater plates and grinding segments Selectable grinding track geometry Interchangeable screens with different mesh sizes Advantages Compact design Separation of heavy particles and ferrous metals Low...

For the economical re-chipping of sawmill waste, veneer/plywood waste, screen oversizes and particleboard waste. The machine can be mounted e.g. under the chip screen without intermediate bin. Advantages Adaptability to various material Simple but heavy duty design Extraordinary sturdiness Low maintenance requirements High throughput capacity Low operation costs Quick screen and knife change

At the beginning of the process for manufacturing wood-based panels is the technology for the professional size reduction of the different wood types. The quality of the chips, strands, flakes, or fibers determines the quality of the panel. Anything neglected at this stage of the process cannot be made up later on. For this reason Siempelkamp offers the complete range of machines for the production of high-quality chips. Technological competence and intensive development work, based on market and customer requirements, result in optimal customer-specific solutions. The OSB line is designed for processing logs with lengths between 3 and 4 meters and diameters between 50 and 850 mm. With the log feeder, debarker, dosing system, bundle maker all the way to the world‘s largest knife-ring flaker, the production of high-quality strands is guaranteed. Features, Function Feeding wood by means of handling cranes or loading vehicles Robust chain cross conveyors for the direct feed of...

We have developed the world’s largest strander: Due to the design of its knife ring with a 2,500 mm diameter, a cutting width of 850 mm, 56 knives, as well as a maximum material throughput of 45 metric tons per hour bone dry, the new OSB flaker is considered a giant. Stranders of the PZU series are able to process logs to high-quality strands with a specific length, width, and thickness. Therefore, these machines are the best choice for the production of high-quality flakes in large quantities for OSB and wafer boards. Advantages Very good ratio between loading and cutting times Improved, simpler maintenance High strand throughput High strand quality with low fines content Low energy consumption

Drum chippers prepare long and short round wood, slabs, saw mill waste, veneer waste, board trimmings, and various waste wood into high quality wood chips. Annual plants such as cotton stalks or bamboo can also be processed. The drum chipper size and design can be tailored according to the wood type or infeed material to be prepared and the desired wood chip quality. The most suitable sized chipper is determined by the maximum infeed diameter to be processed and the desired throughput capacity. The required chip length will also influence the performance rate of the chipper. Characteristics, Function Large feed rollers assure a process reliable infeed at a constant speed Pivoted feed system for automatic adjustment of the infeed height Hydraulic swing drive system for constant pressure and shock absorption Robust, electrodynamically balanced chipper rotor Large flywheel effect to compensate for sudden peak loads Amply dimensioned V-belt drive Start process supported by...

The Impact Hammer Mill, series PHPH ''Grizzly®'' was developed for the economical size reduction of residual- and waste wood of any kind. Not only pre-broken waste wood but also non precut, long recycling wood can be introduced into the mill. The machine distinguishes itself by high throughput rates at low specific energy consumption, low operating costs as well as robust and durable design. Any wood prepared with the „Grizzly®“ is used as a high quality and uniform raw material for material and thermal recovery. Characteristics, Function Material is fed horizontally from the front Size reduction is performed by impact and breaking combs and breaking ledges arranged behind the rotor Collection device for larger foreign objects which can be hydraulically opened for emptying Robust, wear-resistant and multi-split housing which can be easily opened via a hydraulic system Machine parts in the size reduction area made from wear-resistant and durable materials Oscillating hammers...

Correctly processed residual wood and waste wood constitute a valuable raw material. The Impact Hammer Mill, series PHPS converts pre-shredded residual wood and waste wood of any kind into valuable raw material for material and thermal recovery. Even contaminated materials can be processed. Heavy foreign objects in the feed material are separated and automatically discharged. Characteristics, Function Material feeding is vertically from above Heavy, rotating hammers break the material and throw it against the impact plates The wood is split along the grain and enclosed metal contaminants are set free, separated and discharged Further processing of the wood pieces is effected by stationary breaker and comb bars The end fineness is determined by the perforation of the integrated screen Split housing design allows hydraulic opening Sturdy disc rotor is stress-relieved Adjustable separation degree of the discharge chute for metal pieces Device for hydraulic hammer...
