The pre-crusher, type PBEW "Dracula" was developed to improve the capacity of downstream preparation machines and the size reduction of voluminous residual and waste wood such as packaging materials, pallets, construction wood and old wood furniture. The pre-crusher, in special design, is also suitable for the size reduction of flake- and MDF-packages. The voluminous feed material is pre-cut and dosed into the downstream process. Characteristics, Function Material feeding by means of a wheel loader or conveyor belt, depending on the installation of the machine Generously sized infeed chute which at the same time serves as a storage bin A slow-speed rotor tears off parts of the feed material which is further crushed on the downstream breaking combs Rotor drive via gear motor, elastic coupling and multiple chain Lateral material discharge Built-in grates determine the size of the end product Advantages Slow-speed rotor, therefore extremely quiet operation Easy feeding due...

The quality and consistency of flakes have a significant influence on board properties. Knife-ring flakers are flexible and can be individually adjusted to meet flaking requirements. The professional preparation of chips leads to the right flakes for particleboard. Features, Function Chip feed system with vibration chute and magnetic drum Integrated heavy particle separator "Cleanomat" Impeller used to distribute chips Counter-rotating principle of the knife ring Chip width adjustable by knife protrusion Bottom discharge Advantages Consistent flake quality High throughput rates Quick knife changes Precise knife adjustment Uniform utilization of all knives No clogging even at high moisture content Economic to operate and maintain Robust, reliable, and durable

The Hammer Mill, series PHMS is used for the economical preparation of wood chips from round wood, residual wood, waste wood or annual plants. The wood chips are of high quality and can be directly injected for combustion, or used as flakes for briquetting and pelletizing. Due to their quality they are also used for the production of core layer and surface layer material during the production of wood-based panels. Characteristics, Function Material is fed vertically from above The gravity sifter "Cleanomat" separates heavy contaminants from the feed material Flat steel hammers rotating at high speed split the feed material into flakes Stationary impact elements support the size reduction process and relieve the screens The perforation of the screens determines the size of the flakes The symmetrically designed machine housing allows operation of the mill in both directions Rotating flat steel hammers can swing back when large foreign objects penetrate into the grinding...

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...

Surging demand by the pelletizing industry has caused a shortage of available saw dust and shavings. Numerous industries, like wood–based panelboard producers and the power plants are forced to find alternative sources. Substitution of suitable replacements has become urgent to ensure a fibre supply and to prevent shortages. Wood chips are often the only available source. Because of increasing numbers of produc-tion lines for pellets and particleboard a shortage of small fibre, has resulted. The flake produced from wet wood chips by the optimally PHMC hammer mill, can be used as an additional source or a 100% substitute of saw dust. Advantages Processing of wet chips (moisture u > 100%) Flake preparation of chips to a coarse saw dust type material Ensure the fibre supply in existing processing lines High machine availability at lowest maintenance an labour costs Independence from saw dust supply Future-proof for the usage of different material types by simple adjustment of...

The Pallmann Depither, series PMS "Centurion" is used for depithing of sugar cane bagasse. The retained bagasse fibers are used for the production of cellulose, the production of fiber boards or for the production of particleboards. Furthermore, the depither can also be used for the preparation of other vegetable raw materials. The machine is designed for the wet preparation, moist preparation or dry preparation processes. Characteristics, Function The material is fed from the top The rotor is vertically arranged with bearings on both sides and equipped with hammers that can be used on both sides The hammers are free swinging and armoured at both sides of the tip Material preparation and separation of the pith from the fiber is performed by means of impact and friction Longer fibers are retained by a screen while the pith and the fines are discharged through a screen with the air flow Pith and fibers are discharged and transported separately Advantages High throughput rate...

The Double Stream Mill, series PSKM is used for the fine preparation of precut wood chips and annual plants such as bagasse, miscantus, cotton stalks, hemp stalks, corn straw and rice straw. The fine flakes produced are characterized by their low percentage of dust and coarse particles. The areas in which the end material is used are diverse. It is used for energy generation, as insulation material, the reinforcement of building components and as raw material for the production of fine surface layers of particle boards. Characteristics, Function Compact and sturdy, designed for continuous operation Bearing- and drive system easily exchangeable as a complete unit A slide to remove the grinding ring is supplied as standard. Dismantling of the impeller is not necessary Material feeding via vibratory feeder and a feed chute designed as a gravity separator Even distribution of the material in the grinding chamber Size reduction is performed by repeated impact onto the impeller...
