Wood chip - Import export

The first examples of which were built by CMC TEXPAN in the early 1990s.They are aimed at cleaning the material ow fed into the machine byremoving any possible contaminants, the density of which is higher than that of the processed wood chips, e.g. stones, sand, metals, rubber, coarser chipsetc.The principle of operation is based on densimetric separation chieved in a vibratory box. In addition to the vibration of the machine casing, the materialow is subjected to a strong, pulsating air ow, enhancing the separationeect and providing for further “dry leaning” of chips. Heavy contaminants (e.g. stones, glass, rubber and plastic) are removed from the material ow,discharged from the machine side and conveyed to further re-classication,while clean chips are discharged from the machine’s front end.

Drum chippers are used to process long and short logs, wood pieces, saw mill waste, veneer waste, residual wood, and other wood waste to high-quality chips. Depending on the size and design of the drum chipper, the machine can be adjusted to the type of wood to be processed and the desired chip quality. The most suitable chipper size is determined by the maximum trunk diameter to be processed and the desired production capacity. The desired chip length also inuences the performance of the chipper. Key features Adv Large draw-in rollers for process-reliable wood feed at constant speed Pivoting feed system for automatic adjustment to loading height Hydraulic ywheel drive for consistent contact pressure and the damping of impacts Robust, well-balanced rotor Large ywheel inertia to compensate for short-term peak loads Generously dimensioned V-belt drive Startup process via Pony-motor to reduce spikes in power supply during acceleration of the rotor

Disc chippers are especially suitable for processing straightly grown round wood into high quality wood chips. The raw material is fed into the chipper via a slanted horizontal feeding conveyor. The disc inside the housing is equipped with knives. The logs are processed to chips between the vertical rotor knives and the counter knives. The chips are discharged below via a discharge chute, with lling level control, to a subsequent conveyor. Advantages High, consistent chip quality Quick, ergonomic knife changes Cutting force supports material infeed Features, Function Chip length 20-25 mm Chip width 4-10 mm Options Adjusting devices for rotor and stator Knives

The long-wood line is designed for processing logs with lengths between 3 and 8 meters and diameters between 50 and 850 mm: With the log feed, step feeder, debarker, washing system, dosing system all the way to the highly-ecient disc chippers, the production of high-quality chips is guaranteed. Key features Feeding of wood by means of handling cranes or loading vehicles Robust chain cross conveyors for the direct feed of logs Buer capacity of up to 30 minutes/ 80 metric tons bone dry material Step feeder for absolutely consistent volumes Metal sensor and roller conveyor cleaning system Rotor debarker for eective debarking even at extremely low winter temperatures Robust drum chipper Advantages Highly controllable wood feed Ecient debarking Perfect chip quality thanks to the adjustability of to the feed material mixture Minimal ne material content High lling level and high utilization of chipper c High operational safety
