Chip drying - 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.

The Centrifuge takes in a slurry of chips and coolant, separates the coolant out by high speed spinning, leaving dry chips.

The lift bottom centrifuge is designed for continuous operations. This up and down motion of the live bottom pushes the chips upward through the sieve. The centrifugal force, up to 500 times the force of gravity, will dry the chips, resulting in the maximum degree of de-oiling. The remaining oil content is extremely low. The dry chips fall down over the edge of the drum into a container. The are different models and different drives available.
