Requirements for technological wood chips. Features of the production process.

TD “KMZ” - the expert machine-tool industries develops and sells equipment for the manufacturing of wood chips - disc and drum chippers. The final product manufactured on these machines meets all international quality standards, takes into account the rigid requirements of each customer.
The chips are widely used in various industries. In this case, each direction makes to the product the requirements:
The pulp and paper industry
The chips should have a smooth surface, with a cut angle of 30-60 degrees, the optimal length 15 - 25 mm, thickness 5 mm. the Edge should be no chips, and the scrap should not exceed more than 30%.
Hydrolysis production
Requirements more lenient and mainly relate to the size of the chips. It should not be more than 35 mm long and 5 mm thick.
The production of wood boards
The chips are widely used in the production of fiberboard and particleboard. In the first case its length must be strictly from 10 to 35 mm, and a thickness not exceeding 5 mm. In the second - whereas the method of compaction of slab components. Requirements for wood chips: the optimal length of from 5 to 60 mm, thickness - 30 mm.
Also taken into account the following indicators:
- humidity. For all areas it should not exceed 40%;
- the composition. Every industry prefers a specific type of wood. In some cases, enterprises use a mixed raw material of pine needles and larch;

Features of the production process
The technology of production of wood chips is the use of chipping machines Trading House “Kotelnich mechanical plant”. Also on the line and other auxiliary equipment: conveyors, sorters and much more. Wood waste of large sizes are debarked. Further, if required, is raskraska, cut long items on shorter. The resulting slats, boards are sent to the shredding in a chipper. The finished product is sorted by fractions.
If the wood raw material contains metal particles, you must equip the line magnetic separator that will distinguish and remove extraneous elements.
