Wood Flour
Wood Fiber Powder · Fine Wood Fiber · Pulverized Wood
Wood flour is a finely ground wood product manufactured from sawdust, wood chips, or other wood-processing byproducts. The material is lightweight, highly absorbent, and commonly used as a filler or reinforcement in composite products. Due to its fine particle size and low bulk density, wood flour can be difficult to handle and is prone to dust generation, bridging, and compaction. KWS designs specialized conveying systems that provide reliable material flow while minimizing dust emissions and maintaining product quality.
