Sawdust machine works and their uses: sawdust machine, also known as wood grinder, it is the use of a blade cutter cutting and high-speed airflow inside the impact of the collision crushed in one dual function, and can be completed at the same time the micro-feed points selection step of processing. In the cutting blade during the grinding timber, the rotor capable of generating high-speed air stream, with the direction of the cutting blade is rotated, the material to be processed in the rotating gas stream to accelerate, and repeated impact while processing the material so that the material subject to double pulverization acceleration crushing rate material. Multifunction machine with wood chips are widely used in papermaking, mushroom, charcoal, chipboard, sawdust board, HDF, MDF and some industrial production, the first step preparation section and a single wood flour (sawdust) production base, cutting various types of raw materials division, mainly logs, branches. Sawdust machine (wood grinder) set slice, crushing as a whole, the diameter of 1-25 cm chips twigs and branches, but also for some chips fibrous materials like bamboo stalk, grass, corn stalks, sorghum and so on. Sawdust machine is the vast number of manufacturers in the wood processing customers and friends in an important and integral part of the superior equipment.
