Sawdust grinder known as (end mill shavings, sawdust machine) is the production of high quality flour (sawdust) of a special equipment, widely used in papermaking, mushroom, charcoal, chipboard, sawdust board, HDF, MDF preparation steps and a single board, and other industrial production, wood flour (sawdust) production base, the main raw material mill cutting logs, branches. This series of sawdust grinder (wood cutting machine) using low-pressure or high-voltage motors, large sawdust grinder (wood cutting machine), there pulley drive and direct-coupled drive in two; the level of feed points and tilt two ways, the material also has on the loading and discharging of two ways. Internal structure is mainly composed of sawdust grinder on the body, lined plate, grinding tools, consisting of the lower body, rotor, fan, discharge tubes, chassis, bag filters and other parts. The device's unique lined plate to increase the extent of wear and equipment; dust removal equipment more humane solution to the problem of dust pollution. Workers will not be dust pollution when in operation, while the finished product is very clean break. Efficient sawdust grinder works efficiently sawdust grinder machine cutting blades and high-speed airflow impact of the collision crushed dual functions in one, and can be completed at the same micro-material sorting and processing operations. In the process of crushing the cutting blade, rotor speed airflow generated, with the direction of rotation of the cutting blade, the material in the gas stream to accelerate and repeated impact of materials while being double smash, smash rate accelerated material. Use of blade cutting and high-speed airflow impact of the collision crushed dual functions in one, and can be completed at the same micro-material sorting and processing operations. In the process of crushing the cutting blade, rotor speed airflow generated, with the direction of rotation of the cutting blade, the material in the gas stream to accelerate and repeated impact of materials while being double smash, smash rate accelerated material. Equipment use paper with a wood chipper is the paper's necessities, and the wood chipper is specifically with a variety of wood, branches, wood waste, wood and other materials processing out of the paper can be used as a raw material, market paper mills are using this technology to the processing of the product produced models.
