Wood chippers produce wood powder is a new front-ideal for the production of woodworking machinery and equipment. He can be wood, with branches once processed into wood chips and other raw materials, low investment, low energy consumption, high productivity, good economic returns, ease of use and maintenance. The sawdust and wood grinder? Especially suitable for edible fungus medium wood processing, mainly by means shavings, crushing device and fan components. Wood shavings size timber by means of cutting back is small, it can feed without pulverizing apparatus further dried pulverized wood machine finished crushed aggregate supplied by the fan site. Equipment package with only one motor driven, simple structure, compact layout, the price is cheap, stable, low energy consumption, high yield, good quality of finished wood machine, low processing costs. In addition to wood chips can also be used bamboo, grass, corn stalks, sorghum stalks wood chippers wood chippers and other fibrous stalk-like material. Sawdust machine, wood sawdust machine, wood sawdust machine, chips machine, wood grinder can be processed, pine, poplar, Yang wood, fir, bamboo, because the structure is compact, small footprint, good chip quality, low power consumption, and is suitable for mobile operation, widely used in small and medium sized enterprises particleboard and fiberboard production preparation steps can also be used for self-employed production of wood production. 1, by the body, in the body, lower body composed of three parts. 2, grinding tools, 7-type knife, a knife-type knife and centrifuge components. 3, pay machine is composed of; fan, powder collector, dust composition. 4, the host grinding chamber 7 type knife, a knife and centrifugal type knife, coarse grinding, fine grinding and centrifugation to re-grinding, grinder rotor driven by the motor at high speed, the mechanical grinding to produce high-speed airflow to produce high-strength materials the impact force, compressive force, cutting force, friction, to achieve a unique shredding. 5, the three blade cutting grinding process, the rotor produces high velocity airflow direction of rotation with the blade, the material accelerates and repeated shocks in the gas stream, cutting friction, but by three pulverization, crushed material into the air analyzer analysis, due to a centripetal force of airflow in the rotor by centrifugal force Shiyou parser, so when the centrifugal force is greater than the centripetal force, the fine particles into the air to collect dust collector, centrifugal coarse particles into the grinding chamber continues to re-crushed until you are satisfied fineness.
