KeFan Wood Powder Machine is a kind of advanced superfine wood powder equipment, which is recently developed by technicians of the company. Through innovation of integrating the crushing principle and of all kinds of traditional wood powder machine both at home and abroad. It has successfully developed to a new type high-efficiency energy-saving wood powder crusher. The powder making machine has fineness analyzer and is a new type powder manufacturing equipments specializing in special difficult crushing such as light material, material of fiber type, brittle and flexible material etc. the feed opening of this machine adopts automatic absorbing type feed and can ensure safety in production, which overcomes the disadvantages of serious damages of machine caused by direct feed and careless throwing of metal block. With fine manufacturing, high processing technology, the machine adopts double layers of machine body. The injection of running water into machine body performs the function of water cooling. A new type material is installed in the machine body, which fulfills the function of sound insulation and heat abstraction. So this machine has little noise and no vibration in production.
