Experiments show that the wear rate of the hous ing’s rear wall is reduced, along with the loss of chips and the noise level Introduction. For the chemical pulp process, where wood fibres are disintegrated through the action of chemicals, one important parameter is the chip thickness, since it governs the penetration of chemicals The opportunities for improving chip quality are, inter alia, in the system of chipping wood and transport of wood chips. Chip of arbitrary width is obtained; its repeated processing represents an unwanted expendi ture of time and money. The proposed wood chipper (Figa) is intended to produce Low-Power Cylindrical Wood Chipper Power Unit by Using Alternative Fuel Łukasz Warguła *, Mateusz Kukla, Piotr Krawiec and Bartosz Wieczorek Faculty of Mechanical Engineering, Institute of Machine Design, Poznan University of Technology, Poznan,´ Poland; @ (M.K.); c@ (P.K.); The range of chip sizes obtainable in chippers include; mm (1 toinches) in length, mm (1/2 toinches) in width, and () mm (¼inch) thick [15] Existing wood chippers employ cutting plates with a plane front face and a rectilinear cutting edge. (Spinelli et al.,) Abstract. The force relations and dynamics of cutting knife in a vertical disc wood chipper were investigated. This paper will show how the chip quality problems at the industrial plant can be solved. Chippers are comminution machines used to produce wood chips and can be divided into two types; the disc and drum chipper, where the disc chipper has simple design and higher energy efficiency than the drum chipper, despite the drum chipper has more productivity but it’s insignificant. Chip size is controlled by knife angle, log orientation and wood grain direction. (20o); Shear angle, (φ = o); the mean frictional angle, (τ = o) In our improved woodchipper design, impact of the chip at the wall is prevented by equipping the cutter disk with plates that direct the chips to the capture zone of the blades. The deficiency of this design is nonuniformity of the chip produced. KEYWORDS: Wood chipping, chip PDF Mobile wood chippers represent a mature technology now available in a wide range of sizes and configurations.
