Abstract: In order to satisfy the technical requirement of prewatering pelletizing in the process of cement production with modern kiln and develop the sixth generation of prewatering pelletizer, the topic which is designed is YQP36 Disc Prewatering Pelletizer. Consequently the proportion of diameters, the high strength, the high holes rate and the high output of raw meal pellets could be assured of. According to the new requirements, the structure, the transmission system and the drawknife system of YQP36 Disc Prewatering Pelletizer are improved and designed. This design has been completed by the method which combines theories design with experience design. The transmission system and drawknife system are optimized basing on that the strengths of chassis and support are assured with analogy design. Firstly, the projects of designation and improvement of prewatering pelletizer are demonstrated, including the structure, the ways of delivering the motivation and drawknife system by referring some improvement experience from production practice; Secondly, based on the analytical results, axial force, the torque and power are computed so that the electromotor, decelerator and other corresponding components could be determined; Thirdly, according to the parameters of the parts which has already been assured, the simple exercise diagram of the transmission device is analyzed and drawn up and the ratios of all levels are assigned. Then the structure design is carried on and the strength of part is followed to be checked. The ways of lubricant and seal of the equipment are determined in succession. Finally, the whole overall arrangement scheme of YQP36 prewatering pelletizing equipment is designed. This design is in the light of the principle of the high yield, high quantity of pelletizing and stable operation. In addition, the requirements of YQP36 will be satisfied, including economy of energy, economy, environmental protection and enlargement.
