The Design of YQP36 Disc Prewatering Pelletizer
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.

1 前言
预加水小料球快速煅烧技术，小料球快速烧成技术是立窑煅烧的一项重要技术进步，目前应用十分成功的企业并不多，主要原因是前几年预加水成球系统的控制技术和设备还不太过关，小料球的操作控制要点还没完全掌握，目前预加水成球技术已经发展到第六代产品，设备及控制系统基本过关。这些都是能否取得高产量、高质量料球的保证，从而提高水泥的煅烧质量和产量。
