A Review Paper on Optimization of sugar Mill Headstock

Sugar is produced in sugar factory. Juice is extracted from the sugar cane with help of sugar mills. A lot of Pressure generates during the juice extraction process and to sustain this pressure mill should be strong, and should be verified. Headstock is a highly stressed part of mill. It carries rollers and trash plate assembly. They have to sustain forces experienced by rollers while exerting juice from the cane. It is observed that forces due to power transmission and dead weight have not been considered earlier, in order to calculate exerted forces on headstock during mill running closer to actual force Hydraulic force, force due to power transmission, & dead weight are considered. These forces are distributed on sugar mill headstock. So, in order to sustain the Headstocks against all these forces the static analysis is carried out by using ANSYS workbench software, and Weight optimized by changing the inner parameters of the headstock part for permissible stress value with the help of results of previous model. Comparison of both old and modified model of headstock has been done at the end to understand the changes occurred in Modified Headstock.

蔗糖在糖厂中制备。甘蔗汁通过甘蔗压榨机（sugar mills）提取而来。在甘蔗汁提取工序中会产生较大压力，为承受该压力，压榨机需具备足够的结构强度，并需通过可靠性验证。主轴箱（headstock）是压榨机上受力最为集中的部件，用于承载压榨辊与排渣板组件（trash plate assembly），需承受甘蔗压榨提汁过程中压榨辊所传递的各项作用力。此前的相关研究未纳入传动载荷与自重载荷，为更精准地计算压榨机运行时主轴箱所受的实际载荷，本次研究将液压载荷、传动载荷与自重载荷均纳入考量。上述三类载荷均会作用于甘蔗压榨机的主轴箱。因此，为使主轴箱能够承受上述所有载荷，研究团队采用ANSYS Workbench软件对其开展静力学分析，并结合前代模型的分析结果，通过修改主轴箱的内部结构参数，在满足许用应力要求的前提下实现了重量优化。最后，研究对原主轴箱模型与优化后的主轴箱模型开展对比分析，以明确优化后主轴箱的性能变化。
