Bulk material handling plays a vital role in the effective operation of process industries. In Visakhapatnam steel plant is one such shore based process industry operating at 120% of rated capacity of 3.0 MT/annum. Liquid steel is in the process of expanding its capacity to 6.3 million ton per annum, around 24MT/annum of bulk materials are to be handled in Visakhapatnam steel plant(VSP). VSP is equipped with peripheral unloading yard for the first time in India to unload the bulk materials in plant premises by transporting by locos, to plant wagon pushers of railways. Raw material plant in VSP is having unloading facilities like rotary wagon tripper, storage yard with machines for stacking and reclaiming and distribution belt conveyor system to feed various raw materials to different process plants by proportioning and by sizing. Thus stackers play a critical role in meeting the demand of bulk material. This project deals with the strengthen of MAST HEAD of twin boom stacker by redesigning to avoid frequent failures.The twin boom stacker is used to stack the raw material in two parallel yards depending on the requirement. The reliability of the twin boom stacker is utmost important for stacking the materials in the storage yard for better logistics. The ageing of twin boom stacker with the prolonged operation resulted in uneven loads or jerks on MAST HEAD. This has resulted in frequent failures of MAST HEAD. The design modification has been verified by modeling the MAST HEAD using SOLIDWORKS Version 2012 and analyzed using FEM package ANSYS 14.5. The Necessary stress strengthening has been made based on the preliminary analysis by increasing the thickness of the spacer and observed that the stresses are within the tolerable limits and are discussed in the topic RESULTS. Thus the design has been frozen and the fabricated drawing has been released for implementation.
