摘要：This paper proposes on existing problem in performance of wet grinder industry, which can be reduced.The investigation was carried out in wet grinder industry on customer complaint for the quality attainment of wetgrinder. Quality tools like Pareto diagram and cause & effect diagram are used to identify the problem area andcauses. The major problem is longer grinding time, which leads to more energy consumption and higher torque. Theaim of this paper is mathematically describe the design of the shell and identify the factor which affects them. Thegrinding energy of wet grinder is calculated and it is reduced by modifying the existing design. The grinding energyof existing design which has been reduced from 520Joules to 432.5Joules.The performance of grinder has improvedby the reduction of diameter from 300mm to 250mm, which leads to reduction of twisting force from 3000N-mm to2500N-mm using modified design. With the help of Ans ys software, displacement of the shell is arrested andtwisting force of 2500N-mm is applied over the shell along with pre-stressed force 100N for all parts and found thatthe design is safe by matching operating frequency and obtained frequency.
