Designing Crusher Module of Hammer Mill Using the Ulrich-Eppinger Method to Maximize the Fineness of Coconut Shell and Palm Shell Grinding Results
摘要
Organic briquette could be made of coconut shell and palm tree shell. In the current case, 30% of the briquette feedstock were not properly milled, resulting defects. The identified defective modes were improper fineness or particle size. To address this issue, a study to modify and develop a crusher machine aiming to improve the grinding process and reduce waste material was initiated. The Ulrich-Eppinger method was selected as development framework to solve the development problem. This framework starts from concept development to product architectural and detailed design. The study utilized Altair EDEM simulation to simulate the grinding process. The results showed that the developed grinding machine successfully achieved the desired fineness for coconut shell particles with an average diameter of 0.384 mm. Similarly, the palm shell powder manufactured by this machine produced powder particles with an average diameter of 0.31 mm. These conditions were within the expected particle size of <0.40 mm and could be sieved using a 40 mesh screen.
