Design and Build of Molen Machine Capacity 0.056 m³

Abstract

Molen machine is a tool that helps in the process of mixing cement, water, sand, gravel, and other added materials into cast concrete dough. The small capacity molen machine is designed and made to be able to assist the needs of the community or individuals in the process of mixing cement mixture materials on a small scale, which is usually done manually. making drawings, component manufacturing processes, assembling processes, and the process of testing molen machines by stirring a mixture of cement with other added ingredients. The last process is the improvement process based on the results of the trial process. The product of this final project is the design and prototype of a small capacity molen machine. The specifications of the molen machine that are made are mixing capacity of 0.056 m³, the capacity of the contents of the mixing barrel is 148 liters, the main driving force is a 5.5 HP combustion engine. The transmissions used are pulleys, v-belts, chains, chain gears, and gears to produce a rotation of the stirring barrel of 25-30 rpm. The test results show that the small capacity mixer machine that was made can be used to mix cement with other added ingredients.
