Bone powder miller optimization

Abstract

Abstract Bone waste has started to emerging problem worldwide with the rise of meat consumption, thus the further processing of bone waste would help in tackling the problem as the powdered bone itself can be used for various use, from animal feed additive to cement replacement in concrete making. The built bone powder miller has performance of effective capacity of 12.03 kg/hour, 8% damaged product, and 0.35% bone powder moisture, in order to attain better performance, the miller thus optimized through the means of varying drying temperature, sieve hole size, rotation speed and testing several levels of workloads and finally testing various bone material to be powdered. Individual optimization procces was able to show best performance for optimized variables, but has no improvement to miller performance using original setting. the bone miller is expected to be able to alleviate cow bone waste problem and converting it to usable materials in form of bone powder, in turn, contributing to waste reduction while adopting zero waste concept for sustainable agricultural production.
