Hazel Aragón Carlos Aragón Bárbara Miranda-Morales Farid Raziel Sanabria-Sandí Ingeniería Biomass crusher grinding mill circular economy particle reduction This article provides an overview of the characterization and construction of a low-cost compact hammer mill for laboratory use to homogenize natural fibers of Elaeis guineensis and Acrocomia sp., in order to reduce the particle size of these fibers and other materials to study their physicochemical properties. The hammer mill was characterized by determining the theoretical output angular velocity in the rotor, the energy required per unit of mass during grinding (kJ/kg), the rotational speed of the rotor with its respective uncertainty extended to 95 %, the calculation of the stress and the safety factor in the rotor and hammers, the resulting particle size of the empty bunch of fruit oil palm (Elaeis guineensis) and the nutshell of the macaw fruit palm (Acrocomia sp.). The hammer mill was built with materials that can be obtained in an industrial hardware store, and a recycled vehicle part. The construction methodology was based on precision machining and metalworking. Residual lignocellulosic materials, such as the empty fruit oil palm cluster, the nutshell of the macaw fruit palm, rocks, coconut shell, wood, sludge, and aluminum slag were ground using this device. The construction of the hammer mill is compact and versatile, and it allows grinding a wide variety of materials for research processes that require the reduction of organic and inorganic materials. Due to its modest size, it can be placed in a laboratory, and since its powered by 110 V, no special requirements are necessary. 2023 artículo científico 1409-2441 https://www.redalyc.org/articulo.oa?id=44174486008 https://www.redalyc.org/journal/441/44174486008/ https://www.redalyc.org/journal/441/44174486008/html/ https://www.redalyc.org/journal/441/44174486008/44174486008.epub https://www.redalyc.org/journal/441/44174486008/movil en http://www.redalyc.org/revista.oa?id=441 Ingeniería.
