Diseño y simulación de un molino de cuchillas para el reciclaje de residuos de madera con capacidad de 200 kg/h

Abstract

This research focuses on the conceptualization and computational modeling of a blade shredder with a processing capacity of 200 kg/h, specifically designed for managing wood by-products from industrial and artisanal sources. The development methodology integrated a global technical diagnosis, ranging from raw material characterization and the review of current cutting technologies to the definition of the mill's architecture and the full system's structural calculation. During the design stage, digital modeling tools were employed to examine the mechanical response of components under both static and dynamic stresses. Through these simulations, fatigue parameters, deformation, vibration, and safety factors were validated, ensuring the equipment's physical integrity under real working conditions. Simultaneously, mathematical models were implemented to establish the required motor power, blade kinematics, and the torque necessary to ensure consistent and efficient material fragmentation. Finally, a profitability study was conducted to verify the project's feasibility, examining variables such as supplies, manufacturing methods, and skilled labor. The findings demonstrate that the prototype is technically and financially viable, providing a functional alternative for the recovery of wood waste. This contribution offers a multidisciplinary approach that merges mechanical engineering with operational sustainability.
