The present work consisted in designing a pelletizing machine for the production of animal feed from sweet mesquite. designof responded to request clients, consisting small with productivity 640 kg day⁻¹in 8 hoursof work. During design, corresponding resistance calculations, sizing and selection appropriate materials forthe structure other systems that make up were made, such as: transmission s...

The corn crop is one of the most important crops worldwide. However, management residues generated not efficient enough, which diminishes competitiveness this crop. An interesting option for valorization these wastes their thermal use. In order to make residue as much possible, it vital know different processes related a harvest, and try adapt use waste depending on its characteristics. Thus, i...

The production of highly reactive oxygen carrier particles based on low-cost iron materials is explored for chemical looping processes. Ten different Fe-based in the micronized size, both minerals and industrial residues, have been tested as precursors particles. redox reactivity each evaluated compared to state-of-the art with particulate materials, including one new material introduced this w...

Pelletizing and torrefaction increase biomass energy density, generating a more homogeneous fuel with lower moisture, enabling it to burn in equipment high efficiency. This work evaluated the quality of pellets made from wood particles that had been densified torrefied an extruder-type system. Particles Pinus sp. were at 200, 250, 300 °C for six minutes then compacted produce pellets. The physi...

Over ten million tonnes of solid residues are generated yearly from coffee agro-industry worldwide, along with larger amounts of wastewaters and cultivation residues. Both wastewaters and solid residues, such as defective coffee beans and spent coffee grounds, along with coffee husks (pulp and mucilage) that constitute around 60% of the wet weight of the fresh fruit, represent a relevant source...

In iron ore pelletizing plants a range of process parameters such as particle size distribution, specific surface area, and moisture, must be controlled to achieve optimized operation conditions. Particle size distribution and specific surface area are controlled during the grinding operations. Moisture, however, is controlled during filtration of the ground products. This work investigates the...
