Effect of Sawdust Particle Size on Physical, Mechanical, and Energetic Properties of Pinus durangensis Briquettes

Particle size is a physical property that sometimes limits the quality of briquettes, so it recommended to use different sizes in mixtures for their manufacture. The objective this research was evaluate effect particle sawdust on some physical, mechanical, and energetic properties briquettes made from Pinus durangensis sawdust, as well set ranges within appropriate values found obtain desired values. Three were established (large, medium, small), 10 prepared using percentages each classification. density, volumetric swelling, compressive strength, impact resistance index (IRI), gross calorific value evaluated. For determination optimal mixtures, surface response methodology used under three-factor simplex-lattice model. density range 0.92 1.02 g cm−3 swelling 0.96 3.9%. highest compression 37.01 N mm−1, IRI 53 107%. 19.35 21.63 MJ kg−1. selection increases briquettes.
