Abstract:
The paper deals with evaluation of mechanical properties of pellets made of various types of biomass produced by granulating machine MGL 200. The biomass from agricultural production (corncobs) and landscape maintenance (hay and cane) were used for pellet production. The pellets were submitted to compressive loading test. The compressive loading curves were devised using the values measured with the equipment Andilog Stentor 1000. The paper results provide determination of mechanical properties of pellets. Modulus of elasticity of pellets made of ground corncobs was 52.16 MPa; modulus of elasticity of pellets made of hay was 7.44 MPa; and modulus of elasticity of pellets made of cane was 15.45 MPa. Compressive strength of pellets made of ground corncobs was 3.84 MPa; compressive strength of pellets made of hay was 3.5 MPa; and compressive strength of pellets made of cane was 2.7 MPa. Further observed properties were force at 10% of strain, the force in the first maximum of the force – strain curve, and in the inflection point of the loading curve. The results obtained from compressive loading tests provide foundation for innovations in production and usage of pellets made of other material than wood biomass.
