Evaluation of Properties of Pellets Made of Swine Manure

This paper deals with assessment of density, moisture content and mechanical properties of pellets made of dry swine manure utilizing pellet production line MGL 200. Pellets were subsequently subjected to compressive loading test. Furthermore, the values obtained were measured by means of device Andilog Stentor 1000 and compression diagrams were plotted. In terms of compressive strength, pellet type 1 showed value of 10.47 MPa; pellet type 2 showed value of 6.24 MPa. Considering the elasticity modulus, pellet type 1 showed value of 122.39 MPa; pellet type 2 showed value of 71.12 MPa. Other observed properties included force necessary for 10% compression strain; force in the first maximum of force-strain curve; force in the inflection point of the force-time curve. Results obtained from compressive loading test provide a basis for innovations in pellet production utilizing materials other than wood biomass.
