摘      要：The production of biomass pellets and briquettes from agroforestry residues has increased rapidly in recent years. The design of machines, equipment and the infrastructure necessary for the handling, trans port and storage of these products has been an engineering challenge since, when moving, biomass does not usually flow as easily as other granular materials. The discrete element method （DEM） provides a means of studying the handling and silo discharge behaviour of granular solids as well as the distribution of the pressures exerted by such materials in silos. However, the development of such models requires certain properties of the particles in question to be known. The present work experimentally determines the true density, Young＇s modulus of elasticity （axial and radial）, the particleparticle restitution coeffi cient and the particlewall friction coefficientall variables that must be known in the construction of DEM modelsfor briquettes made from maize stalk, maize stalk plus pine wood chips, rice husk, vine shoots, raoe straw, cereal straw and sawdust olus cereal straw.
