Abstract

TAVARES, Luís Marcelo M.  and  LIMA, Alfredo da Silva. Célula de carga de impacto na caracterização de materiais para a cominuição. Parte 2: fratura de partículas. Rem: Rev. Esc. Minas [online]. 2006, vol.59, n.2, pp.165-172. ISSN 0370-4467.  http://dx.doi.org/10.1590/S0370-44672006000200005.

Impact load cells are used in calculating important parameters that characterize deformation and fracture behavior of individual particles, which include particle strength, particle fracture energy and particle stiffness. In this second part of the paper the influences of impact velocity and moisture content are analyzed. It is demonstrated that the impact load cells available at LTM/COPPE make it possible to obtain consistent particle fracture data over a wide range of sizes of interest in comminution.

Keywords : impact; particle fracture; comminution.
