Creep Spinel Crushers

Statistical study of compressive creep parameters

· Three stage creep curves of alumina spinel refractories were obtained Nevertheless the present statistical study mainly focused on the primary creep stage Therefore the ruler method was applied to identify the transitions of the three stages the linear part of the curves which corresponds to the secondary stage is determined by a ruler The strain hardening form of the Norton
