We generalize kinetic theory of inelastic spheres to uniaxial, nonspherical grains by including the orientational tensor as a state variable. The theory has three phenomenological parameters, with one parameter to account for the dependency of the stresses on the orientation, which is exactly one for frictionless cylinders, and the other two parameters to predict the orientational tensor.
