A model of the spherical locked particles of the binary system in which the components are bounded by a spherical surface, was introduced. The equations of the locking factor and the volume ratio of the components were derived for the model. The curves showing the relationship between the locking factor and the volume ratio of the components were drawn for various values of the radius ratio of the components. Moncrief and Lakewood's equation of the locking factor coincides with one of the authors' equations in which the radius ratio of the components is assumed to be infinite. Measurements of the locking factors and of the area ratio of the components were made on the artificially prepared locked particles. It was recognized that the mearured average locking factors turned out to be larger than the theoretically calculated ones. The discrepancy was inferred to be mainly due to the distributions of the volume ratio of the components in the ranges of smaller and larger values in artificial locked particles. The effects of the shape of the components and other factors on the locking factors are briefly discussed.
