Abstract
Solid particles, such as medicinal preparations, are tested for resilience in a fluidizing apparatus. The test of this invention has several applications, such as predicting abrasion loss for particles which are to be coated in a fluidized bed coating operation, estimating abrasion loss for particles during shipping, and predicting disintegration rate of particles in fluids.
