Partial least squares regression revealed two critical principal components of the granulation rate : one relating to the droplet dimension , which is composed of mist diameter and diameter and thickness of the droplet after adhesion of the binder to the lactose surface ; and the other relating to wettability , which involves the work done during adhesion and cohesion , surface tension , and the thickness of the droplet after adhesion of the binder to the lactose surface .
