Abstract
A tacky substance such as a chewing gum base is formed into a compact body. The tacky substance is first comminuted within a bed consisting of a powdered solid, such as a bulking agent, turbulently suspended within a gaseous medium at room temperature. The tacky substance is subjected to repeated mechanical impact within the powdered solid to pulverize it into particles which are then immediately coated by the powdered solid in order to prevent cohesion between the particles. The coated particles are classified to identify those suitable for tableting and the suitable particles are then fed into a tablet press to form a compact body.
