A thermoplastic slab breaking apparatus comprising a housing with a slab receiving aperture and an exit aperture on the base of said housing; a conveyor for conveying a continuous hot melt thermoplastic slab from a hot zone to a cool zone within said housing; a first rotatable slab breaker member comprising a pinwheel or a rigid rod with a plurality of rigid tines projecting radially outward therefrom and positioned in close proximity to the end of the conveyor in the cool zone, wherein the rod axis resides approximately in a plane defined by the conveyed slab and perpendicular to a line defined by the conveyed slab; and an optional second breaker member comprising a rigid rod with a plurality of rigid tines projecting radially outward therefrom and positioned approximately axially parallel and beneath the first slab breaker member; wherein the conveyor continuously transports the slab to the rotating first slab breaker and forces the slab into contact with the rotating tines of the slab breaker whereby the slab fragments into pieces, and wherein the pieces thereafter gravitationally fall downward and contact the optional rotating second breaker member so that the pieces are further fragmented into smaller pieces prior to exiting the housing through the exit aperture.
