Abstract: Apparatus assembly including continuous particle forming means, such as pelletizer, mounted on mobile platform, adapted to deposit compression formed particles as they are formed substantially throughout a large curing area to permit at least partial hardening of the particles prior to further handling. Preferably, rail mounted longitudinal and transverse supports permit movement of the pellitizer both transversely and longitudinally through predetermined paths. Most preferably, pelletizer is also mounted with elevation means to permit raising and lowering and thereby to control the drop of freshly formed particles and to permit their disposition with minimum drop as inventory of formed particles accumulates.
