Underwater Pelletizing System handles up to 600 kg/h.

Press Release Summary:

Mounted on solid, mobile frame with lockable wheels, SPHERO®50 can be moved, adapted to other extruders, or parked at idle spot when not in use. Design of cutter head ensures production of evenly shaped, quality pellets. All relevant pelletizer components such as start-up valves, die plates, water basins, and drives are suspended from T-bar and can be shifted on bar horizontally. All other system components are mounted to minimize footprint while remaining freely accessible.

Original Press Release:

Broad Range of Applications for the Sphero®50 Underwater Pelletizing System

With the new generation of the proven SPHERO®50 underwater pelletizing system, Automatik Plastics Machinery will present an optimized adaptation of Maag's single components. The SPHERO®50 features a well thought-out design and improved ergonomics. The technical benefits for the customer are quick start-up, permanent process reliability also with difficult products, and an outstanding pellet quality. The operator benefits from the compact design, with all system components mounted on a mobile frame, as well as from free access from all sides. This significantly simplifies the cleaning of the machine and product changeovers.

Broad production range for up to 600 kg/h

The SPHERO®50 with its modifications can be especially applied in testing plants and technical centres but also in smaller production plants with varied pelletizing application options for virgin polymers, masterbatches, compounds, technical plastics, recycling, thermal elastomers, micro-granular compounds, and organic and timber-polymer materials. The SPHERO®50 is capable of handling flow-rates of up to 600kg/h. In economic terms, even significantly lower flow-rates from approximately 70kg/h are already profitable (subject to product). The SPHERO®50 as the smallest system of the SPHERO® series offers the same benefits as the bigger SPHERO® versions thanks to the same functionalities.

"Plug & Play" allows ergonomic space concept

The design of the SPHERO®50 focuses on optimal user-friendliness and maintainability and can virtually be put into operation in a "Plug & Play" manner. The entire system is mounted on a solid, mobile frame with lockable wheels and can be moved easily, adapted to other extruders, or "parked" at an idle spot when not in use. All relevant pelletizer components such as start-up valves, die plates, water basins, and drives are suspended from a T-bar, can be shifted on the bar horizontally, and can be accessed easily. All other system components such as the Centro 50 pellet dryer, the process water system, the hydraulic unit for the start-up valve, and the electric control cabinet with integrated touch panel are mounted to minimize the footprint while remaining freely accessible on the frame. The operator is not hindered by tripping hazards and can easily access the system from any direction. The ergonomic design concept allows easy cleaning and quick changes of die plate, blade carrier, and blades and is the prerequisite for quick product changeovers and reduced downtimes.

Optimized cutting processes - evenly shaped pellets

Special attention was given to the new design of the cutter head in order to ensure the production of evenly shaped, high-quality pellets. Thanks to the reset force-free adaptation of the blades to the die plate, the pellet quality is improved and process reliability is increased. In addition, the characteristics of the pellet flow inside the cutting chamber have been optimized. The benefits both for the operator and the customer are minimized generation of dust with brittle products, reduced wear with fibre-reinforced plastics, and reduced agglutination with thermoplastic elastomers.

Quick product change for Masterbatch Applications

SPHERO®50 fulfils the special requirements of masterbatch applications because it is comfortable to use and important components such as die plate or dryer are easily accessible for cleaning with optimal matching filtration to boot.
