Granulators with New Digital Control System

Hellweg granulators with new digital smart control systems

Hellweg introduces granulators with new digital smart control systems. This enables networked communication of the machines with upstream and downstream components, as well as with operators, in line with Industry 4.0 Internet of Things (IoT) principles.

The new system measures and stores power consumption as well as, for example, rotational speed and bearing temperatures and monitors the service life of bearings, blades, screens, and the wedge-profile drive belts (V-belts). This new smart control system is available for all Hellweg granulators from the 150 series upwards.

Monitoring of mechanical mill components means conclusions can be drawn about expected maintenance dates in order to avoid unplanned production down-time, while possible faults and damage can be detected at an early stage. A visual alarm informs the operator of the need to replace a part due to wear. An active V-belt monitoring system automatically switches off the granulator in the event of a deviation from the nominal value. Smart control also includes an automated enquiry system that issues requests for quotations for spare parts such as blades, screens, and V-belts directly from the manufacturer.

The new “boost operation” option enables a short-term increase in grinding performance, in order to compensate for production-related fluctuations. In addition, certain rotational speed ranges have been defined for various plastics, thanks to which, for example, low melt-temperature granulation can be performed continuously without problems arising, so that water-cooling is not required.
