the scale and can easily be removed. This has enhanced feeder accessibility – with end users benefiting from faster cleaning of components. Captive quarter-turn fasteners on the screw trough, hopper and lid help to speed up changeover time. Seal replacement is also easier and faster, thanks

relevant material data, as well as process param- eters in order to monitor it. This is where the Motan-Altair demonstrator fits in. Altair provides – through a material database – the necessary data infrastructure and material information, while Motan interconnects the material logistics, includ- ing the machines involved for processing, com- pounding and grinding. For each step, energy consumption is deter- mined and recorded. This data is then fed back to the materials database so it can be analysed and visualised. The database system is an individual version of
Altair’s Material Data Center, in which existing material data is complemented with carbon footprint properties and processing characteristics. By way of an interface to Motan’s Material Data Gateway, it will supply Motan servers with process- ing data and – in return – live information about new and processed batches is returned. This data is displayed and managed in a consolidated location to improve decision making – helping to improve both products and processes.
Kit upgrade Brabender Technologie has upgraded a broad range of its gravimetric feeders The company says that, with ever-smaller lots sizes and faster product changes, feeding equip- ment must be more versatile. It says that its ‘Generation 2.0’ equipment has taken these requirements into account, with a modular concept that allows easy disassembly and accessibility. The principle has been put into action in its
twin-screw DDSR20 2.0 feeder and single-screw DSR28 2.0 feeder. The modular design allows the gearbox on both feeders to be easily changed and replaced. “This flexibility enables the customer to switch between single and twin-screw versions,” said Jürgen Knez, head of product development at Brabender. The screw trough is located at the front end of

to an easy screw trough removal – from the front of the feeder. A new seal can be inserted within five minutes. A new seal change indicator flags up when seals need to be change – at an early stage, which prevents gear and motor damage. In addition, Generation 2.0 units feature dust-tight vertical outlets made of transparent PETG. This is shatter- proof and the transparency allows the operator to perform visual checks of ingredient flow. The feeders are available with an optional servo
motor. This has the added benefit of a wider speed range, with full torque available at low rpm. The need to change screws and screw tubes can now be further reduced, which helps to minimise downtime. At low speeds, servo motors in high torque conditions still allow good speed control, said the company. “The new design has enabled us to start offering customised, purpose-specific feeders that are more effective than before,” said Knez.”
Compact range Moretto of Italy has developed a number of new or improved models in materials handling. Its new Compact range of hopper loaders, containers and receivers claims to be 30% smaller than equivalent products. One example is its Kasko Compact single-phase hopper loader, which is equipped with a two-stage turbine and automatic filter cleaning as standard. Other key points include: quiet performance, soft start and a high efficiency discharge valve with gasket. It has also restyled its three-phase VS Eco suction units to be more compact. The new range can work at a high load capacity and equipped with extra devices – such as vortex filter, bypass valve or cooling ring.
Efficient solution Coperion K-Tron says that its preconfigured ProRate Plus feeders offer an efficient feeding solution. All three sizes of the feeder – small, medium, and large – were on show at K2022. The continuous gravimetric feeder line is an economical solution and offers a quick return on investment due to its good price-performance ratio and fast delivery times, says the company. The feeder line’s design allows a very compact, space-saving arrangement. The trapezoidal shape of
