the drying closed loop. “We also have an advanced IoT solution with a single router capable of a 5 km wireless range supporting up to around 1,500 devices. This system is particularly easy to install and devel- op. Most systems use a combination of both wifi and Bluetooth connection and some cellular – all these methods have good bandwidth but poor range with the exception of cellular, which can be patchy. The system we use has less bandwidth but excellent coverage. We can connect almost any sensor or gauge to the router
with no wiring. Future developments will include refining our supervisor system to incorporate all the IoT information, plus develop the platform to deliver good

Change version of its FlexWall Plus feeder
Kem is used with injection moulding machines and extruders for the direct colouring of thermoplastic materials. A flange instead of a material hopper is sufficient for installing a colouring unit and for dosing masterbatch into a free-flowing supplied material. All programs required for precise dosing, whether based in the cycle of an injection moulding machine or in accordance with an extruder rotation pulse, are included in the new control system. Control is carried out from a touch screen, which offers a clearly structured menu. The programs are selected and modified from a sensitive touch display. The dosed quantities can be set continu- ously in percentages or seconds. When used with injection moulding machines, the dosing values can be saved in a recipe memory and later recalled. An optionally added filling level and rotation monitoring can provide greater safety in the dosing cycle. The optional network interface also enables the integration of each Kem into an external ERP system. The OPC UA-based communication ensures that the colouring devices will be capable of the upcoming digital transformation in companies. Kem-Touch also has a new dosing motor. This stepper

motor with an epicyclic gear case provides retention torque, precise starting and stopping behaviour, as well as 60% lower energy consumption. Brabender Technologie has developed an easy change version of its FlexWall Plus feeder. The company says that a feeding exchange module enables users to reduce downtime during product changeovers. One module will be in production while the other is being cleaned. This allows further quick product changeovers once the dry and wet cleaning process has been completed. “This smart solution minimises cleaning times, accelerates bulk material changeovers and makes more formula- tions feasible with less equipment,” says Bernhard Hüppmeier, Head of Sales in Germany, Austria and Switzerland. The company says that the FlexWall Plus feeder is an all-purpose loss-in-weight feeder for practi- cally any free-flowing bulk materials, such as powders, pellets or flakes. Its flexible polyurethane hopper features lateral massage paddles, which gently stir the bulk material and ensure mass flow without degradation. Different replaceable screw profiles are used depending on the bulk material handled and the performance range required. The easy change version includes the hopper, screw, screw tube and housing as a single unit. Quick- release clamps secure this unit to the chassis and drive mechanism. They only need to be released to enable any residual bulk material to be removed. Moretto has introduced the DPK, a compact loss-in-weight dosing unit suitable for intermittent or continuous dosing of small quantities of colour or additives into a flow base material that solves the problem of overdosing through precise control. The company says that due to a vibration immunity system, the machine control algorithm and the hopper being removable from the dosing unit, the DPK achieves a dosing accuracy of up to ±0.03%. Moretto has also developed
three new types of mainte- nance hoppers for plastic
granules on processing ma- chines. Made of stainless steel, the company says that the conical TM hoppers guarantee an optimal flow of any material and are suitable for single- and three-phase operation and for
receivers of centralised convey- ing systems. TMC hoppers are
used for the treatment of dried hot materials. Also produced in stainless steel, they have double-wall insula- tion with a removable cone that
