modules have been volumetric, but the Spectroflex V makes a gravimetric dosing module available. It uses the same base and exchange modules as the volumetric options and is also suitable for granules, regrind, powder and flakes.
Depending on the feed material and the unit
version, thoughputs of between 0.7 to more than 3,000 litres/h are possible with tight dosing tolerances. Free-flowing and non-free-flowing materials can be handled.
“Due to the same technical basis of the volumet- ric and graviteric systems, little training is required for production or to switch between materials and the two dosing technologies,” the company claims. Use of exchange modules also eliminates the need for the system to be stopped
for cleaning during material changes. As a consequence, modification of the set-up is said to be quick and easy. The Spectroflex V gravimetric
dosing unit is controlled via Motan- Colotronic’s Gravinet SF system, which
provides network-compatible control for up to two dosing modules. The company says the DMS load cells are equipped with separate CAN-bus interfaces.

‘Clever’ controllers Motan-Colortronic has also been upgrading various modules for its conveying, drying, dosing and mixing equipment, adding what it describes as “clever” functions and improving lifetimes. One example is the Metroconnect U/C manual coupling station for its vacuum conveying systems, which provides what the company says is a cost-effective entry into central material supply. It is claimed to be easy to use, safe and reliable, even when asked to handle difficult materials. There are two versions, one uncoded and the other coded with RFID technology.

Pipework is usually manufactured in stainless
steel, but Motan-Colortronic now also offers specially hardened, surface- treated distribution branches
that have been designed for conveying particularly abrasive materials such as fibre rein- forced granules. These are also suitable for problematic recycling materials. The company has also upgraded its control software. The LINKnet 3.0 system, which handles system
utilisation and recipe management, includes functions such as provision of process data and archiving for subsequent systems. Its modular structure enables it to be extended for the implementation of specific customer requirements at any time. Finally, the company highlights its new ALARMc-
ollector, which it says provides a simple and cost-effective way to centrally display alarms in the system. “In addition to the ease of use and setup of the digital display of alarms, the new ALARMcollec- tor boasts a sleek design and user-friendly inter- face,” the company claims. Alarm outputs can be directed to any Internet-enabled device.
Mixing in bulk Coperion’s latest mechanical bulk material mixer is the Mix-A-Lot, which it offers as an optional addition to its compounding plants and manufactures in three sizes for throughput rates up to 5 tonnes/h. The unit is said to ensure particularly efficient, high-speed and gentle homogenisation of the fed material. The company adds that an optimised rotor design leads to good mixing performance and short mixing times, which means very little particle
