Moretto’s One Wire 6 system is said to adapt automatically to simplify set-up


directly into the main material to overcome colour separation. Features include touch screen control for programming and production tracking.


Germany’s Koch Technik has


added dual load cell technology to its gravimetric blending product line. The company says the use of two synchronous precision load cells further improves the


continuity and precision of the weighing process. It says each fi lling is weighed one hundred times in succession using the dual weigh unit, which registers the values and transfers them to the control unit where compensation can be made for any fl uctuations. The dosed batch is not released into the mixer until the values match.


Graviko blenders use the company’s Mcm-g Touch unit to control dosage values. All dosing parameters are set and monitored via the touch screen graphic interface and, once the recipe has been entered, dosing takes place from the fi rst cycle without the need for calibration. The system includes options for saving programs and recipes, and incorporates control for the hopper loader and blower where the unit is not being used as part of central material conveying system.


The Graviko range covers throughputs from 3 – 2,000

kg/h. The new product line was introduced at K last year, where the company showed the 70 kg/h GK65 version. This weighs up to three material components alongside the main component in basic version. Italy’s Moretto has developed a self-adaptive


conveying system control claimed to offer fully auto- matic set-up. The One Wire 6 system is claimed to be able to recognise any change in the system confi gura- tion and automatically adapt to suit. The company says the One Wire 6 server can manage up to 80 clients (receivers, suction units and automatic manifolds) while


its simple system modularity makes initial installation and subsequent expansion a straightforward task. The system is also pre-pro- grammed to work with the Moretto KruiseKontrol system, which regulates the vacuum conveying speed of pellets and granules and


optimises transport parameters to reduce the risk of angel hair and fi nes.


Moretto has also updated its Kasko


range of vacuum receivers, integrating the electrical control cabling into a metal profi le to protect it from damage. The new models retain the self-adaptive setting features of the original version, as well as the vortex fl ow arrangement that the company claims


enables some 30% more conveying capacity than its alternatives. Also new is the FC range of cyclone fi lters, which are said to require no cleaning and provide a fi ltration performance to 0.5 microns.


Dust and fi nes can present a real problem in injection moulding applications, especially when processing transparent materials. The latest C-20 de-duster unit from Pelletron is designed specifi cally for injection moulding applications, fi tting between the machine throat and hopper where it adds just 240mm of additional height.


The company says the compact C-20 unit provides the same cleaning performance as its larger P1 unit, but consumes just 3.4-5.0 m3/h compressed air at 1.5


– 2.0 bar pressure. The unit provides a nominal product fl ow rate of around 20 kg/h at 560 kg/m³ bulk density, with fl ow rates up to 30kg/h possible for product with higher bulk densities. Features of the C-29 include an integrated agitator


in the throat to prevent bridging and a venturi designed to maximise dust removal and minimise carry-over of good product into the dust collector. It operates with compressed air supplied directly from the plant supply. An ionizer is used to improve release of the electrostatic bond between dust and pellet.
