Gravimetric dosing & mixing units SPECTROFLEX
SPECTROFLEX is ideally suited for dosing powders, pellets, granulates, regrinds, fibers, and flakes in both continuous and batching processes. motan's unique removable exchange system provides two huge advantages over traditional dosing and mixing designs.
Firstly, the quick exchange hopper enables the user to clean and change materials in less than one minute. Secondly, single and twin screw exchange modules are interchangeable, allowing the user to configure the feeder for nearly any type of material in a matter of minutes.
The massage rollers of the SPECTROFLEX ER are powered by an independent motor and can be set to 48 different positions, guaranteeing you optimum dosing for every material.
Material changeovers are fast and require no tools. The quick exchange hopper enables you without tools to change materials in less than one minute. The complete dosing module can be used as a material cassette, allowing you to change materials without any clean-down.
The gravimetric version sits on an integrated, robust but extremely precise weigh platform and operates using loss-in-weight metering technology. Giving you a high level of operational security as all parameters can be documented and verified.
Single and twin screw hoppers are interchangeable, and there are many different types of dosing screws are available e.g. single, twin, spiral, auger. This allows you to configure the dosing unit for nearly any type of material in a matter of minutes.
The massage rollers eliminate the need for you to use a mechanical agitator and so fragile materials will not be damaged.
The massage roller technology creates an active filling of the dosing screw so that the SPECTROFLEX gives you better dosing than can be achieved with conventional dosing units which use mechanical agitators.
Rotating massage rollers rather paddles are used. The friction free gentle operation of the rotating massage rollers which are always in contact with the polyurethane hopper and do not rub against the wall of the hopper causing wear.
You can install a hopper loader directly onto the extension module of the hopper which does not need to be removed even during material changes.
Because the SPECTROFLEX is controlled by the GRAVInet GP control system, it allows the unit to work as part of a SPECTROPLUS dosing and mixing system. For example, on a compounding line a SPECTROPLUS station may be mounted over the main inlet of an extruder and a SPECTROFLEX unit will be used to dose fillers or reinforcement through a side inlet downstream of the melt.
The GRAVInet GP control system is designed for controlling multiple dosing modules and stations. It boasts an innovative, Ethernet-based open network architecture. In addition, it offers you excellent control characteristics when handling set point jumps and ramp mode thanks to its optimised control settings and filter functions. The high-tech touch screen colour display with LCD-TFT resolution enables simple, intuitive, fast, and reliable operation. It has comprehensive features for process and recipe management, offering you reporting functionality for quality assurance and it delivers advanced service functions and graphical display of process data.
The GRAVInet GP light has the same display and functionality of the GRAVInet GP but can only control up to a maximum of two dosing modules. It offers all the benefits of its big brother but at a lower price.
