Motan Gravimetric Dosing Systems

• Dosing up to 6 materials with high accuracy and repeatability.
• Offers excellent mixing quality and consistently accurate dosing, when combining virgin material with additives and diminished material at the processing machine.
• Dosing way: Batch type with high accuracy and repeatability.
• This system can be mounted either directly on to the main extruder or on to the prop body (at the side of the machine).
• In the mixing chamber, that is down under the main body of the machine weighed batches are mixed homogenously.
• All the surfaces that contact the raw material are made of stainless steel.
• Guaranteed exceptionally high accuracy and self-calibration by self-optimization system against any kind of problem that may occur during the process.
• Full PLC Control Units have the touch-screen buttons and are easy to use.
• All dosing stations have sight glasses that enable you to check the raw material level during the process.
• Designed to be easy to clean and maintain with its replaceable raw material tanks.
• It is possible to save more than one material recipe to the PLC Control Unit's memory and set values can be chosen for precise dosing at any stage of the process.
• The actual metered and weighed amounts are constantly checked and transferred to a mixing channel.
• This guarantees exceptionally high accuracy of less than 0.1% by continuous self-optimization.
• Quality control can be made at the production line by connecting a printer to the control system and output data can be attached to the products' transportation papers. In this way you can approve your system's quality and accuracy for customers and also corroborate your quality parameters.
• You can assemble PLC Control Unit on the machine's main body or you can choose the remote control option. However it assembles on the machine's body in standard models.

• Calibration is not required. Adjusts the material proportion automatically and regularly by itself while the process goes on.
• Offers the opportunity to expand the number of its components by in its modular design.
• With its special design Control Unit, vibration and other factors don't affect the system.
• Provides excellent mixing quality and consistently accurate dosing.
• All the machines are of high quality and made from stainless steel. Ergonomic sight glasses that provide control the material flowing while dosing and blending are in progress.
• Formation of lumps or lack of fluidity capacity that can frequently be caused by plate and film breakings (for flake materials) can be avoided by use of Cone Valves at the dosing stations.
• Provides perfect fluidity without any problem
• Intelligent and user-friendly special control units, easy to use and maintain

System Working

Mixer Weigh bin Taper dosing Closing pipe Main component Additive Closing pipe Mixing chamber Sensor

The sensor (9) signals the need for material. The main component (5) arrives in the weigh bin (2) via a pneumatically controlled cone valve (4).

The additive or master batch (6) is added by a pneumatically controlled cone valve (7). Over There, the precisely dosed granulate falls in the weigh bin. The same applies to component (3) or (4) (if any).

After all the components have been added, the cylinder (3) opens the weigh bin, and the material reaches the mixing chamber (8). In the mixing chamber three weighed batches are always mixed at a time.

Motan GRAVICOLOR series brings the blending systems which are designed to use gravimetric material dosing and mixing technology.
