The new gravimetric dosing units in the Micro range have been designed by Engin Plast for dosing single-component materials in pellet form, using a continuous, real-time, weight loss method to achieve accurate dosing. These units provide the following advantages:
Micro is equipped with a gravimetric hopper based on a load cell that measures changes of weight of additive in real time. The microprocessor uses these data to regulate the speed of rotation of the dosing screw. This type of doser is particularly indicated either for direct feeding of an extruder, or used in combination with the main hopper to mix additives into the main component. Its small size and attractive design make it both economical and aesthetically pleasing.
