1. What is a gravimetric doser?
A gravimetric doser is an automatic dosing system that measures material by weight rather than volume. Using high-precision load cells and real-time weighing, it accurately controls the feeding rate of masterbatch, plastic granules, and other additives.
2. How Does a Gravimetric Doser Work?
The control system sends a signal to the motor, which drives the dosing screw through a coupling. Masterbatch from the hopper enters the screw and is continuously conveyed to the outlet. A high-precision weighing sensor monitors the material weight in real time, while the control system adjusts the screw speed according to the preset dosing ratio. This enables accurate metering and stable, proportional feeding of masterbatch and other materials.
3. What materials can be dosed with a gravimetric doser?
Mconvey gravimetric dosers are suitable for a wide range of plastic materials, including plastic granules, pellets, masterbatch, color additives, and other granular additives. The dosing system can be configured according to material characteristics and production requirements.
4. What is the difference between a gravimetric doser and a volumetric doser?
A gravimetric doser controls material feeding based on weight, while a volumetric doser controls feeding based on volume. Gravimetric dosing can compensate for changes in material bulk density, making it a suitable choice for applications requiring higher dosing accuracy and consistency.
5. How do I choose the right gravimetric doser model?
The appropriate model depends on factors such as material type, required dosing rate, masterbatch ratio, number of components, hopper capacity, and production line capacity. Mconvey can recommend and configure the suitable gravimetric doser according to your specific production requirements.
