Short description
Additive dosing systems are used for the controlled and continuous addition of aggregates and additives in industrial process lines. They are particularly employed in the wood, biomass, and pelletizing industries to introduce binders, powders, or granulates into the process in a defined and reproducible manner.
Dosing is carried out volumetrically and is adjusted on the process side to the main mass flow. The systems are designed for continuous operation and can be flexibly integrated into existing plants.
Principle
The additive is fed manually or automatically into the dosing system’s storage hopper. From there, it is conveyed to the actual dosing unit, where it is continuously discharged via a screw feeder.
To ensure a uniform material flow, the dosing unit is equipped with an integrated mixing or agitation device that reliably prevents bridging and blockages.
Dosing is performed volumetrically and is typically controlled proportionally to the mass flow of the main process (e.g. dosing screw or press operation). The control system is integrated into the higher-level process control system.
Design and components
An additive dosing system typically consists of the following assemblies:
Lower section (dosing unit)
Dosing screw with integrated mixing or agitation device
Removable components for maintenance, cleaning, and serviceMittelteil (Vorratsbehälter)
Rohstoffvorlage für Dosiergüter
Sicht- und Serviceöffnungen zur FüllstandskontrolleUpper section (filling and access protection)
Protective grid for manual filling
Designed for safe emptying of bagged material
Prevents access to the dosing area during operation
Process integration
Additive dosing systems are typically used:
- for binder addition in pelletizing and briquetting plants
- for dosing aggregates in biomass processes
- for precise recipe and quality control
Integration typically takes place downstream of raw material preparation and upstream of the pellet press or mixing stage. Synchronous control with the main process is essential to ensure consistent product quality.
