Dosing Systems for Accurate Recipe Control
Product quality in fertilizer, chemical and blending plants is decided at the dosing step: every component must enter the recipe at the right rate. Pro Makina builds gravimetric dosing systems — micro dosing for additives, macro dosing for main components — with weighing technology and automation integrated.

Micro and Macro Dosing
Macro dosing handles the main recipe components — typically from silos or bunkers via weigh belt feeders or loss-in-weight screws at rates of tonnes per hour. Micro dosing adds the small but critical ingredients: trace elements, additives, colourants — where a small absolute error is a large relative one, demanding fine screws and precise load cells.
Both worlds meet in the recipe control system: setpoints per component, tolerance monitoring, batch reports. We deliver the mechanical dosing units, the weighing electronics and the PLC recipe logic as one system, so accuracy is a commitment rather than a hope.

Recipe automation
PLC-based recipe management, tolerance alarms and reporting.
Silo integration
Discharge aids and feeding equipment matched to the storage above.
Data Required for Dosing System Design
| Design input | Role in the design |
|---|---|
| Recipe components and rates | Feeder types and sizes per component |
| Required accuracy per component | Weighing technology selection |
| Batch or continuous process | Feeder control mode and buffer design |
| Material flow properties | Discharge aids and anti-bridging measures |
Dosing accuracy is stated per component in the proposal, based on the selected weighing principle and your material's flowability.
Why Pro Makina
Manufactured in Turkey
Design and fabrication are carried out in our own facility in Eskişehir, Turkey, with full in-house engineering control.
Project-based engineering
Every machine is sized around your raw material, moisture content and capacity target — not sold from a fixed catalogue.
Export experience
We prepare international technical proposals, shipping documentation and commissioning support for overseas projects.
Single point of responsibility
Process design, fabrication, automation and commissioning are managed by one engineering team.
Frequently Asked Questions
What accuracy can gravimetric dosing achieve?
It depends on the feeder principle and the material; loss-in-weight and belt weighing systems achieve recipe-grade accuracy for fertilizer and chemical blending. Exact tolerances are committed per component in the proposal.
Can dosing be integrated with existing plant control?
Yes. Our dosing PLCs exchange setpoints and reports with existing SCADA or ERP systems over standard industrial protocols.
