Transforming Raw Material into Profitable Products – Calcium Carbonate Grinding and Coating Line Installed in Minya, Egypt

Customer Challenges: Limited Value from Raw Calcium Carbonate

Located in Minya City, Egypt, the customer owned a large deposit of natural calcium carbonate. However, selling unprocessed or coarsely ground material on the market brought only low returns and limited market demand. Without the capability to produce high-grade fine powder, the customer was unable to tap into higher-value downstream industries such as plastics, rubber, coatings, and construction — all of which require finely ground or surface-treated calcium carbonate as functional fillers.

Customer Needs: Upgrade Material, Increase Value
To break out of the commodity trap and increase the profit margin, the customer was seeking a reliable, efficient, and cost-effective grinding solution. The goal was to produce ultra-fine calcium carbonate powder (D97 5–45?m), with part of it coated for applications requiring improved dispersion and surface performance.

Key requirements included:

Stable production of 8–10 micron D97 powder

Surface modification system for added product value

Energy-efficient operation

Easy maintenance and long-term reliability

After evaluating multiple equipment suppliers, the customer connected with Daswell Machinery, attracted by our specialization in non-metallic mineral processing solutions. They appreciated our track record in building turnkey calcium carbonate grinding plants across the Middle East and Asia.

Daswell Solution: Tailored Grinding + Coating System

After careful evaluation of the customer’s material, product goals, and factory layout, Daswell engineers proposed a Grinding Mill and Vortex Mill Coating Machine, capable of producing consistent fine powder with optional surface treatment. The system was designed for high output, minimal downtime, and optimal energy efficiency.

Final Production Line Delivered

The final production line included:

Φ2.2×5.5m Ball Mill – for efficient fine grinding

AMS10003 Air Classifier – for precise particle size control

XMC70-7 Bag Dust Collector – for clean and safe operation

Vortex Mill Coating Machine – for added functionality and product performance

This configuration enables the production of:

D97 10?m powder at 2.8–3.1 tons/hour

D97 8?m powder at 2.2–2.4 tons/hour

Delivery, Installation & Commissioning

Daswell coordinated the entire shipment and installation process, including mechanical setup, electrical wiring, trial runs, and operator training. Our engineers were dispatched to Egypt to ensure smooth commissioning and fine-tuning of the system.

Despite the remote location and multi-stage process, the project was delivered on time and met the performance expectations from the very first test run.

Customer Feedback: “Perfect“

The customer summarized their experience in a single word: “Perfect.”
From equipment quality to on-site service and final product performance, every step matched or exceeded expectations. The new production line has already helped the customer gain access to higher-value clients in filler and polymer-based industries, while boosting their overall profitability.
