3T/H DR-28 Ring Roller Mill Calcium Carbonate Grinding Plant Expansion in Minya, Egypt, 2026
Project Overview
Following the successful operation of the previously installed calcium carbonate grinding plant in Minya, Daswell Powder Tech. supplied an additional DR-28 ring roller grinding plant for the same customer once again.
On March 10, 2026, the new system was installed and commissioned at the customer’s other production site. It continues the long-term cooperation between Daswell Powder and this calcium carbonate powder producer in Egypt.
Project Information
As the third largest ground calcium carbonate (GCC) producer in Egypt, the customer continues to expand their production capacity to meet increasing demand for ultrafine calcium carbonate powder in the local and international markets.
The project is designed to process calcium carbonate raw materials and produce ultrafine GCC powder with a fineness of D97 = 10μm, achieving a production capacity of 3 t/h.
Since the beginning of cooperation in 2015, the customer has continuously expanded their production capacity with Daswell Powder equipment and has now purchased six grinding systems, including four DR-28 ring roller mills installed across multiple production sites.
Ring Roller Grinding Process
Feeding → Grinding (DR-28 Ring Roller Mill) → Dust Collection → Pneumatic Conveying → Product Silo → Automatic Packing
This compact system ensures stable operation, low energy consumption, and continuous powder production.
Feeding
The raw calcium carbonate is fed evenly into the system to ensure continuous and stable operation.
Grinding
Then the material enters the DR-28 ring roller grinding mill, where high-pressure grinding rollers and rings generate strong grinding force to produce ultrafine powder.
The mill is equipped with a built-in classifier, ensuring precise particle size control of the final GCC powder.
Packing
Finally, the ground powder is collected by the dust collection system and transported through a pneumatic conveying system to the finished product silo for storage and automatic bagging.
