1,000,000 TPY Ground Calcium Carbonate Grinding Production Line in Jiangxi
Core Equipment：6 sets of GK2150 Raymond Mill
Processed Materials：Calcium Carbonate (≤30 mm)
Production Output：30 t/h (per unit)
Powder Fineness：325 mesh
During the early stage of the project, Guilin Mining Machinery carried out extensive tests on the materials and finally finalized a parallel scheme with 6 sets of GK Raymond mills. Since commissioning, the equipment has been operating extremely stably. Both output and fineness fully meet the targets. The communication throughout the cooperation was smooth with great tacit understanding between both parties.

Project Overview
A calcium industry group in Jiangxi boasts mine reserves exceeding 11.3 million tons with a 30-year mining right. Its mineral powder plant covers an area of over 30,000 ㎡, and the building floor area exceeds 10,000 ㎡. To convert its abundant mineral resources into an industrial chain, the group planned and built this modern heavy calcium carbonate production base with a million-ton annual output. For the core section of this million-ton project, a design scheme of six GK2150 Raymond mills from Guilin Mining Machinery operating in parallel is adopted. Large-scale and intensive production consolidates the customer’s position as a core supplier in Jiangxi’s heavy calcium industrial chain.
Project Details
The process adopts six GK2150 Raymond mills running in parallel. Calcium carbonate materials are cooled in intermediate cooling silos, then fed into each Raymond mill for grinding via feeders. The ground powder is transported by directional airflow generated by fans to classifiers. Precise parameter control ensures the heavy calcium carbonate powder steadily reaches the 325-mesh standard.
Cyclone collectors serve as the primary collection unit to separate and capture most fine heavy calcium carbonate powder. Pulse baghouse dust collectors act as secondary collection and environmental protection equipment to guarantee compliant exhaust emissions and recover ultra-fine heavy calcium carbonate powder. The collected finished heavy calcium carbonate powder is then hermetically conveyed to finished product silos by fully sealed screw conveyors and elevators.
Project Advantages
Large-scale Production: The powerful configuration of six parallel GK2150 Raymond mills delivers a single-machine output of up to 30 t/h.
Stability & High Efficiency: Each GK2150 Raymond mill enables precise control of finished powder fineness, ensuring uniform particle size distribution of 325-mesh heavy calcium carbonate powder and meeting the demand for mass high-standard supply.
Intelligent Control: The centralized control system realizes intelligent linkage and monitoring for the six main mills and all auxiliary equipment across the line, greatly improving management efficiency.
