100,000 T/Y Calcium Carbonate Grinding Production Line in Zhejiang

Project Overview

A large new materials enterprise in Zhejiang required the construction of a modern calcium carbonate grinding production line to achieve efficient, stable, and large-scale production of 325 mesh calcium carbonate powder. After comprehensive evaluation, the client ultimately selected the CRRM1620 Raymond Mill from Cronus Machinery, adopting a "jaw crusher pre-crushing + Raymond mill main grinding" process. This stably produces 325 mesh calcium carbonate powder with a high output of 19 t/h.

Project Details

Calcium Carbonate Mineral → Jaw Crusher → Bucket Elevator → Storage Hopper → Belt Feeder → Raymond Mill

Large calcium carbonate mineral blocks are first crushed by the jaw crusher. Subsequently, they are vertically conveyed by the bucket elevator to the storage hopper, then fed into the CRRM1620 Raymond Mill via the belt feeder for grinding and pulverization. Fine selection is completed through a closed-circuit classification system. Unqualified coarse calcium carbonate powder falls back into the grinding chamber for re-grinding.

Airslide Conveyo → Cyclone Collector → Calcium Carbonate Powder

While qualified 325 mesh calcium carbonate fine powder is carried by the airflow through the airslide conveyo the cyclone collector, where it is separated and collected.

Project Advantages

High-Efficiency Production: The adopted "jaw crusher pre-crushing + closed-circuit grinding" process ensures stable and efficient system operation, with an annual production capacity of up to 100,000 tons.

Reliable Operation: The core grinding components of the CRRM1620 Raymond Mill are made of high-wear-resistant alloy material, offering long service life and low failure rate.

Excellent Product Quality: The finished calcium carbonate powder stably achieves 325 mesh fineness, with uniform particle size distribution, high whiteness, and low impurity content.
