100,000 TPY Calcium Carbonate Grinding Production Line in Zhejiang

Project Overview

To meet the demands of the high-end market, a large new material enterprise in Zhejiang planned to build a modern calcium carbonate grinding production line, which is required to stably produce 325-mesh high-purity heavy calcium powder. After multiple rounds of comparison and comprehensive evaluation, the customer finally adopted the GK1620 Raymond mill from Guilin Mining Machinery. After commissioning, the equipment can steadily output high-quality 325-mesh calcium carbonate powder with an actual output of up to 19 t/h, meeting the standard for large-scale production of 100,000 tons per year.

Project Details

Large lumps of calcium carbonate mineral are firstly subjected to primary crushing by a jaw crusher, then vertically conveyed by an elevator into a storage hopper for buffer storage. The material is fed uniformly and quantitatively into the GK1620 Raymond mill for grinding and particle size classification via a belt conveyor.

Calcium carbonate fine powder meeting the 325-mesh standard flows with airflow into the dust collection system. After separation and collection by the cyclone collector and purification by the pulse baghouse dust collector, the finished powder is hermetically transported to the finished product silo through air slides, and finally packaged and stored in warehouse.

Project Advantages

Reliable Operation: The core grinding parts of the GK1620 Raymond mill are made of high-wear-resistant alloy material, featuring long service life and low failure rate to satisfy the requirement of long-term continuous production.

Premium Finished Product: The finished calcium carbonate powder steadily reaches 325 mesh with uniform particle size distribution, high whiteness and few impurities, fully complying with application standards for high-end new materials.

Eco-friendly & Clean: The whole process adopts hermetic conveying by air slides and high-efficiency dust removal system without dust leakage. The clean production environment meets environmental protection requirements.
