Liquid Calcium Chloride Production Equipment
Core Equipment Overview
This integrated production line is specifically engineered for calcium chloride manufacturing, leveraging reactions between hydrochloric acid and raw materials like limestone, calcium oxide, and high-calcium stone. It automates the entire process from reaction, filtration, pH adjustment to concentration, enabling stable production of qualified calcium chloride solutions with a Baume degree of 28-35, perfectly suited for large-scale industrial applications.
Applicable Raw Material Range

Raw Material Type |
Specification Requirements |
Reference Proportion |
| Hydrochloric Acid | Concentration 20%-31% | 2T (30% concentration) |
| Limestone | Calcium content 80%-90% | 1T |
| Calcium Oxide | Purity ≥90% | Replace limestone as needed |
| High-calcium Stone | Calcium content ≥85% | Can replace limestone |
Equipment Working Principle
The system operates on acid-base neutralization chemistry, where hydrochloric acid reacts with carbonates and oxides to form calcium chloride solution. Impurities are removed through solid-liquid separation, followed by pH adjustment to ensure product stability.
