Production Process and Equipment for Dry Calcium Carbonate Production

In mineral processing, Heavy Calcium Carbonate plays an irreplaceable role in various fields such as plastics, rubber, papermaking, and coatings due to its excellent physical and chemical properties. This article will provide a detailed introduction to the dry production process flow, characteristics, and key milling equipment for HCC, presenting you with efficient and environmentally friendly solutions for HCC production.

Dry Production Process Flow for Calcium Carbonate

1. Hand-pick raw materials such as calcite, limestone, chalk, and shells transported from quarries to remove gangue.

2. Jaw crushers and impact hammer crushers perform coarse crushing on the raw materials, reducing their particle size to a suitable size for grinding.

3. Raymond mills, ball mills, or vertical mills grind the crushed calcium carbonate, obtaining fine limestone powder.

4. Calcium Carbonate Powder that meets the particle size requirements is packaged and stored, while powder that does not meet the requirements is returned to the mill for re-grinding.

Characteristics of the Dry Production Process for Calcium Carbonate

The dry process eliminates the need for subsequent filtration, drying, and dewatering, resulting in simple operation, easy control, and lower operating costs. Compared to wet production, the dry production process exhibits unparalleled advantages in processing calcium carbonate. It requires no significant water resources, reducing wastewater treatment steps and aligning more closely with current green mining and circular economy development concepts. Through crushing, classification, and grinding, the dry process can precisely control the particle size distribution of the product, meeting the refined requirements of different industries for raw materials. Additionally, dust in the dry production process is effectively collected and treated, ensuring a clean and safe working environment.

Calcium Carbonate Milling Equipment

Raymond Mill: The Raymond mill is one of the most commonly used milling equipment in dry calcium carbonate production, featuring a simple structure, easy operation, and low maintenance costs. It is suitable for producing calcium carbonate products with a particle size of 38-74µm (200-400 mesh). 

Roller Mill: The ring roller mill is an efficient and energy-saving milling equipment suitable for producing calcium carbonate products of various particle sizes. 

Ball Mill: The ball mill is one of the main equipment in large-scale heavy calcium carbonate production lines, suitable for producing calcium carbonate products of various particle sizes. It uses steel balls as grinding media, crushing materials through the impact and friction of the steel balls. The ball mill has the advantages of high grinding efficiency and controllable particle size.

Vertical Mill: It can directly produce calcium carbonate micro-powder products with a particle size of 325-600 mesh and can also be used in combination with other ultrafine grinding equipment to prepare ultrafine calcium carbonate products.
