There are many clients want to know our calcium carbonate powder grinding mill case every year. We are full of experience of calcium carbonate powder production line project. Today, about the calcium carbonate powder making, we want to talk with you.

How to Choose Suitable Calcium Carbonate Grinding Mill

Particle Size Requirements: Determine the desired particle size of the final product. Different grinding mills have different capabilities in terms of particle size reduction. For finer particle sizes, you may need a mill with higher grinding efficiency, such as a ball mill or a stirred media mill. If coarser particle sizes are acceptable, a roller mill or a hammer mill could be suitable.

Production Capacity: Consider the required production capacity for your application. Grinding mills have different throughput capacities, which determine how much material they can process within a given time frame. Ensure that the mill you choose can handle your desired production rate.

Energy Efficiency: Energy consumption is an important consideration, both in terms of cost and environmental impact. Look for grinding mills that are known for their energy efficiency. Some mills incorporate advanced technologies, such as ultra fine grinding mill (HGM) or vertical roller mills (CLUM), which can offer improved energy efficiency compared to traditional ball mills.

Maintenance and Operation: Consider the maintenance requirements and ease of operation of the grinding mill. Mills with simple maintenance procedures and user-friendly controls can help minimize downtime and ensure smooth operation.

Cost: Compare the initial investment cost and the operational costs of different grinding mills. Take into account factors such as the purchase price, installation expenses, power consumption, and maintenance costs. Balance the cost considerations with the desired performance and quality requirements.

Expertise and Support: Assess the availability of technical expertise and after-sales support from the mill manufacturer or supplier. It can be beneficial to work with a company that has experience in the field and can provide guidance or troubleshooting assistance if needed.

Test and Trial: If possible, conduct test runs or trials with different grinding mills using representative samples of the calcium carbonate material. This can help you evaluate the performance and suitability of each mill before making a final decision.

For Calcium Carbonate Grinding We Recommend HGM Grinding Mill

HGM grinding mill which is a type of grinding mill designed to process various non-flammable and non-explosive materials with Moh's hardness below 9.3 and humidity below 6%.

The HGM series grinding mills are widely used in industries such as mining, metallurgy, chemical engineering, construction materials, and more. They are capable of grinding materials into fine powders ranging from 325 to 2500 mesh.

Here are some key features and characteristics of HGM grinding mill:

High Grinding Efficiency: HGM grinding mill are equipped with a high-pressure spring system, which can increase the grinding force and improve the grinding efficiency.

Multi-stage Grinding: The HGM grinding mill consists of multiple grinding rollers and grinding rings arranged in a ladder-like structure. This design allows for multiple grinding stages, enhancing the grinding effect and achieving finer particle sizes.

Energy-saving Design: HGM grinding mill are equipped with a frequency conversion system, which adjusts the rotation speed of the main unit and saves energy consumption.

Advanced Classification System: HGM grinding mill are equipped with an efficient classification system that can control the particle size distribution of the final product. This ensures consistent product quality and narrow particle size distribution.

Wide Range of Application: HGM grinding mill can process various materials, including but not limited to limestone, calcite, marble, talc, barite, dolomite, gypsum, graphite, and other non-metallic minerals.

Easy Maintenance: HGM grinding mill are designed for easy maintenance and operation. The wearing parts, such as grinding rollers and grinding rings, can be replaced quickly, and the maintenance requirements are relatively low.

HGM Grinding Mill for High Quality Calcium Carbonate Powder Processing

The HGM grinding mill is indeed suitable for grinding calcium carbonate powder. It can effectively process calcium carbonate materials with various particle sizes and achieve the desired fineness.

Here's how you can use the HGM grinding mill for calcium carbonate powder grinding:

Preparation: Ensure that the calcium carbonate material is properly prepared for grinding. This may involve crushing or pulverizing larger chunks of calcium carbonate into smaller particles, depending on the initial size of the material.

Feeding: Use a feeder or a conveyor to introduce the calcium carbonate material into the HGM grinding mill. The material should be evenly and continuously fed to maintain a stable grinding process.

Grinding: The HGM grinding mill utilizes the high-pressure spring system to apply pressure to the grinding rollers and grinding rings. The material is repeatedly ground and impacted between the rollers and rings, resulting in particle size reduction. The grinding process occurs in multiple stages, with the material being ground finer and finer as it passes through the mill.

Classification: After the grinding process, the calcium carbonate powder needs to be classified to control the particle size distribution. The HGM grinding mill is typically equipped with an efficient classification system, such as a high-precision turbine classifier or an airflow classifier. This system separates the fine particles from the coarser ones and ensures that the final product meets the desired specifications.

Collection: The ground calcium carbonate powder is collected in a cyclone separator or a bag filter. This allows for the separation of the powder from the airflow, ensuring clean operation and preventing the powder from being carried out with the exhaust gas.

Fineness Adjustment: The HGM grinding mill offers the flexibility to adjust the fineness of the calcium carbonate powder. This can be achieved by adjusting the rotational speed of the main unit or changing the gap between the grinding rollers and grinding rings. Fine-tuning the fineness allows for customization according to specific application requirements.

Storage and Packaging: Once the calcium carbonate powder is collected, it can be stored in appropriate containers or packaging for further use or distribution.

Remember to follow the manufacturer's guidelines and recommendations for operating the HGM grinding mill and ensure proper maintenance to achieve optimal performance and longevity of the equipment.

Different Calcium Carbonate Fineness Powder Application

Coarse Calcium Carbonate Powder (100-400 mesh):

Construction Materials: Coarse calcium carbonate powder is often used as a filler in concrete, asphalt, and building materials. It enhances the strength and durability of the materials.
Animal Feed: It can be used as a calcium supplement in animal feed to promote bone development and improve overall animal health.

Medium-Fine Calcium Carbonate Powder (400-800 mesh):

Plastics and Rubber Industry: This fineness range is suitable for adding calcium carbonate as a filler in plastic and rubber products. It improves their strength, rigidity, and dimensional stability.
Paints and Coatings: Medium-fine calcium carbonate powder is used as a pigment extender and filler in paints and coatings, providing improved hiding power, viscosity control, and surface finish.

Fine Calcium Carbonate Powder (800-1500 mesh):

Paper Industry: Fine calcium carbonate powder is widely used in the paper industry as a filler and coating pigment. It improves paper smoothness, opacity, and printability.
Pharmaceuticals: Fine calcium carbonate powder can be used in pharmaceutical formulations as an excipient or active ingredient for antacids and calcium supplements.
