CLIRIK Machinery’s HGM ultrafine grinding mill is typically suitable for processing eggshell powder within a fineness range of 5 to 74 microns (200-2500 mesh).
The process of using HGM ultrafine grinding mills to turn eggshells into valuable resources involves the following steps:
1. Preliminary Treatment of Eggshells
►Cleaning: The collected eggshells need to be thoroughly cleaned to remove any remaining egg whites, yolks, and other impurities.
►Drying: After cleaning, the eggshells should be air-dried or dried using drying equipment to ensure they are completely dry inside and out, making them ready for further crushing.
2. Coarse Crushing of Eggshells
►Initial Crushing: Crush dried eggshells into particles (<20mm) using coarse crushing equipment or a general crusher to facilitate subsequent ultrafine grinding.
3. Ultrafine Grinding with HGM Mills
►Feeding: The coarsely crushed eggshell particles are fed into the HGM ultrafine grinding mill through a feeding device.
►Ultrafine Grinding: Inside the HGM mill, the eggshell particles are repeatedly ground and crushed between the grinding rollers and rings, ultimately achieving ultrafine particles at the micron or nanometer scale.
►Classification and Collection: The mill’s classifier auto-separates qualified powder, recycles unqualified particles for regrinding, and collects final product in a dedicated system.

4. Applications of Ultrafine Eggshell Powder
►Agricultural Use: Ultrafine eggshell powder can be used as an efficient calcium fertilizer, directly applied to the soil to increase calcium content and promote crop growth.
►Food Additives: After further processing and testing, the ultrafine eggshell powder can be used in the food industry as a calcium supplement added to various foods.
►Pharmaceutical Field: The ultrafine eggshell powder can also be used in pharmaceuticals as a calcium supplement or as a carrier for other drug ingredients.
5. Quality Control and Packaging
Quality Testing: Powder is tested for purity, particle size, and compliance before packaging.
Packaging: Packaged for specific applications, with proper storage/transport.
Value Creation: HGM mill transforms eggshells into high-value additives, enabling resource recycling and eco-benefits.
How does it cost?
The cost of using an HGM ultrafine grinding mill to process eggshells can vary depending on several factors:
1. Equipment Costs
HGM Ultrafine Grinding Mill: The price of an HGM ultrafine grinding mill can range from $20,000 to $200,000 or more, depending on the model, capacity, and features.
Supporting Equipment: Additional costs might include feeders, classifiers, dust collectors, and packaging machines, which can add another $10,000 to $50,000.
2. Operational Costs
Energy Consumption: The power consumption of an HGM ultrafine mill varies depending on its capacity, typically ranging from 30 to 150 kWh. The cost of electricity will depend on local rates.
Maintenance: Regular maintenance, including wear parts replacement (such as grinding rollers and rings), can add to the operational costs.
Labor: Operating the mill requires skilled labor, and labor costs will vary based on local wages.
3. Raw Material Costs
Eggshell Collection: Sourcing eggshells externally (e.g., food processors) incurs raw material costs, which may be minimal when recycling waste.
Pre-processing Costs: Cleaning, drying, and initial crushing of eggshells might involve additional labor and energy costs.
4. Processing Scale
Small-Scale Production: If you’re processing a small volume of eggshells, the overall costs will be lower, but the cost per unit of processed material will be higher.
Large-Scale Production: Scaling up production can reduce the cost per unit, but initial capital investments will be higher.
5. Location and Logistics
Transportation Costs: Moving raw eggshells to the processing facility and transporting finished products to customers can also impact costs.
Regulatory Compliance: Depending on your location, there may be costs associated with meeting environmental regulations, waste disposal, and other legal requirements.
6. Product Value
Market Price of Processed Eggshell Powder: The revenue generated from selling ultrafine eggshell powder will depend on the market demand and pricing, which varies by application (e.g., agricultural, food, pharmaceutical).
Overall Estimate:
Initial setup costs range from 50kto-300k+, with variable operational costs by production scale. Profitability hinges on pricing eggshell powder to cover costs and ensure margins.
