What is fluorite? 

Fluorite is also called fluorspar. Its Mohs hardness is only 4, making it easy to crush and process. It has stable chemical properties but is sensitive to acids, so corrosion prevention is required during processing. Fluorite plays an important role in many industrial fields. These fields have high requirements for fluorite powder, requiring ultra-fine powder with a particle size of 325 - 2500 mesh, and strict control over purity and particle size distribution.

Advantages of ultra-fine grinding mill in processing fluorite

It has excellent comprehensive performance and various crushing capabilities. It performs outstandingly in the production of 325 - 2500 mesh powder, with a large crushing ratio and high energy utilization rate. It can process micro-powder with D97≤10μm. Equipped with a forced turbine classification system, it can adjust the fineness of the finished product to meet the needs of industries such as plastics and rubber.

Classification control

The dynamic classifier is crucial. The turbine dynamic classifier, based on the principles of centrifugal force and aerodynamics, accurately separates qualified fine powder, prevents over-grinding, improves production efficiency, and ensures product quality.

Drying pretreatment

When the water content of the raw material is >1%, it needs to be dried. Moisture can affect the grinding efficiency and product quality. Rotary dryers and fluidized bed dryers are commonly used equipment, except for the wet grinding process, whose products need to be dewatered and dried.

Anti-pollution measures

The selection of the lining material in the grinding chamber is crucial. Ceramic materials and polymer materials can avoid metal contamination; air jet mills can prevent oxidation and contamination by using inert gas protection.

Parameter optimization

Reasonably adjusting parameters such as feed particle size, fan air volume/speed, and grinding pressure can improve production efficiency, ensure product quality, and the operational stability of the equipment.

Key points of ultra-fine grinding mill in processing fluorite

Over-crushing

Reasonably control the grinding time and frequency. Reducing the grinding time, adopting intermittent grinding, and increasing the rotational speed of the classifier can reduce over-crushing.

Uneven particle size

Wear of the classifier blades and poor air flow stability can lead to uneven particle size. Regularly checking and replacing the blades, optimizing the air flow pipeline design, and installing an air flow stabilizing device can solve this problem.

Dust collection

The pulse dust collector is combined with a closed pipeline. The pulse dust collector uses filtration and pulse dust cleaning technology to collect dust, and the closed pipeline prevents dust leakage and flying, improving the working environment and reducing environmental pollution.

Wastewater treatment

Suspended solids are removed by sedimentation and filtration, and the pH value is adjusted and fluoride ions are removed by neutralization treatment to achieve up-to-standard discharge and recycling of wastewater, improving the utilization rate of water resources.

Conclusion

Fluorite is widely used in the industrial field and has strict requirements for purity and particle size (325 - 2500 mesh). The ultra-fine grinding mill can accurately control the fineness through the turbine classification system and efficiently process fluorite powder.
