The advantages of vertical grinding mills in processing fluorite
High grinding efficiency and low energy consumption
Adopting the principle of material bed grinding, it has a high energy utilization rate and saves 30% to 50% of electricity compared with ball mills.
The product is flexible in adjustment and has a narrow particle size distribution
By adjusting the rotational speed and air volume of the powder separator, the fineness of the product can be regulated within the range of 80 to 600 mesh, ensuring uniform particle size.
The integrated drying capacity is strong
It is equipped with a built-in drying function, and the moisture content of the feed material can reach 5% to 10%, simplifying the process flow and improving production efficiency.
It occupies a small area and has low noise
Vertical structure, compact system, occupies about 50% less space than the ball mill system, operates smoothly and generates low noise.
Metal loss is small and pollution is minimal
The grinding rollers and grinding discs do not come into direct contact, resulting in minimal wear, low iron contamination, and maintaining the purity and whiteness of the product.
High degree of automation
Equipped with an advanced automatic control system, it is easy to be centrally controlled, reduces manual intervention, and ensures stable and reliable operation.
The process flow of processing fluorite by vertical grinding mill
Raw material preparation
The raw fluorite ore is crushed by jaw and cone crushers, and its particle size becomes smaller. If the moisture content is high, pre-dry it with a dryer.
Grinding and classification
The crushed and dried fluorite particles are sent to the top of the vertical mill by the elevator into the air-locking feeder, and are evenly sent to the center of the grinding disc. Under the action of centrifugal force on the grinding disc, they move towards the edge and are crushed, sheared and crushed by the grinding rollers. Hot air dries the materials and conveys the fine powder to the classification area. The dynamic powder separator rotates at high speed for separation. Qualified fine powder enters the collection system, while unqualified coarse powder is returned to the grinding disc for re-grinding.
Finished product collection and storage
The airflow carrying qualified fine powder enters the high-efficiency bag filter, where the fine powder is collected as finished products. The collected fluorite powder is conveyed to the finished product storage or packaging by conveying equipment, and the purified exhaust gas is then discharged into the atmosphere.
Precautions for processing fluorite with a vertical grinding mill
In view of the low Mohs hardness of fluorite but the need for high purity, vertical grinding mills should select grinding rollers and discs made of special materials such as high-chromium alloys, and be equipped with high-efficiency dynamic separators to minimize iron contamination and ensure product purity to the greatest extent. During operation, it is necessary to precisely optimize core parameters such as the pressure of the grinding rollers, the rotational speed of the grinding discs, the rotational speed of the powder separator, and the air volume and temperature of the system to achieve efficient and energy-saving grinding. Meanwhile, the entire system must be equipped with reliable dust collection and explosion-proof designs to ensure production safety, environmental protection and compliance with emission standards.
Summary
The vertical grinding mill, with its highly efficient and energy-saving process flow integrating crushing, drying, grinding and classification, optimizes core parameters and adopts special materials. While achieving high-yield and high-purity processing of fluorite, it ensures the safety, environmental protection, stability and reliability of production.
