Ultrafine Grinding Mill and Iron Oxide Red

Iron oxide red can be used in fields such as paints, coatings, plastics, and building materials to enhance the color and quality of products. It has strict requirements on processing fineness and purity. Fineness affects dispersibility and uniformity, while purity influences color, chemical stability, and application effects. The ultrafine grinding mill is an ideal equipment for grinding iron oxide red, capable of producing high-quality powder to meet the needs of various industries.

Process of Processing Iron Oxide Red with Ultrafine Grinding Mill

Feeding

Lumpy or granular raw materials are uniformly and accurately fed into the mill by a feeder. The stable operation of the feeder ensures the continuous supply of raw materials.

Crushing

The main machine drives the central spindle to rotate, and the grinding rollers press against the inner wall of the grinding ring under the action of centrifugal force, exerting strong pressure on the raw materials for crushing.

Pulverizing

The raw materials are crushed into fine particles under the action of pressure and shearing force, which improves the grinding efficiency and controls the product granularity.

Classification

The air flow from the fan sends the powder into the classifier. The fine powder with qualified fineness passes through, while the unqualified coarse powder falls back to the grinding disc for re-grinding.

Collection

Cyclone separators and dust collectors collect qualified products with a collection efficiency of over 99.9%. Its "grinding while classifying" closed-circuit circulation system improves production efficiency and reduces energy consumption.

Key Points in Processing Iron Oxide Red with Ultrafine Grinding Mill

Fineness Control

The rotating speed of the classification impeller is the core factor in controlling product fineness. As the rotating speed increases, the centrifugal force increases, resulting in more qualified fine powder. Air volume affects the carrying and residence time of materials. Coordinated adjustment with the rotating speed can precisely control the fineness.

Output and Energy Consumption

The feeding amount should be stable and match the capacity of the mill; too much or too little will affect the output and energy consumption. The rotating speed of the mill needs to be reasonably controlled. Excessively pursuing high rotating speed will increase energy consumption and equipment wear, so the optimal balance between output and energy consumption should be found.

Equipment Maintenance and Anti-pollution

It is recommended to use ceramic materials for wear-resistant parts. Regularly check the wear of grinding rollers and grinding rings and replace them in a timely manner. Lubricate the transmission parts such as the main shaft and bearings on time. Strictly control the moisture, hardness, and impurities of the materials entering the mill to ensure the purity of raw materials.

Summary

Ultrafine grinding mill is an ideal grinding equipment for processing iron oxide red. During processing, attention should be paid to fineness control (with the rotating speed of the classification impeller as the core, coordinated with air volume), balance between output and energy consumption (stable feeding amount and reasonable speed control), and equipment maintenance and anti-pollution (using ceramics for wear-resistant parts, regular maintenance and lubrication, and controlling materials).
