Cronus Machinery: A Professional Raymond Mill Production Base

On April 13, 2026, the CRRM1850 Raymond mill manufactured by Cronus Machinery passed quality inspection and was shipped to Gansu. With a feed size of ≤30 mm and a capacity ranging from 6.5~30 t/h, the mill is well-suited for high-efficiency limestone processing in Gansu.

In the 6R/5R/4R/3R Raymond mill models, the letter "R" stands for Roller, while the number indicates the performance level rather than the exact number of rollers. More rollers provide a larger grinding area, but factors such as grinding ring diameter also affect equipment performance. Therefore, when selecting a mill model, one should not focus solely on the number of rollers.

An superfine grinding mill is a type of equipment used to grind materials into ultra-fine powder ranging from 400 to 2500 mesh, with some high-end models capable of achieving 3000 mesh or finer. Common types of superfine grinding mills include ultrafine vertical roller mills, ultrafine ring roller mills, jet mills, and ball mill classifier production lines (ball mill + air classifier).

Copper ore grinding mills support both dry and wet processes. For dry grinding, a Raymond mill is selected, equipped with a temperature monitoring and cooling system to prevent sulfide oxidation. For wet grinding processes requiring flotation beneficiation, a wet ball mill is used for coarse grinding, paired with a vertical stirred mill for fine grinding.

Carbon black grinding mills typically adopt an open-circuit process. For conventional 80~400 mesh carbon black powder, an open-circuit Raymond mill is recommended. For ultra-fine carbon black powder above 400 mesh, an open-circuit ultra-fine ring roller mill is recommended.

Safety protection and environmental protection shall be given attention in aluminum dross grinding. For primary aluminum dross grinding, a combination of ball mill and Raymond mill is commonly adopted. For secondary aluminum dross grinding, a vertical roller mill is the preferred choice.
