Summary

In 6R/5R/4R/3R Raymond mills, R stands for Roller. The number indicates the performance grade instead of the exact quantity of grinding rollers. More grinding rollers bring a larger grinding area, yet other parameters such as the grinding ring diameter also affect equipment performance. Therefore, you should not only focus on the roller count when selecting the mill.

Naming Rule of R-series Raymond Mill

In the model names of 6R/5R/4R/3R Raymond mills, R stands for Roller, and the number indicates the performance grade rather than the exact number of grinding rollers. For example, 4R3320 Raymond mill is a medium-small type Raymond mill with 3~4 grinding rollers instead of exactly 4 rollers.

Performance Grades of R-series Raymond Mill
3R	4R	5R	6R
Small-sized unit	Medium-small unit	Medium-large unit	Extra-large unit
3~4 rollers	3~4 rollers	4~5 rollers	5~6 rollers

3R Raymond Mill

The 3R Raymond mill is mainly equipped with 3 grinding rollers (a few models with 4 rollers). It is compact and small, covers a small area and is light in weight (4~5t). It features low investment cost and suits small-batch production and projects with limited site space.

4R Raymond Mill

The 4R Raymond mill mainly adopts 4 grinding rollers (a few models with 3 rollers). Compared with the 3R mill, it has a larger grinding area and its capacity increases by roughly 50%~80%. With strong versatility and high cost performance, it fits most medium-small production lines.

5R Raymond Mill

The 5R Raymond mill mainly has 5 grinding rollers (a few models with 4 rollers). It is a medium-large unit. Its grinding area is greatly expanded and its output reaches 1.8~2 times that of the 4R mill. It delivers more uniform powder size and higher screening rate, suitable for large-scale industrial production with fineness requirements.

6R Raymond Mill

The 6R Raymond mill is mainly fitted with 6 grinding rollers (a few models with 5 rollers). It has high grinding efficiency and large single output above 10 tons per hour. Although the initial investment is higher, its unit energy consumption is lower than small Raymond mills, making it ideal for large-scale continuous production.

FAQ for R-series Raymond Mill

How to select the R-series Raymond Mill?

Priority should be given to output. Choose 3R for small-scale production, 4R for medium-small scale, 5R for standardized industrial production and 6R for large-scale continuous production.
