Roller Mills

Many vertical airswept roller mills (such as those manufactured by Bradley® Raymond® & Williams®) were originally installed with older style whizzer or static cone separators.
These types of separator are particularly inefficient on fine grind applications.

5057 Raymond® roller mill with MCS-250 high efficiency turbine classifier.

The whizzer separator originally supplied in the 1950's with this mill was replaced in 1993.

With an optimized airflow the mill achieved a 40% increase in capacity when grinding kaolin clay to 99.9% minus 325 mesh.

The recent demands of increased production with cleaner topsize cuts in the airfloat kaolin industry are met with the roller mill classifier retrofit from RSG Inc.


6669 Raymond® Mill with MCS-500 high efficiency classifier.


This retrofit on limestone replaced a 9 foot double row Whizzer separator.

The new classifier produces a sharper top size cut on 200 mesh products and upto 50% increase in production on 325 mesh products.
