The medium-speed mills operate within 50 and 300 r/min, the low-speed mills within 15 and 25 r/min, and the high-speed mills within 750 and 1500 r/min. In recent years, medium-speed mills have been widely used in thermal power plants due to their cheap initial investment costs and low power consumptions.

pressure regardless of the type of medium-speed, vertical spindle pulverizers you use. In our experience the spring frame of an MPS mill tuned for maximum true capacity will be set at about 20 tons minimum force on the grinding tires. A bowl mill spring or hydraulic preload for this size of mill will also be about 20 tons of pressure.

13.1.1.2 Medium-speed mill. Medium-speed mills are smaller than low-speed units and are generally of the vertical spindle construction. The speed of the grinding section of these mills is usually 75–225 rpm. They operate on the principles of crushing and attrition. Pulverization takes place between two surfaces, one rolling on top of the other.

Coloured malts and speciality malts generally gum up the filter bed and have a negative effect on wort separation. Milling more coarsely reduces the particle size and improves the filter bed porosity helping to speed up filtration. If you mill to the same settings as your base malt and don't have any issues, don't worry about it.
