At a milling speed of 300 rpm, at first glance, the graph shows a uniform grain size reduction in feldspar and quartz. For limestone, greater amounts of ultrafine fractions in the region of to mm were already formed. Furthermore, the content of ultrafine particles below mm was almost twice as high in limestone as in feldspar.
