In a ball mill, size reduction takes place by impact and attrition. In a vertical mill the bed of material is subject to such a high pressure that individual particles within the bed are fractured, even though the particles are very much smaller than the bed thickness. Early issues with vertical mills, such as narrower PSD and modified cement hydration characteristics compared with
