Cement grinding Vertical roller mills versus ball mills. The grinding process in ball mills and vertical roller mills differ fundamentally. In a ball mill the comminution takes place by impact and attrition. The comminution in the vertical roller mill takes place by exposing a bed of material to a pressure sufficiently high to cause fracture of the individual particles in the bed, although the

Keywords: Vertical roller mill, cement grinding, performance evaluation INTRODUCTION Cement production is highly energy consuming process with energy utilization of around 110150 kWh/t (Villa, 2005). Majority of this energy (40 %) are consumed for finish grinding. High energy consumption, increasing demand and the emission of CO 2 necessitate the efficient grinding technologies. Among
WhatsAppعرض المزيدThe effect of grinding aids on the comminution of cement is based on the dispersion of fine particles. It is a misunderstanding that grinding aids for vertical roller mills (VRMs) should stabilise the material bed between the rollers and the table by adhesive forces between the particles. Grinding aids reduce the polarity of the cleaved surface and the attraction forces between particles. This
