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

Hydraulic Roller Press Flexible capacity. Low energy

high pressure over a short time. The pressure forms micro-cracks in the feed particles, leading to the generation of a large amount of fine material. For upgrade projects, using an HRP together with a ball mill significantly reduces overall specific power consumption and increases system production. In ball mills, less power is required

Improving Mill Shoe Bearing Reliability and Productivity

Feb 22, 2019 This is provided by a high pressure oil pump which delivers oil between the bearing and journal. The oil, injected under pressure, lifts the mill and helps to reduce the friction between the shoe and ring, providing alignment. The minimum oil viscosity for most mills is 44 cSt at 100°C and typically requires an oil with an ISO 460 Cst viscosity.
