The Atlas is a roller air-swept mill designed for continuous operation with minimum maintenance. The fundamental difference between the Atlas and other table-roller mills is the bearing arrangement for the grinding table which is incorporated into the base of the
Chat OnlineThanks to its grinding plants with throughputs of 2 to 1000 t/h for the cement industry and self-inert central coal-grinding plants for hard and brown coal power stations Loesche is the global market leader for vertical roller mills and turnkey grinding mills.
Chat OnlineMilling is the process of machining using rotary cutters to remove material by advancing a cutter into a work piece. This may be done varying direction on one or several axes cutter head speed and pressure. Milling covers a wide variety of different operations and machines on scales from small individual parts to large heavy-duty gang milling operations.
Chat OnlineThe 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

Chat OnlineThis case study considers a retrofit of a duct system at a cement plant. The objective of the retrofit is to blend ambient air with hot gases going to a vertical roller mill for temperature control. The objective of the CFD analysis was to minimise the temperature difference between the two streams of gases entering the vertical roller mill.
