    Ball Mills an overview ScienceDirect Topics

    Diagram of cement ball mill. (Based on an image from ThyssenKrupp AG. 15) Much of the energy consumed by a ball mill generates heat. Water is injected into the second chamber of the mill to provide evaporative cooling. Air flow through the mill is one medium for cement transport but also removes water vapour and makes some contribution to cooling. Grinding is an energy intensive process and

    VRM has been a more compact unit is quite smaller about the ball mills thus significantly reducing civil engineering cost about a ball mill plant. Ball mills are factory made and transported to the plant site of the buyer while VRM is built on the site of the cement plant. This helps to reduce cost and complicated logistics issues. The equipment cost is, however, higher for a VRM than a ball mill.

    Rawmill Wikipedia

    Occasionally, the mill is preceded by a hot-air-swept hammer mill which does most of the drying and produces millimetre-sized feed for the mill. Ball mills are rather inefficient, and typically require 10–20 kW·h of electric power to make a tonne of rawmix. The Aerofall mill is sometimes used for pre-grinding large wet feeds. It is a short, large-diameter semi-autogenous mill, typically
