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.


The substantial amount of concrete typically used in foundations for large wind turbines requires a concomitant large amount of cement, in addition to sand and aggregate. Production of cement is energy intensive and involves considerable generation of C02. In fact, cement production accounts for approximately 8% of C02


A typical layout of a mill using the kraft chemical pulping process is shown in figure 2-1. Mechanical, semichemical, and sulfite pulp mills differ in detail, particularly in wood preparation, fiber separation, and bleaching, but many of the downstream refining, bleaching, and papermaking processes are similar.
