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.

Abstract The current world consumption of cement is about 1.5 billion tonnes per annum and it is increasing at about 1% per annum. The electrical energy consumed in cement production is approximately 110 kWh/tonne, and around 40% of this energy is consumed for clinker grinding. There is potential to optimise conventional cement clinker grinding circuits and in the last …

Effect of grinding aids on closed circuit cement grinding As introduced before, grinding aids are sprayed in the mill, or added on the clinker, with dosages usually ranging from 100-200 g up to 2-3 kg per ton of cement. Once a grinding aid is added during cement manufacturing, the main effect is the reduction of separator reject: more
