Large amounts of electricity are used grinding the raw materials and finished cement. Today, the main direction in the cement industry for saving both resources and energy is the development of low-clinker or blended cements using one-component and complex mineral additives. In order to reduce CO2 emissions from the cement industry an effective an economically feasible technology is to be developed. Limestone is a softer material than clinker and therefore takes less energy to grind to the same fineness. Calix magnesium-oxide reactor at Bacchus Marsh near Melbourne, Australia, which has been operating since October 2013. INTRODUCTION Today, cement clinker is produced by combustion of fuels. Cement kilns are mainly used for calcination of cement clinker, divided into two categories: dry production cement kilns and wet production cement kilns. The production of cement clinker and burnt lime involves calcination, or the decomposition of calcium carbonate in limestone by heating. After calcination, the cement clinker will enter the cooler for cooling. Liebherr concrete technology The calcination process takes place in a rotary kiln, or â in modern kiln lines â in the calciner, which forms part of the high preheating tower. The production of cement clinker from limestone and chalk by heating limestone to temperatures above 950°C is the main energy consuming process.
