To produce cement, the raw meal is burned to clinker in a long rotary kiln. After leaving the rotary kiln, the clinker has a temperature of up to +1300 °C and must be cooled down to a temperature of about +200 °C for further storage. To achieve this, the clinker bed is cooled with a continuous stream of air. Pressure

CLINKER FORMATION AND CLINKER GRANULOMETRY It is a well-known fact that the granularity of clinker products can vary considerably from one cement plant to another. Even kilns within the same plant are often found to produce quite different clinker, although fed with the same raw mix.

Portland cement clinker is a nodular material made by heating ground limestone and clay at temperatures of 1400 to 1500 C. The resulting cement contains several miner-als, including tri- and di-calcium silicate, tricalcium alu-minate and tetracalcium aluminoferrite.1 These phases contribute to the high abrasion properties of the clinker

Characterization of clinker and cement Free lime contents "Free lime contents" in clinker and cement (Fig. 5) are an essential parameter to judge the improvement in calcination. It is worth noticing that the sintering process of the clinker is followed by the decrease in free lime contents when temperature increases.

14 Cement Mill and Bag House . Clinker, along with additives, is ground in a cement mill. The output of a cement mill is the final product viz. Cement. In a cement mill, there is a cylindrical shell lying horizontal which contains metallic balls and as it rotates, the crushing action of the balls helps in grinding the clinker to a fine powder.

In cement plants, where hammermills or impactors are used for secondary crushing of cement rock, the feed is approximately 6-10" (150 - 250mm) and the product is a nominal 1/2 " (12mm). This reduction needs 11/3 to 11/2 HP per net TPH. Impactors generally require approximately 1 HP per TPH (gross load) to drive them.

With a gyratory crusher, at any cross section there are in effect two sets of jaws opening and shutting like jaw crushers. In fact, the gyratory crusher can be regarded as an infinitely large number of jaw crushers each of infinitely small width, and, as consequence, the same terms gape, set, and throw, have identical meaning in the case of the gyratory crusher.
