Clinker Cooling Technology Mechanical

Clinker cooling is necessary because. 1. Hot clinker is difficult to convey. 2. Hot clinker has a negative effect on the grinding process. 3. Reclaimed heat content of the hot clinker is an important factor in lowering the production cost. 4. Proper cooling improves the quality of cement.

Jan 10, 2012 re Clinker cooling rate vs Cement Performance. Ted has given the actual details, Effect of different things on slow and fast cooling is given below, slow cooling means 4 to 5 degree per minute and fast cooling is 18 to 20 degree per minute. MgO Slow cooling Forms pericles crystals ,Fast cooling Light brownish yellow clinker.

The central location of the air stream avoids premature chilling and slow cooling of the clinker, which discharges in a partly molten state and falls through a chute, designed to prevent air counter70 flow, the clinker passing directly to a primary cooling chamber wherein it forms an inclined bed resting upon the cooling elements.

Reactions In The Cement Kiln Clinkering

Fast cooling of clinker is advantageous - it makes for more hydraulically-reactive silicates and lots of small, intergrown, aluminate and ferrite crystals. Slow cooling gives less hydraulically-reactive silicates and produces coarse crystals of aluminate and ferrite. Over-large aluminate crystals can lead to erratic cement setting characteristics.

C. David Lawrence, in Leas Chemistry of Cement and Concrete Fourth Edition, 1998. Effect of proportions and activities of the main clinker minerals on water demand and fluidity. Slow cooling during clinker production results in an increased reactivity, due to the production of larger crystal sizes for C 3 A, and consequently larger water demand. 77. Effect of sulfate type and content on ...

It has been observed that a moderate rate of cooling of clinker in the rotary cooler gives about 3.7 higher strength of cement at 28 days than quick cooling and about 11.1 less strength at slow cooling. The results based on the experiments carried out by ENKEGAARD are shown in Table 2.1.

that this clinker was processed under slow cooling. 75. ACXRI 96 CONCLUSION There is a difference between the inner and the outer parts of the clinker nodules. The outer part contains larger alite crystal size and the belite crystals are distributed without any clusters comparing with the inner part. Also there is a difference in the
