For the dry process. 1400 to 1500'.

For the wet process. 1500 to 1600'.

The temp range in a cement kiln is;

1450° to 2000° c.

It's 1300° to 1500° c.
so, 1400°c is correct.

1400-1600 is burnt temperature but answer is 1400, How? Explain, please.

Actually, the value is in the range of 1300-1500 ° C.

The mixture of different ingredients of cement, known as raw mix, is burnt in a rotary kiln at a temperature of about 1400–1500°C. This high temperature is required to form clinker, which consists of key compounds like tricalcium silicate (C₃S), dicalcium silicate (C₂S), tricalcium aluminate (C₃A), and tetracalcium aluminoferrite (C₄AF).

After burning, the clinker is cooled and then ground with gypsum to produce the final cement product.
