Cement kiln - Wikipedia

A typical process of manufacture consists of three stages: grinding a mixture of limestone and clay or shale to make a fine "rawmix" (see Rawmill);; heating the rawmix to sintering temperature (up to 1450 °C) in a cement kiln;; grinding the resulting clinker to make cement (see Cement mill).; In the second stage, the rawmix is fed into the kiln and gradually heated by contact with the hot ...

Temperature control during clinker cooling process | …

A very important process during cement production is the cooling of the clinker, since to a large extent the quality and characteristics of the cement depend on this phase. The hot clinker produced in the rotary kiln is transferred to a cooler, where it is cooled by air blowers before being conveyed to the cement mill.

PERFORMANCE EVALUATION OF A GRATE COOLER IN A …

The performance evaluation parameters considered were clinker temperature, cooler loss and efficiency. The exit clinker temperature was measured to be 56.620C. It is found that 23.90% of the total heat energy (383.51 Kcal/kg.cl) generated is being lost even though a big percentage of this heat (76.10%) was being recovered.

Introduction to Air Pollution - Pollution Control

Control of SOx. The control of SO 2 is largely based on chemical means. The sulfur present in organic compounds can be converted to various forms by oxidation or reduction. Sulfur oxidizes to Sulfur Dioxide (SO 2) and then Sulfur Trioxide (SO 3).In the atmosphere SO 3 reacts with water to form sulfuric acid, which then reacts with ammonia or other -ions to form particles of ammonia sulfate ...
