The generation of Power from the cement kiln Waste Heat gases is an energy saving opportunity and it entails the recovery of the heat energy contained in the waste gases that are emitted into the atmosphere from the cement kiln.
Quite a few wet process kilns are still in operation, usually now with highertech bits bolted on. However, new cement kilns are of the ''dry process'' type. Dry process kilns. In a modern works, the blended raw material enters the kiln via the preheater tower.
Like in any cement plant, the Bag House operates in two basic modes of operation: 1. Direct Mode Of Operation All the Preheater exit gases shall be routed directly to bag house since the raw mill is not operating. 2. Compound Mode Of Operation Here the Raw Mill is in running condition, therefore major part of Preheater exit gases will
Temperature is a crucial process parameter in the manufacturing of cement. The correct monitoring of temperature at various stages of the process Kiln Motorbearing, Conditioning tower, Flue discharge, Preheater cyclones, Smokebox and fuel storage determine the quality of clinker and the final product.

conditioning. The principal configuration of an oxyfuel cement plant remains almost unchanged compared to conventional technology and is illustrated in Figure 11. In terms of retrofitting an existing kiln plant, the initial geometry of the rotary kiln, preheater tower and calciner is kept unaltered.
Plants that burn waste fuels enjoy a negative fuel cost (they are paid by industries needing to dispose of materials that have energy content and can be safely disposed of in the cement kiln thanks to its high temperatures and longer retention times). As a result, the inefficiency of the wet process is an advantage—to the manufacturer.
This can choke the preheater with a large buildup to the point that airflow can no longer be maintained in the kiln. It then becomes necessary to manually break the buildup away. Conventional Solutions Reliable methods of monitoring flow through the preheater tower cyclone represents best practice.
Here the Raw Meal gets preheated. It consists of 6 stages of cyclones. It is finally directed to the kiln via the dividing gate. There is also a swan neck arrangement for the gases such that the calciner can direct the hot gases to the 2 Nos. Perheater strings.
Kiln preheater towers provide heat transfer from hot gases to kiln feed material. The counterflow of gases and material takes place in cyclones, referred to as stages, in the preheat tower. As material flows from the top to bottom of the tower, it is exposed to increasingly higher temperatures as it .

Such heat as escapes the preheater is used to heat the rawmill. The concept of the suspension preheater gradually emerged when, from the 1920s onward, some kilns started to be fitted with cyclones to remove most of the dust from kiln exhausts, and to return it to the kiln.
Ball Mill. Ball mill is the key equipment for grinding after the crushing process, which is widely used in the manufacture industries, such as cement, silicate, new building material, refractory material, fertilizer, ferrous metal, nonferrous metal and glass ceramics and can be used for the dry and wet grinding for all kinds of ores and other grindable materials.
