The Use of Refractories in the Lining of Rotary Cement …
Reducing production costs is the main challenge in the cement industry throughout the world, and the performance of the refractories in rotary kilns plays a large role in the effort to solve this problem. The kiln lining has several functions [1–5]. Its main job is to serve as a transport surface along which the semifinished product can travel.
Kiln Control and Operation
1.1 Oxygen control. The oxygen at the calciner outlet is controlled through the calciner draft, in the same way as the oxygen at kiln inlet is controlled by the kiln draft. A normal target value for the oxygen after calciner (bottom cyclone exit) is 1 – 1.5 %.
Heat Balance Analysis in Cement Rotary Kiln
Cement production has been one of the most energy intensive industries in the world. In order to produce clinker, rotary kilns are widely used in cement plants. This paper deals with the energy audit analysis of a dry type rotary kiln system working in a cement plant in Turkey. The kiln has a capacity of 600 ton-clinker per day.

Behaviour of Volatile Materials in Cement Kiln Systems
Abstract. Factors governing behaviour of minor amounts of Cl, K, Na and S in cement production kilns are reviewed. Recirculating loads form as a result of partial volatilisation in the burning zone and are often implicated in formation of build-ups, coating and blockages in cooler parts of the process. Differences arise between plants from ...

Although the rotary cement kiln is a key piece of equipment, attempts for developing computational models to simulate cement kilns were few. Recently, some researchers have been done to develop computational fluid dynamics (CFD) based models to simulate rotary cement kiln (Mastorakos et al., 1999; Lu et al., 2004).

BENEFICIAL USES OF CEMENT KILN DUST
the kiln or otherwise beneficially used is placed in landfills (Bhatty, 2004). Cement Kiln Dust Characteristics CKD consists primarily of calcium carbonate and silicon dioxide which is similar to the cement kiln raw feed, but the amount of alkalies, chloride and sulfate is usually considerably higher in the dust. CKD from
Mechanical Behavior and Microstructure Evaluation of …
Cement kiln dust (CKD) is a by-product of cement production, which has the shortcomings of low utilization and high-temperature activation. This study combined CKD and slag as precursors for preparing pastes through quicklime activation under ambient conditions. The effects of quicklime and CKD content on the workability (flowability and …
