Cement kiln coprocessing takes raw materials such as calcium carbonate and silica, and feeds them into a kiln along with fuel. The process, which is used to create cement, includes burning the materials to such a high temperature that any complex part is broken into simpler compounds. The end result of the process is cement.
Lime rotary kiln has many advantages in the process of processing lime ore, it is also known as lime kiln, is a professional calcination equipment, its main advantages are large production capacity, no noise, low comprehensive energy consumption and so on.

A case study of hightemperature corrosion in rotary cement kilns by Potgieter*, Godoi†, and R. van Grieken† Synopsis This paper describes two cases of corrosion that occurred in dryprocess, rotary, cementclinker kilns. In the case of the kiln with five preheater stages, the attack occurred primarily from sulphates
Paint sludge waste coprocessing at the ACC Wadi Cement Works in Karnataka, India S. P. Gautam1, P. S. Bundela2 M. Murumkar3 1Central Pollution Control Board, New Delhi 2Madhya Pradesh Pollution Control Board, India 3AFR Regional Supply Chain North Region, ACC Ltd, India Abstract Coprocessing in a cement kiln is an effective, environmentally friendly and safe
Mechanism of Waste Management Through Coprocessing In Cement Kiln The organic constituents are completely destroyed due to high temperatures, long residence time and oxidizing conditions in the cement kiln. Acid gases such as HCL and SO 2 are absorbed and neutralized by the freshly formed lime and other alkaline materials within the kiln.
Abstract: Problem statement: Coprocessing in cement kiln perforce provides high temperature and long residence condition during the operation and is an effective technology for the management of waste in an environmentally friendly and safe manner. It fully absorbs the energy and material value of the waste without any harmful emissions.
The objective of the paper is to present a review of the coprocessing of industrial waste in cement kiln and its sustainability based on three case study approach. The study will show the economical and environmental gain achievable by using industrial waste as AFR in Indian cement kilns.
