Cement rotary kiln, which is mainly used for calcinating cement clinker, is the main equipment of the new dry type cement production line. This equipment is mainly composed of cylinder, supporting device, supporting device with catch wheel, transmission device, lubrication device, mobile kiln head and sealing device at the end of the kiln. 1.
5.5.2 Combustion of Hazardous Wastes in Rotary Kilns. Cement kilns are the most common users of hazardous wastes as blending fuels. Cement kiln energy recovery is an ideal process for managing certain organic hazardous wastes. The burning of wastes or hazardous wastes as supplemental fuel in the cement and other industries is not new.
Cement kiln refractories. Refractories play a critical, if unseen, role in both the rotary kiln lining, and the lining of the high volume static equipment areas that comprise a modern pre-calciner kiln system. The durability of the rotary kiln brick lining generally determines the duration of a kiln …
A cement plant uses a rotary kiln, also referred to as a cement kiln or rotary cement kiln, to heat raw material into a product commonly referred to as 'clinker.' While the types of cement kilns have changed and evolved over the years, modern cement processing typically uses a continuous direct fired kiln to thermally process material.

CEMENT ROTARY KILN Questions & Answers Question-1: What is the maximum continuous shell temperature a kiln stands without permanent damage to the shell? Answer-1: The maximum recommended kiln shell temperature varies by plant, by country and by kiln manufacturer, despite the fact that most kiln shells are made of low alloy carbon steel.
PAHs (according to EPA 610) in the exhaust gas of rotary kilns usually appear at a distribution dominated by naphthalene, which accounts for a share of more than 90% by mass. The rotary kiln systems of the cement industry destroy virtually completely the PAHs input via fuels. Emissions are generated from organic constituents in the raw material.
