A Study on the Failure of Steel Chains in Rotary Cement Kilns

Jan 30 2018 · The failure of steel chains which are used in rotary cement kilns costs cement companies a significant price. This study investigated the causes of chains failure at the Kufa cement plant and proposes new materials that can serve for a prolonged period of time. Two grades of steel chains were investigated including DIN 1.4742 (AISI 10F) and St37.

Temperature Measurements in Cement Latest News Articles

Dec 14 2018 · The Rotary Kiln. The rotary kiln is the key component in a cement plant. It is a long steel cylinder lined with refractory brickwork to protect the outer shell from the high temperatures of the interior. The kiln is very large up to 4 m diameter and up to 50 m long. It typically rotates three to five times per minute.

Temperature Measurement for Cement Lime Kilns

Mid-Kiln. Most modern kilns have a 4 to 5 inch inside diameter by 4 to 5 foot long target tube in the sidewall of the kiln where monitoring mid-kiln temperature is critical to ensure kiln integrity. A PSC Non-Contact Infrared (IR) Pyrometer is recommended for measurement reading during each rotation of the kiln.
