May 05, 2008 · The most common cause of dusty clinker is excess sulphate over alkali in clinker. High sulphate cycling in the kiln can be caused by reducing burning conditions. Low back-end O2 would be a symptom of that. The ring in the kiln may be the cause of the low draft, therefore reducing conditions and possible high sulphate content

Dust is the main pollutant from the cement industry. Many links in the cement production process, such as raw material crushing, raw meal grinding, clinker calcination, cement grinding, etc., have different degrees of dust spillover. Among them, the clinker calcination stage has the most serious dust emission degree, accounting for more than 70% of the total dust emission of the cement plant. A large amount of dust
