Mill scale, often shortened to just scale, is the flaky surface of hot rolled steel, consisting of the mixed iron oxides iron(II) oxide (FeO), iron(III) oxide (Fe 2 O 3), and iron(II,III) oxide (Fe 3 O 4, magnetite).. Mill scale is formed on the outer surfaces of plates, sheets or profiles when they are being produced by rolling red hot iron or steel billets in rolling mills.
A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.
Observing all of the above losses which are resulted out of boiler scale formation, it is very important to avoid the scale formation. On financial fronts, scales and deposits can aggravate following costs/ losses1. Higher maintenance costs. 2. High repair costs in case of tube failures. 3. Down times which can affect the production line badly. 4.
Production reached a high of Gt in 2014 and has since remained at around Gt. China is the largest cement producer, accounting for about 55% of global production, followed by India at 8%. Without efforts to reduce demand, annual cement production is expected to grow moderately to 2030.
