Figure 1: EBITDA profit margin
Financial ratio analysis is used to assess the condition and performance of cement companies based on the performance published in their financial statements, such as their income statement (profit and loss), statement of financial position (balance sheet) and statement of cash flows. Two figures from the financial statements are divided by another to produce a ratio of one to the other. As it is a ratio, the gross profit margin can be compared from period to period, between business units or even between companies. The actual magnitude of the revenue or profit is normalised by the ratio, making such comparisons more meaningful.

Dealing with dust
Published 16 February 2021
With dust chemistry varying between direct operation when the raw mill is out of action and indirect operation when the raw mill is running, finding a destination for baghouse dust while maintaining a homogenous kiln feed is a long-standing issue in cement production. By John Kline and Benjamin Kline, Kline Consulting LLC, USA.
Figure 1: a typical raw mill and kiln feed configuration
The simple question of what to do with baghouse dust when the raw mill is out of operation has plagued the cement industry since the invention of the rotary kiln. In wet kilns the dry dust was difficult to mix back in as it impacted the slurry characteristics. New inventions such as dust insufflation and mid-kiln dust scoops were developed to manage the problem. In long dry kilns dust was less of an issue. However, with the advent of the preheater the dust problem returned. The issue being that the dust chemistry varies between direct operation with the ra
