    Raw Mill In line kiln raw mills are used to route the kiln exhaust gases to the raw mill to dry the raw meal. When the raw mill is on, a large portion of the mercury exhausted from the kiln is fed back into the raw mill. A number of studies show that a majority of mercury in particulate dust is recaptured at the raw mill, resulting in lower.Raw materials must be continually adjusted. With such multi component raw materials, it is impossible to keep all composition factors the same. So the cement characteristics will vary, as will the characteristics of all concrete components.
