Most California cement plants have a "reverse peak" electric load profile (i.e. their demand is lower during the peak hours) because they consciously defer peak load. They try to stockpile certain crushed products when they can so that they can shut down or slow down large process mills or fans during the on .
Hammer Mill Operating Principle. We have never subscribed to the idea that the hammermill is suited to the primary breaking of shovel-loaded, quarry-run, or ROM mine-run rock and ore. Even though the material be non-abrasive and quite friable there are other machines which are better fitted for such work.
As the cost of refractories is a major expense in operating a cement plant, kiln stoppages are avoided as far as possible. As the meal passes through the burning zone, it reaches clinkering temperatures of about 1400 C - 1500 C. Nodules form as the burning zone is approached.
Plants that burn waste fuels enjoy a negative fuel cost (they are paid by industries needing to dispose of materials that have energy content and can be safely disposed of in the cement kiln thanks to its high temperatures and longer retention times). As a result, the inefficiency of the wet process is an advantage—to the manufacturer.
