Mill finish aluminum refers to the original, unpolished state of the metal that has not been treated or finished in any way. This form of the metal is largely untouched, with the surface often appearing somewhat dull. Mill finish aluminum has not undergone any further processing after being produced from raw aluminum through an extrusion process.

Clinker grinding technology is the most energy-intensive process in cement manufacturing. Traditionally, it was treated as "low on technology" and "high on energy" as grinding circuits use more than 60 per cent of total energy consumed and account for most of the manufacturing cost. Since the increasing energy cost started burning the benefits …

Definition of Clinker. Clinker is a hard, black, or dark grey substance created when coal is burned. It's made of ash, soot, and minerals that fuse together at high temperatures. Clinkers can form on the fire grate, inside combustion chambers, or in flue pipes. These lumps can damage furnace components and reduce efficiency if not removed.

When clinker cooler air is used for coal mill heating, the fine carry-over dust can add large amounts of inert 'ash' to the ground coal. This can interfere with combustion and limit kiln output. The abrasive dust also accelerates equipment wear and makes burner pipe and snowmen buildups more likely. Dusty clinker can also have poor ...
