In these coolers, the clinker is cooled from about 1100°C to 93°C (2000°F to 200°F) by ambient air that passes through the clinker and into the rotary kiln for use as combustion air. F. Finish Grinding: The clinker tumbles onto a grate cooled by forced air. Once cooled, the clinker is ready to be ground

clinker. After cooling, the clinker can be stored in the clinker dome, silos, bins, or outside in storage piles. The material handling equipment used to transport clinker from the clinker coolers to storage and then to the finish mill is similar to that used to transport raw materials (e.g. belt
cement clinker. The modification includes raw material handling and storage, kiln feed preparation with an in-line raw mill, a dry process rotary kiln coupled with preheater and calciner, a clinker cooler, a coal/pet coke mill, a finish mill, and cement storage, packaging and shipping operations.
manufacturing operations, such as blending silos, kilns, clinker cooler, and clinker grinding/milling, are surrendered or have expired and are no longer reinstateable. (18) FINISH MILL means a roll crusher, ball and tube mill or other size reduction equipment used to grind clinker to a .

The cost savings from replacing clinker with additives (see Item 1 above) are likely to be the largest. While production costs are plant-specific, a plant producing one million tons of cement per year will produce less clinker equivalent to the amount of finish mill additives added, i.e. 5% clinker saving in this case or 50,000 tons per year.

The Air-Quenching shaking grate Clinker Cooler was developed more than 20 years ago as an improved heat recuperating cooler for use with rotary kilns. It was designed to air quench and cool large quantities of hot clinker rapidly, and to recover and return to the kiln a major portion of the heat from the clinker.
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.Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.
Sep 19, 2019 · The kiln heats the clinker, the name for the dried material formed after the grinding process, until it reaches upwards of 2732°F (about 1500°C). Afterward, the material is sent to a clinker cooler where the temperature lowers to a reasonable level, .
