— The clinker cooler is an essential element in the production of cement The cooler as the name implies cools the clinker to manageable levels while transporting it away from the kiln It also recovers heat from the clinker for use in the kiln precalciner and other areas In addition the cooler sizes the clinker breaking up large pieces

A clinker cooler is a major element of manufacturing clinker Ground raw meal made from limestone is turned into clinker within a rotary kiln The raw materials clay limestone and some minor additives are ground and blended in a raw mill At this point the mixture is called raw meal
— of the clinker bed and thus the clinker bed depth and clinker throughput are optimally controlled over the entire width of the cooler Implemented for the first time in a clinker cooler this solution provides the best pre conditions for consistent and uniform cooling of all grain size fractions Intermediate crusher concept

Clinker cooler upgrades typically increase throughput and energy efficiency In turn the latter reduces emissions Mokra Plant in Brno Czech Republic The Mokra cement plant opened in 1969 The plant s existing grate cooler was inefficient due in part to a clinker bed height of only two feet Higher demand for cooling air reduced thermal
— Much like the rotary kilns that feed them clinker coolers in cement making are also subject to extremely high operating temperatures and dust levels Bearings on the cooler grates also have to operate at low speeds under moderate to high loads Facing these challenges SKF solutions can help to ensure your clinker cooler and its

Coolers are used with rotary kilns to rapidly cool hot clinker or other materials exiting the kiln The latest generation clinker cooler of Sinoma tec has the characteristics of Three high and one low high cooling efficiency High transmission efficiency and high operation rate super low wear
WhatsApp
To achieve this the clinker bed is cooled with a continuous stream of air Pressure monitoring is required in the lower part of the clinker cooler to make the cooling as effective as possible The material height of the hot clinker at over 1000 °C on the conveyor belt also has to be reliably measured
