Early systems used rotary coolers, which were rotating cylinders similar to the kiln, into which the hot clinker dropped. The combustion air was drawn up through the cooler as the clinker moved down, cascading through the air stream. In the 1920s, satellite coolers became common and remained in use .
Grate coolers for use with cement kilns. The cooler at Rodmell replaced the original Edgar Allen reflex planetary cooler, and was in turn replaced in 1957 with a Fuller 633S reciprocating grate.. The buckets and paddles were very susceptible to wear, and the dead material lying on .
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.
The AirQuenching 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.
