A new milestone for clinker cooling technology

World Cement,

ETA Cooler®, the concept for cooling clinker in the cement making process announced by Claudius Peters Projects GmbH in 2004, has reached a new capacity milestone with a more than 13 000 tpd model going into production earlier this year in China.

Since introducing the ETA Cooler® principle to the cement world in 2004 with the first 2000 tpd installation at a Holcim Cement plant in Switzerland, the technology has been widely acclaimed over traditional and competing technologies for its efficiency and versatility.

Over the last decade or so the company has progressively offered the market increasingly higher capacity models, now reaching 13 000 tpd – currently the world's highest capacity cement line production. Even higher capacity is feasible.

Due to its unique design, no dust removal system is required with ETA Cooler® and the relatively long stroke action means a low grate speed, which in turn means less wear and maintenance. And, as there is no obstructions to the clinker flow in this moving floor technology, a high transport efficiency is also achieved, with uniform cooling, thus improving the quality of the clinker and in turn the quality of cement produced.

This all adds up to lower operating costs with increased reliability and product quality. Moreover, ETA Cooler® has a very low construction profile, virtually guaranteeing it can be installed as a retrofit option to any existing cement producing line. Its modular design also means that ETA Cooler® can be installed with minimal production downtime.
