Burning clinker for high-alumina cement in a rotary kiln ...

We prepared clinker for high-alumina cement in a rotary kiln and determined the material balance in firing when preparing the raw mixtures with two methods: granulation in a plate granulator and briquetting on a roller press. It is shown that much less dust removal (4%) is ensured by firing the briquets obtained on the roller press. The aluminous cement obtained with this technology has …
