Cement production: using bypass dust to reduce energy costs

CEMENT INTERNATIONAL

A new method makes it possible to use up to 100 % alternative fuels for clinker production and to recover the resulting bypass dust as a recyclable material. Indexing belt filters from BHS-Sonthofen enable the bypass dust obtained during the production of clinker to be completely reintroduced into the process when using up to 100 % of the more costeffective alternative fuels in cement kilns. Reintroduction of the recovered bypass dust increases cement production by up to 3 %. Proof that the method works reliably on a commercial scale has been provided by a new plant with an annual capacity of 20000 t.
