Everything you need to know about Preheaters and Precalciners
ALKALI BYPASS. Alkali compounds enter the production cycle in the rotary kiln system from the raw meal, mostly with the argillaceous component. Since the 1930s, it was known that soluble alkali in the cement matrix react with concrete aggregates contributing to concrete deterioration under the service conditions.

New chloride bypass technology for Boral's Berrima Works
Work on Boral Cement Ltd's upgraded chloride bypass at the company's Berrima Cement Works in Australia has been completed.. The bypass reduces the plant's reliance on coal and enables it to increase its alternative fuel use, lowering its CO 2 emissions. As a result, the plant will be able to achieve a thermal substitution rate of 60 per cent over the next three years.
