Net zero concrete

Jan 18, 2021Beginning in the 1980s, cement manufacturers started installing high efficiency separators in their mill circuits. The separator subjects the cement particles to a cyclonic air current, flinging them to the walls. The large, heavy particles slide down the walls and out the bottom, while the smaller, lighter particles remain suspended.
