Since the development of comprehensive utilization vertical roller mill since 1990, has been the use of fly ash grinding equipment of fly ash is 1730000 T, which is dug mountain ash 1280000 t. Kaifeng vertical roller mill ash t for almost 400000 years, until 1990, running two ash field have been filled. Due to actively carry out comprehensive utilization, ash field and prolong the service life of two years.
