Ground limestone
Ground limestone VMV 15
VMV 15 ground limestone is produced by grinding natural limestone to the required fineness.
Area Of Use
Due to its high chemical purity and very fine granulometry, it is suitable for the treatment of heavily polluted waste water from industrial processes, the production of asphalt mixes, the construction, glass and chemical industries. It is also suitable for use in the agricultural sector or as an effective sorbent for the removal of sulphur oxide from flue gases in wet scrubbing processes.
