The processed grains are cubical, but their edges are rounded, and the company says that dry mortar produced with this type of sand is easier to use and makes concrete easier to pump.
Last year BHS-Sonthofen delivered many RPM-type rotor impact mills for new dry mortar factories in fast-growing Asia and the Middle East.
BHS says the rotor impact mills are increasingly being used for other applications, being employed more frequently to make sand for ready-mixed concrete; in the asphalt industry; in the manufacture of surfaces for sports facilities, as well as for grinding limestone, dolomite, gypsum, anhydrite and quicklime.
The mill can process feed sizes up to 56mm. Larger feed sizes can be used for materials that are easy to crush, such as quicklime. Throughput can reach 75tonnes/hour.
