Calizamar uses BHS-Sonthofen crushing technology to produce sand

The Dominican building materials manufacturer Calizamar is using a BHS-Sonthofen RPM 1513 rotor impact mill to produce high-quality crushed sand. The recent installation of the BHS RPM 1513 unit means there are now three BHS-Sonthofen crushing plants operating in the Caribbean.

The demand for dry and fine sand for dry mortar and concrete production is constantly increasing. That is why companies such as Calizamar need high-quality crushed sand with consistently reliable properties for their products. As its original mobile impact crushers were unable to produce appropriate crushed sand with the desired high cubicity, the search for new, suitable machines led Calizamar to BHS-Sonthofen and the firm’s BHS RPM 1513 solution.

The BHS rotor impact mill of type RPM 1513 in use for sand production: The high-performance crusher achieves a high crushing ratio with a vertical shaft.

The high-performance BHS RPM 1513 plant features a vertical shaft and delivers high crushing ratio as well as an excellent cubic particle shape. It is based on an impeller rotor that uses BHS’s unique crushing principle: the high circumferential speed of the rotor results in an almost permanent gap between the tips of the horseshoe-shaped hammers and the anvil ring. A small gap width and the high energy input due to the circumferential speed produce a targeted, very high crushing ratio. The result, in percentage terms, is a higher proportion of fine sand in the grain spectrum from 0 to 2 mm.
