Sand

High-quality crushed sand

Crushed sand can be produced with our rotor impact mill (type RPM) or rotor centrifugal crusher (type RSMX). Both machines operate based on an impact principle and feature a vertical-shaft rotor. In both cases, this ensures high yields of sand, excellent cubical shapes and the ability to optimize the grain-size curve of the final product. In addition, both machines guarantee a consistent grain-size curve of the output material over the entire lifespan of the crushing tools.

The rotor impact mill is especially suitable for less abrasive rock types (e.g., limestone) with feed sizes up to 56 mm. An extremely high crushing ratio is achieved without producing excessive filler content.

The rotor centrifugal crusher is suitable for all types of rock, without restrictions. The maximum feed size is 150 mm. Rotor centrifugal crushers also offer significantly higher throughput rates than rotor impact mills. However, the crushing ratio is usually lower.

More efficient crushed sand production

BHS-Sonthofen introduced their new rotor impact mill of type RPMF at bauma 2016. The new RPMF machines produce even finer fractions as well as output material with a significantly higher proportion of fine sand. As such, machines of this type are more efficient in producing crushed sand.

Brought into line - Rotor crushers for the production of sand and fine sand

For the production of sands for the construction materials industry BHS Sonthofen has developed special rotor crushers, which depending on crushing requirements and the application range of the sand product can process soft, medium-hard to hard and wear-intensive rock. At the company's test centre original machines are available for conducting test series. The following paper describes the principle of operation of BHS rotor crushers and presents different examples of crusher performance with reference to screening curves.

Manufacturing of dry mortar sands

The preferred machines for the manufacturing of dry mortar sands are impact mills with a horizontal shaft, hammer mills and rotor impact mills with a vertical shaft. Impact mills can comminute feed material sized up to 120 mm and are therefore suitable for use as a primary crusher. However, they cannot process oversize particles up to 4 mm. Hammer mills with a bar grid produce a significantly higher portion of undersize material up to 0.1 mm (socalled ⌠filler) and should therefore only be used in applications where this is explicitly desired. Rotor impact mills can be used both as primary crushers for feed materials sized up to 56 mm and as secondary crushers for off-spec particle sizes up to4 mm.
