Sustainable production of crushed sands

Crushing technology for producing high-grade crushed sands

Our machines are ideally suited to producing crushed sands. Not all sand is the same, and the shape and composition of many naturally occurring sands is unsuitable for the construction materials industry. Discover an economical process for producing sand with consistent properties. Our process stands out thanks to its high quality and the responsible use of resources it unlocks.

Benefits at a glance:

Proven und forward-looking VSI impact crushing technology
High and efficient sand yield
Cubic particle shape and consistent sand grading curve
Low maintenance requirements
Large number of references across the globe

Impact crushing technology for producing crushed sands

Our rotor impact mill (type RPM) and rotor centrifugal crusher (type RSMX) crushing systems ensure best results in the production of crushed sand. Both machines operate based on the impact principle and have a rotor with a vertical shaft. This enables you to achieve high sand yields and the desired cubic particle shape. The adjustable speed furthermore allows you to configure the grading curve of the end product according to your requirements. With both machines you can rely on a constant grading curve of the output material over the entire service life of the crushing tools.

Success stories

Premium sand from off-spec particles

July 2019

Sand manufacturer Kasprs Build Mate inaugurated a new plant for processing off-spec particles in Pune, India. The centerpiece of the plant is the rotor impact mill from BHS-Sonthofen, which, in contrast to conventional VSI rotor crushers, even further reduces fine grain sizes. Kasprs can thus make use of off-spec material of other companies to produce high-quality Plaster Sand and Dry Mortar Sand for the construction industry.

Cubification of sand in the United Arab Emirates

September 2018

The large quantities of natural sand in the region do not have the properties required for the construction projects in Dubai and Abu Dhabi. Therefore, mine operator Stevin Rock manufactures the sought-after commodity out of limestone in the United Arab Emirates. Two rotor centrifugal crushers of type RSMX have been used for the final – and crucial – finishing step since September 2018. The two RSMX crushers with TwinDrive break the particles down into the ideal shape, ensuring a consistently high sand quality.

Plant design for production of sand for dry mortar

February 2014

Dry mortars have become highly efficient building materials to which high production standards are applied. In particular, the excellent cubicity of the sand particles plays a key role in making the mortar easy to use and easy to pump. Carefully designed crushing equipment can efficiently and economically produce dry mortar sands that correspond exactly to the formula.
