Save Sand by MS

So far, quarry waste rock, as well as construction and demolition waste are mostly considered as Waste. However, spoils have a major asset: the sand. This natural resource, contained in concrete, is becoming increasingly depleted and scarce. But we still need it for new construction ! Waste you generate can become a valuable asset! There are indeed solutions for recycling. Make the most of your recycling and create a new source of income. Make your waste management more responsible, sustainable and cost-effective.

To be involved in your entire process, Build Better by MS offers the new range of SAVE SAND equipment.

Installation adjusted and designed according to your specific needs

The SAVE SAND range covers all the equipment operating for the treatment of your outgoing spoils in a qualitative process while preserving the water used for such treatment. You can also make the transport of sludge more economic by dewatering it.

This mineral processing allows the production of clean, consistent quality 0/4mm concrete sand thanks to attrition, separation, double cycloning, rebounding and sand washing.

Thus, the SAVE SAND range (100 t/h, 150 t/h and 200 t/h) is the only one that allows to :

  • Target a grain size range that can be adjusted according to your needs (fineness modulus according to your request & special sands)
  • To achieve an optimal sand cleaning in terms of blue value (≤ 1.0)

Your spoils, coming from various sources, may contain more or less sand, scrap metal, clay, plastic, concrete, fines, cardboard, polystyrene etc…

Despite the variation, you will produce consistent grain size and quality material. In order to meet your expectations, OPTIONAL steps are also available:

  • Pre-screening: control and regulation of inputs granulometry
  • Overband : separation of metallic elements
  • Logwasher : removal of clays / light contamination.
  • Attrition: advanced screening process for fine grain sizes

A single, global offer covering the entire valorisation process of your products to be recycled!

Choose sustainable equipment to :
- transform your outgoing waste into added value
- preserve the environment by meeting today's challenges.


In the Save Sand installation, contaminated waters coming from the materials washing, are clarified so that all the equipment in the process (screens, washers, dewaterers) can be supplied with quality and recycled water.
