The Challenge: Fine Sand with Impurities
In many regions, high-grade natural sand is becoming harder – and sometimes more expensive – to source. At the same time, existing deposits often include fine sand with a mix of unwanted components. Traditionally, this fraction is written off as waste.
Producers then have to buy large amounts of additional sand. That adds cost, increases transport needs, and puts more pressure on natural resources. It’s a familiar problem in the concrete industry, and one many producers would really prefer to avoid.
The Process: From Unusable to Valuable
The plant shown in our video demonstrates a practical way to recover useful coarse particles from fine sand that would otherwise be discarded. The concept is straightforward, yet surprisingly effective.
The workflow includes:
- Removing impurities step by step
- Processing fine sand so coarse, concrete-relevant particles can be extracted
- Coordinating equipment that is built to work together
The Technology Behind It
- SIEBTECHNIK TEMA provides the screening machines for efficient separation and constantly high throughput.
- STEINHAUS supplies the screening media that ensure durability and sharp cutpoints.
- Multotec contributes pumps and cyclones that keep the classification process on track.
Because all three companies are part of the same group, the system components align naturally. Interfaces shrink. Implementation becomes easier. And operators get a process that feels coherent rather than cobbled together.
The Result: Less Purchased Sand, More Resource Efficiency
By processing the fine sand, the plant needs to purchase only about two thirds of the previously required volume. The remaining third comes from material that was once considered unusable.
This shift comes with clear benefits:
- Lower procurement costs
- Less transportation effort—and fewer related emissions
- Consistent, constant material quality for concrete production
