Recovering gravel from excavated soil
The recycling of excavated soil has significant environmental and economic benefits. Depending on the content, different methods can be used to maximize recycling and transform a waste or fill material into new high quality products.
It is often possible to recycle stone, soil, wood, gravel and metal from excavated materials that do not contain environmentally harmful substances, thus reducing the use of virgin products.
Analysis of the excavated material is crucial
It is important to analyze the content of the excavated material when choosing a recycling method. If they are contaminated, it is often possible to enrich the contamination so that only a small part needs to be landfilled or destroyed. The analysis is important because some contaminants can lead to damage and pollution in the area.
Contaminated gravel pits
In the past, many operators have found it difficult to recover all the material in a gravel pit, especially the surface layers that are contaminated by the roots of the vegetation overlying the deposit. Particularly in shallow quarries, a lot of material is wasted. In addition, it may also be necessary to separate wood from crushed rock, e.g. crushed from construction rock that has been contaminated with wood or roots.
Many quarry owners have large stocks of material that cannot be delivered for concrete production, but it is possible to screen out unwanted contaminants. Today we can deliver a very well-functioning solution after several years of successful projects in this area.
Gravel recycling with windshifter
Today, we have nearly 100 wind shifters on the Swedish market, primarily in the recycling industry. the wind shifter not originally the wind shifter to handle natural gravel, but this application emerged after several customers discovered its potential. This demonstrates the flexibility of our in-house developed products.
the wind shifter of blowing away even relatively large pieces of material. When excavating old landfills, it has been possible to separate out material up to 0.5 meters in size without any problems.
With a windshifter it is possible to recycle natural gravel, crushed rock and waste sand in an efficient way.
Recycling of waste sand
the wind shifter also the wind shifter to blow away other lighter materials, such as plastic. Therefore, it can also be used torecover road sand. This allows the road sand to be reused the next time instead of being sent to a landfill. This is both more cost-effective and better for the environment.
Natural gravel and concrete production
Sticks, roots and other materials found in natural gravel, or for that matter in crushed rock, cause problems for those who want to use the gravel for concrete production and other purposes. In concrete production, for example, this causes problems as the contaminants float up into the finished concrete.
