Flexible and environmentally friendly.
Koller Transporte-Kies-Erdbau GmbH, a subsidiary of PORR Umwelttechnik GmbH, has operated a highly efficient gravel washing plant since 2010. It has an annual capacity of 300,000t.
The plant enables the company to cater exactly to the client's specifications. For example, all grain sizes from 0.063mm to 90mm are produced. The entire product range is continuously monitored and tested in the course of a CE-certification procedure.
Thanks to optimised water circulation, the plant maintains up to 95% of its process water within the cycle. This means that operations are not only economical, but also environmentally friendly. The latter is also due to the fact that no additives are added to the process water.
Operated night and day.
