AGGREGATES SAND GRAVEL
Aggregates like gravel and in particular sand, because of their applications, need to be washed to recover fine particles and eliminate the silt which adheres to their surfaces. Usually, the water used for sand washing can be recycled by using settling ponds in which heavier particles settle down and where they are collected from the bottom to be stocked.
Building material producers recover it with a settling tank and filter press technologies. The goal is to save space as well as recycle as much water as possible.
JWK filter press allows to get rid of settling ponds and produces dry cakes easy to stock and dispose of, it also recovers water which is particularly important in dry areas.
The recovery of about 90% of fines over 75 microns, the almost total elimination of clay and lime impurities, the recovery of materials with a residual moisture below 15% and the reduction of the solids present in the discharge water with reduction of materials to be treated in the water treatment plants.
