Matec has developed a wide knowledge in the aggregates sector, as our machines for the water treatment were born to work with aggregates, materials which are not easy to handle. This is why we created a range of machines to wash aggregates, to manage the whole process, and to guarantee the best output from the washing system and the water treatment plants.
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.
Recovery and storage of these materials, which must be disposed of with excavators, trucks and personnel at a later stage, have significant costs for aggregate production industry, also due to the fact that it is necessary to dedicate a large area to these operations.
Matec 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.
Aggregates generally include sand, gravel, expanded clay, vermiculite, and perlite, and also any crushed material used in building construction. They can be found in composite materials, such as cement and bituminous conglomerates and plasters. Sedimentary rocks: Chedmical (Limestone, Dolostone, Evaporites), Clastic (Conglomerate, Breccia, Sandstone, Siltstone, Mudstone, Shale) Biologic (Coal, Chert); Igneous rocks: Intrusive (Gabbro, Diorite, Granodiorite, granite), Extrusive (Basalt, Andesite, Dacite, Rhyolite); Metamorphic rocks: Foliated (Slate, Schist, Gneiss), Non-foliated (Quartzite, Marble).
