The work has a primary crusher on an open crushing circuit. This is a hammer crusher intended to reduce the run to -250mm.
Furthermore, the mass flow enters a closed sight / crushing circuit, the secondary crusher, which causes the run down to -50 mm.
After the secondary crusher, the ROM is taken into the first wet screen step. Here, -3mm is taken over for classification cyclones while +3 -50 mm enters the hydrocyclone.
The fine substance, -3mm, is split into spiral banks before the coal is dehydrated in a centrifuge.
+3 -50 is also dehydrated in the centrifuge.
The departure is only dehydrated over screeners.
Water is recovered through a thicker cell and continuous filter presses. Departure from the filter presses can be run together with the coal departure or as a separate product.
Both cationic and anionic flocculants are used in the water treatment.
