Possibilities of fine material removal
Summary of bachelor study on "Possibilities of fine material removal". Author: Erki Närep
Limestone is one of the most common minerals in Estonia. It is mainly used as raw material for the production of splinters and cement. The limestone bed consists of upper layers with high quality limestone and lower layers with clay-rich limestone. Producing splinters and cement with a clay-rich limestone requires additional processing, in order to reduce clay content using fine material removal.
Limestone is one of the most common minerals in Estonia. It is mainly used as raw material for the production of splinters and cement. The limestone bed consists of upper layers with high quality limestone and lower layers with clay-rich limestone. Producing splinters and cement with a clay-rich limestone requires additional processing, in order to reduce clay content using fine material removal.
The results showed that the most
effective method is dry sieving, which removed the full percentage of fine
material. Jigging removed 70% and pressure washing removed 29% of the 0-4 mm
sized material. The appropriate equipment for fine material removal is
McLanahan’s Rotary Scrubber, McLanahan’s Log Washer and Haver & Boecker’s
Hydro Clean Washing System.
Dry sieving proved to be the most
effective method. However, it is not industrially applicable due to high time
expenditure and energy consumption. Pressure washing as an independent method
is also not applicable due to low percentage of fine material removal.
Therefore, the most effective industrially applicable method is jigging. The
highest effectiveness would be achieved by combining both, jigging and high
pressure washing (as additional processing), which theoretically should remove
all fine material. Hydro Clean Washing System has the lowest water consumption,
appropriate productivity, low upkeep, it is environment friendly and it uses
the previously mentioned combined method which makes it the best choice for
fine material removal today.
