Korea builds their first IGCC plant with proven Loesche technology. Loesche signed a contract to supply two LM 43.4 D coal mills for Korea's first 300 MW IGCC demonstration plant in Taean. The Loesche mills will grind, dry, and classify a coal and additive mixture to produce 95 tons/hour of raw material for the plant's gasification process.

2. Loesche wins order for supply of Coal Milling
and Drying system for Korea’s first IGCC demon-
stration plant project
In March 2012, Loesche signed a contract with Doosan
Heavy Industries & Construction for the supply of
two Loesche coal mills type LM 43.4 D for the coal-
based integrated gasification combined cycle (IGCC)
power plant (1 x 300 MW, net) to be built in Taean,
South Korea.
The scope of supply comprises the complete equip-
ment from the raw coal feeding system to the product
bag filter, including the Loesche grinding mills and Loe-
sche hot gas generators, flaps, fans, electrical drives,
and Loesche automation system.
The throughput of the Loesche four roller grinding mill
type LM 43.4 D amounts to 95 t/h coal with additives
(dry-base) based on the fineness of 10 % residue on 90
microns sieve. In this case the Loesche coal mill type
LM 43.4 D simultaneously grinds, dries, and classifies
a mixture of coal and additives with more than 25 %
moisture. The mill main drive power rating amounts to
1,600 kW.
