The company Loesche in Düsseldorf is pleased to receive a follow-up contract for a coal mill, of the type LM 28.3 D, which is the same type of coal mill already successfully deployed by RWE Power AG in Niederaußem. In July 2012, RWE Power in Essen commissioned a new vertical roller mill from Loesche.
"Ahmsa is currently quantifying the reserves of these mines, and is carrying out engineering design [work]," he said. The $1.5 billion Fénix project comprises a 1.46-million-tpy blast furnace, a 1.2-million-tpy electric arc furnace, a 1.2-million-tpy slab caster and a 1-million-tpy plate mill.
The dry coal is then transferred to the pulverising mill to pulverise the coal. The primary air is supplied to the mill to carry the pulverised coal to the burner where the secondary air is mixed to have complete combustion of the fuel. Advantages. The layout is simple. Easy in operation. Less space is required. Cheaper.

The BTM is a low-speed mill that primarily grinds coal by impact and attrition. The VRM is a medium- speed mill that grinds coal by compression and, because of the low coal inventory in the mill and flat grinding surfaces, develops shearing action as well. For both mills a constant centrifugal force is maintained. The speed
Newmont Goldcorp has announced it has safely started up production at the Peñasquito mine in Mexico following the lifting of the illegal blockade on October 8.

This will be elevated (naturally being above the tunnel tracks), and it will be an operational coal mine. The coal mine will be in the center of the loop at the top of the mountain. Naturally there will be coal mining buildings there but I haven't drawn them up yet either. The picture below shows the tunnel track with the coal mine module removed.
