Coal mills
Since 1925 - for over 80 years - we have been concerned with pulverized fuel
for kiln and boiler firing. For all grades - hard coal, woody lignite and lignite as well
as anthracite coal and petroleum coke - we design and build, on turnkey basis, safe and
reliable dry-grinding installations for pressure, suction or inert operation, equipped
with Loesche pressure-shock-resistant grinding mills.

The Loesche coal mill is a modular and flexible design. The modular design allows
a 2, 3 or 4 roller mill to be custom built to suit the required output. This saves time and
money from the design to the erection stage.
The ground product quality is consistently high irrespective of plant capacity. During start,
stop and full or partial-load operation, no contact takes place between the grinding elements
to disturb the vibration free running. A flat grinding track - individually guided - adjustable
rollers and a roller swing-out device for servicing ensure that the Loesche coal mill achieves
almost 100% availability. The service for the mill is easy to maintain.
The drawing shows the operating principle of the Loesche coal mill in the present
design for a production capacity up to 200 t/h.
