The 102 foot high mill is capable of
producing 100,000 tons of asbestos
fibre per year, although this figure has
been exceeded.

The asbestos milling process at Clin-
ton Creek consists of five stages of
fiberization and screening and is based
on the knowledge that asbestos fibre
“fluffs up” when it is separated from its
host rock. As the fibre and rock pass
from screen to screen the fibre tends to
“float” on the surface of the rock. As the
rock and fibre are shaken down to the
end of the screen the rock waste drops
away by gravity and then the fibre is
drawn off by suction.

The mill employs one rockline and
four fibrelines in its milling process. The
rocklines consists of successive
stages of screening, fibre lifting, and
fiberizing in which the longest fibre is
lifted off by suction in the early stages
of production. The long fibre is then
collected and subjected to the CP
grade cleaning process. Intermediate
length fibre is lifted from the second,
third, fourth, and fifth stages of screen-
ing. Itis collected for grading and clean-
ing in the CT grade fibre circuit. The
short fibre is lifted from the fifth, sixth,
and seventh stages of screening and
collected for grading and cleaning in
the CY and CZ grade circuit.
