DUST COLLECTION The dust problem at Wittenoom was the subject of a discussion this morning between Mr. Brisbane Mr. Boyland Mr. Simmons Mr. Dunstan and Mr. Thomas
door closures together Mr. Boyland expressed his appreciation of the
work done in the mine but was very critical of the mill claiming
that the Rotoclone installation was in
his
opinion inadequate
and overloaded and that conditions generally throughout the
plant were excessively dusty
Spillage from the conveyor belts
and the absence of
closures
with the lack of a
regular maintenance schedule appeared to be the main poin te of contention within the plant
28,000 in
To attempt to achieve an immediate improvement
conditions a restriction of throughput has been set down by
the local Mines Inspector setting the rate at 28,000
tons per four weekly period This is understood to refer to
total mill
rather than just the
treatment section and could restrict
something in the order of 1,660 tons
duration of the restriction is for a
any change will be subject to review
or by appeal under Section 22 of the
tonnage entering the our fibre production to
per four weeks The
period of
five weeks and
at the end of that period
Mines Regulations Act
Hunstan possible
ToTo assist in rehabilitating the mill as quickly
as possible it is proposed to send Mr. Dunstan of S.W. Hart &
Co. to Wittenoom on Sunday 10th December to ensure that the
rotoclones are operating to their maximum capacity and efficiency
and to balance the dust circuits within the mill Mr.
will look at presurising the mill during his stay
