Sep 23, 2014· Fimiston mill foundations – Mill and soil not shown for clarity. Red Dog Mine One of the more interesting projects that we have been involved with was the Red Dog Mine SAG mill foundations. The mills are supported on steel supports rather than concrete. The mills operated for many years without issue and then began to vibrate excessively.
motor, mill, bearings and foundation – must be adjusted to get a sufficient safety margin against inadmissible deformation. On the other side the interacting forces between the components must be kept to a mini-mum for economic design. Incidentally, large SAG mills installed as on date are located mostly in critical seis-mic zones.

The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum 'chunk size', product size as P80 and maximum and finally the type of circuit open/closed ...
SAG mills mimic the same shortcoming. It follows that in order to obtain the specifi c energy (SE) to achieve a certain transfer size, based on the 80 per cent passing value, an ineffi ciency factor must be applied to the SE of single stage ball mills, rod mills or AG/SAG mills when calculating power according to the Bond Third Theory method.
