Grinding Mill Foundations

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.

Manual design of SAG/ball/rod mill foundations

Mar 14, 2007 RE: Manual design of SAG/ball/rod mill foundations youngstructural (Structural) 7 Mar 07 18:27 I have a bit of a long answer here, so I'll give you a synopsis: I don't think an design can be produced manually, and I think a preliminary design could

Autogenous and Semi-Autogenous Mills

Single stage SAG Mills are very beneficial in reducing CAPEX for plants with a staged throughput approach. When future tonnage is to be increased, the SAG Mill can feed downstream ball milling to boost capacity. Fuller-Traylor SAG/AG Mills range in size from 4.3m through 12.2m in diameter with powers as high as 28,000 kW.
