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.
The designs of autogenous and semiautogenous (SAG) grindings mills are described followed by the description of their methods of operation in grinding circuits involving crushers and ball mills. Methods of estimating SAG mill volumes, mill charges, feed size and power consumptions and optimum speeds of rotation during operation are described.
The grinding circuit for the Copper Mountain project consists of one FL SAG mill and two FL ball mills. Figure 1 Overview grinding circuit The Copper Mountain SAG mill is 10363 mm [34 feet] in diameter and 6096 mm [20 feet] long. It is a grate discharge mill with an inside diameter of 10363 mm [34 feet] and a grinding length of 5334

SAG system composed by SAG Mill, Stator and Foundation the spatial mass and stiffness distributions of all components, both in transient and steady (operational) states, the electromagnetic and/or mechanical forces, the presence of highly complex boundary conditions and interfaces between the involved components, etc.
Wind turbine tower is a typical highrise structure building.. The average wind tower height on earth is around 90m – 130m. The wind turbine foundation bears the load transmitted from the wind turbine tower and the turbine on the top, especially the huge overturning moments.. For onshore wind turbine tower, there are basically 5 common types of wind tower foundations: .
differences in stresses and forces on the GMD and foundation are shown based on a turning and stopped mill simulation during an earthquake. The results demonstrate the need to maintain active and operating earthquake detection systems. Aside from detecting an earthquake''s magnitude, the sensor information can also be used to
