Optimizing your SAG mill operation
Similar to the impeller design affecting pump capacity, the pulp lifter design affects the discharge capacity (or mill throughput) of AG and SAG grinding mills. Generally, the discharge from AG/SAG mills consists of one or both of the following components: slurry (water and finer particles) and pebbles (20-100 mm).

Manual design of SAG/ball/rod mill foundations
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 be detrimental (ie: increase client expectations).

Ball Mill Maintenance & Installation Procedure
Grinding Mill FOUNDATION. Adequate foundations for any heavy equipment, and in particular Marcy grinding mills, are extremely important to assure proper operation of that equipment. Any slight settling of foundations will cause bearing and gear misalignment, resulting in excessive wear and higher maintenance costs.

Semi-autogenous grinding (SAG) mill liner design and development
SAG mill liner development draws primarily on practical experience from SAG milling operations supported by computer-based modeling of charge motion in SAG mills and on established good design practice. Liner design needs to respond to the process aspects of mill liner action that are critical to good SAG mill performance, i.e.,

Leaders in Comminution Design
John Starkey, P. Eng. has worked in SAG mill hardness testing since 1964 where he worked as pilot plant engineer for A. MacPherson’s projects. He invented the SPI and SAGDesign tests. The latter is now acknowledged by our clients to be a world-class method for grinding circuit design, and is accepted by our peers as a standard for ore

SAG Mill Grinding Circuit Design
Traditionally, many engineers approached SAG circuit design as a division of the total power between the SAG circuit and ball-mill circuit, often at an arbitrary power split. If done without due consideration to ore characteristics, benchmarks against comparable operating circuits, and other aspects of detailed design (including steady-state

Grinding Mill Foundations
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.

Rely on our proven track record of AG and SAG Mill superiority. Since the early 1980s, we have been designing and manufacturing Semi Autogenous Mill (SAG Mill) and Autogenous Mill (AG Mill) under the Fuller-Traylor brand. Semi-autogenous grinding uses a minimal ball charge in the range of 6-15% while autogenous grinding uses ore only.
