Starkey Associates uses the patented SAGDesign technology to calculate accurate mill sizes from measurements on a client''s own ore samples. SAGDesign technology has become a standard for 21 st century grinding circuit design for the following reasons: Precisely measures SAG and ball mill .
Ball Mill Design. A survey of Australian processing plants revealed a maximum ball mill diameter of meters and length of meters (Morrell, 1996). Autogenous mills range up to 12 meters in diameter. The lengthtodiameter ratios in the previous table are for normal applications.
The SAG mill product is then crushed to passing mm and is subjected to the Bond ball mill work index (S dBWI) grindability test to provide the total pinion energy at the specified grind size for mill design purposes, herein reffered to as micro ore hardness. The full SAGDesign test produces the SAG grindability (W SDT) and the Ball Mill

ABSTRACT This paper discusses the process design and layout of the Constancia Project comminution circuit. The circuit consists of a 60 x 113 primary crusher, two 16 MW SAG mills and two 16 MW ball mills.
is home to a collection of both free and subscriptionbased calculation tools to aid metallurgical process engineers perform comminution calculations. Grinding circuit design tools, including for SAG millball mill circuits, and geometallurgy energy models are available to subscribers.
The design of such circuits is complicated by the typical powerbased models used for conceptual design being calibrated to a twostage circuit with AG or SAG mill product being passed to a pebble mill or ball mill stage for finished grinding. The twostage circuit includes a "transfer size"

Mill Power Draw Models. The mill power draw models are used to predict how much power will be consumed by a particular type of mill, mill geometry and set of mill operating conditions. This power is transferred to the ore and used to predict the throughput when combined with the specific energy consumption models.
