AG and SAG mills are now the primary unit operation for the majority of large grinding circuits, and form the basis for a variety of circuit configurations. SAG circuits are common in the industry based on: High single-line capacities (leading to capital efficiency) The ability to mill a broad range of ore types in various circuit configurations, with reduced numbers of unit operations (and a
Here is a list of the SAG Mill Manufacturers & Suppliers I know: FLSmidth liming Outotec CITIC-Heavy Industries Co. Ltd Thyssenkrupp Polysius Farnell-Thompson TyazhMash 911Metallurgy A highlight of SAG milling has been the collaboration between grinding mill manufacturers and mining companies. Experimental work on very large mills is difficult, expensive, and potentially catastrophic if it
If the SAG mill is not intended to be the rate-limiting step in a process plant, then it is best to adjust the SAG load (and power) to hold a constant tonnage to satisfy another constraint elsewhere. Underground mines are an example: the hoisting capacity of the mine shaft is the rate-limiting step in the process, and the SAG mill must adapt to what the shaft can supply. So yes, there are

Gross power No load power Net power drawn by the charge (8.13) The net power is calculated from Net power KD2.5L e! c./ Watts (8.14) In equation 8.14, D is the diameter inside the mill liners and Le is the effective length of the mill including the
Mineral processing typically involves the crushing and grinding of hard rock ore. Crushed ore is introduced to semi-autogenous grinding (SAG) mills, also known as primary mills, where grinding media is released like hammers to assist in the ore cracking / grinding process. The mix of media and ore rises and falls in the mill like clothes in a
Is it advisable to use a SAG mill for small, say 2000 TPD concentrator operations? The processing, in this case, is a complex zinc/tin mineral and we are afraid a SAG would P80 produces too much fines (since the tin is to soft brittles) (tin cassiterite).The mineral is marmatite and casiteritre
Semi-autogenous mills or SAG mills, as they are often called, can accomplish the same size reduction work as two or three stages of crushing and screening. Often used in grinding at modern mineral processing plants, SAG mills reduce the material directly to the desired final size or prepare it for the following grinding stages.

No discussion of SAG milling would be complete without mention of relining. Unlike a concentrator with multiple grinding lines, conducting SAG mill maintenance shuts down an entire concentrator, so there is a tremendous focus on minimizing required maintenance time; the reline timeline often represents the critical path of a shutdown (but typically does not dominate a shutdown in terms of

Orway Mineral Consultants (OMC) is a Perth and Toronto based metallurgical consultancy providing a range of services to the mineral processing community. The consultancy, established in 1983, has a reputation for the delivery of high quality studies and practical engineered solutions in the areas of comminution, beneficiation and hydrometallurgy.
Within the mineral processing industry, a range of grinding conditions exists which include semiautogenous grinding (SAG), rod milling, and conventional ball milling. Each of these mill environments presents a unique environment for grinding media, requiring the application of specific physical and stone properties for optimum grinding media performance.
Gold processing 101 (SAG) mill and ball mill. The latter is preferred for wet sticky ores to minimise transfer point chute blockages, and can offer savings in both capital costs and long-term operating and maintenance costs. However, the SAG route is more power-intensive and, for very hard ores, comes with some process risk in predicting performance. More recently, a hybrid solution has
