AG/SAG mills are often the optimum solution for wet grinding (achieved in a slurry 50 to 80 percent solids). AG/SAG mills can accomplish the same size reduction work as two or stages of crushing and screening, a rod mill, and some or all of the work done by a ball mill.
While AG mills operate without a ball charge, SAG mills use a grinding media charge of normally 3 % 12 % for comminuting the feed material.
The original ball load in the mill was 6614 lb. (3000 kg.) and the load at the end of the 694 hr. was 6338 lb. (2874.8 kg.). During this time, 590 lb. (267.6 kg.) of balls less than 3 in. (76.2 mm.) in diameter were discarded from the mill. The screen analysis of the ball charge at the end of
PERFORMANCE ENHANCMENT TOOLS FOR GRINDING MILLS 103 The need for new instruments grinding media trajectories, as shown in Figure 1. By Operation of large SAG mills requires a change in the conceptual approach to grinding processes.
Common convention generally refers to high aspect ratio mills as SAG mills (with diameter to effective grinding length ratios of 31 to 11), low aspect ratio mills (generally, a mill with a significantly longer length than diameter) are also worth noting.
Sino Grinding designs and manufacturers SAG mill ball mill grinding media for site specific grinding environments. Our grinding media is world class and cost effective.
tumbling media grinding mills because a large component of the power draw of these . operating at less than design capacity, a much more serious effect was the . hydrocyclone/secondary mill layout to drastically reduce circulating loads.
Grinding media, the objects used to refine material and reduce particle size, are available in a wide range of shapes, sizes and materials to meet an equally wide range of grinding and milling needs.

SAG is an acronym for Semi Autogenous Grinding. SAG mills are autogenous mills but use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21%. The largest SAG mill is 42' (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor.
Cast iron grinding media for the production this type of the grinding media used cast iron as gray and white. The ceramic grinding media this type of the grinding media, as the name suggests, is made of ceramic and used mainly in small sized mills (about 50 liters) in
media in the mill by looking at the mill grinding efficiency. At that time, it was difficult to acquire a lot of valuable information as robustness in an aggressive environment was not assured. Twenty years later, the Sensomag is able to show this interaction by looking on the pulp position angle and media angle.

Oct 28, 2010 of Autogenous (AG), Semi Autogenous (SAG) and Media mills. AG equipment, unlike the other two types uses no added grinding media, while SAG, Ball and Rod mills uses some percentage of foreign media to facilitate size reduction. According to Han (2003), regardless of the type of tumbling mill
Grinding media wears and reduces in size at a rate dependent on the surface hardness, density and composition of the ore. Ball wear is directly proportional to surface area per unit mass and thus inversely proportional to ball diameter.
Our steel forged grinding balls in the diameter range of 3.5quot; 6quot; are classified as SAG balls and are primarily used in SAG mill operations. Quality Standards Products manufactured in China. Certified under ISO 9001 Quality Standard and ISO 14001 Environmental Standard.
