Metallurgical ContentIntermediate Autogenous GrindingAutogenous Grinding ExplainedTest ConditionsGrinding Characteristics of Short Mill Versus Long MillObservations and Recommendations The third type of mill that I mentioned was an AUTOGENOUS MILL, this type of mill uses a completely different type of grinding media; the rock itself In conventional milling, the ore is crushed to, plus or
The autogenous mill itself is a coarse-grinding device, consisting of tumbling drum with a 25% to 40% volume filling of ore. Metallic or manufactured grinding media is not used. Autogenous mills are fed run-of-mine ore or primary crusher product that is <25 cm (10″). Inside the mill, large pieces break into smaller pieces a few inches in size.

autogenous (SAG) and fully-autogenous (FAG) mills. This is largely because the physical processes of breakage occurring in these mills are more complex than those in it and then use an approximate simplified form of the models to compare the performance of a typical SAG mill design (LID = 0.5) with that of a representative
High-efficiency autogenous mill can realize the second and third stage crushing and screening, and part or all crushing and grinding of rod mill or ball mill. Low power consumption, no dust pollution, less auxiliary equipment, easy production automation, and stable particle size.
Rely on our proven track record of SAG and AG Mill superiority. Since the early 1980s, we have been designing and manufacturing Semi-Autogenous (SAG) and Autogenous (AG) Grinding Mills 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.
The reduction in mill load from 27.59 (pre-TPL™)to 14.46 (post-TPL™) includes the change due to elimination of both flow-back and pebble pooling. The internal dimensions of TPL™ are designed using modelling and simulations to make sure all the particles that are passed ™ IMPROVING AUTOGENOUS/SEMI-AUTOGENOUS GRINDING PERFORMANCE AND
Also, autogenous mills have grate discharges, so as to retain the coarse grinding media in the mill while dispatching the fine particles. The other benefits of using autogenous grinding include reduction of metal wear, and elimination of secondary and tertiary crushing steps. Therefore, autogenous grinding offers more savings in capital and
Apr 01, 1996· It is expected that the equations will be of use to plant/equipment designers and researchers interested in modelling the behaviour of autogenous and semi-autoge- nous mill:~. 1. Introduction The degree to which slurry is held up within autogenous (ag) and semi-autogenous (sag) mills influences their grinding capacity and power draw.
Thus it offers a savings in capital and operating costs. Autogenous mills are available for both wet and dry grinding. The diameter of autogenous mills is normally two to three times the length. The ore charge is usually 25 to 35% of the mill volume.Autogenous mills have grate discharges to retain the coarse grinding media in the mill.
