04/07/2019 Autogenous Grinding Mechanisms. Autogenous grinding is at present carried out in tumbling mills of the same types as used in ball mill grinding. The similarities in equipment and procedure have led to the commonly held assumption that the grinding mechanisms are the same in the two processes, with the coarse part of the ore charge taking over the function of the ball charge.

Autogenous grinding mechanism ideenausstahl.ch. Semiautogenous grinding uses a minimal ball charge in the range of 615% while autogenous grinding uses ore only. SAG and AG Mills operate by lifting ore/grinding media and dropping it on the operating bed of the mill charge. High impacts from lifting ore and media promote impact breakage which is the primary mechanism for size reduction in

20/07/2017 Autogenous Grinding Circuits. When an ore is hard and competent, there is always the possibility that it would make good “pebbles” which could be used for fine grinding media. Different methods that have been tried using combinations of autogenous, semi-autogenous, pebble and/or ball mills. The flowsheets shown are typical of the properties listed but a specific property may be using a

15/1/2019· Autogenous grinding mechanism is proposed in this paper to have a grinding where the grinding media is itself. In this process, the harder fraction of coal is not grinded and this will enhance the breakage through grain boundaries due to bond strength [22,23].]. Get Price .

INVESTIGATIONS OF BREAKAGE MECHANISMS IN AUTOGENOUS GRINDING SUKANYA TANGSRIPONGKUL CHEMICAL ENGINEERING DEPARTMENT FACULTY OF ENGINEERING KING MONGKUT'S INSTITUTE OF TECHNOLOGY THONBURI SUMMARY The kinetics of breakage of Colorodo Quartz for large lumps was investigated in terms of three breakage mechanisms: abrasion,
Grinding (AG) mills), or the combination of the two (Semi-Autogenous Grinding (SAG) mills) to fracture rock using the breakage mechanisms of impact and abrasion. The rotation of these large, cylindrical mills, coupled with the low probability of ball particle collisions, results in a high demand for energy in the grinding process. Although their established circuit design and ability to

autogenous grinding mechanism. In either case, grinding effectiveness is suboptimal and production cannot be maximized. To maximize produc-tion, it is necessary to maintain the mill load at the point of optimum grinding. Although the mill weight provides. Get Price. PAI SAG Mill Training YouTube .

The operation and mechanism of grinding and size reduction is explained with the help of solved mathematical examples. Computation for determining SAG Get Price. Mill grinding
In most mining operations, the grinding is performed in tumbling mills utilising loose grinding media, lifted by the rotation of the drum to break the ore lumps by different breakage mechanisms. The grinding media can be steel balls or -rods or the ore itself as in autogenous grinding. Grinding is usually performed wet and when the mill is rotated ore and water, the mill charge, is intimately

01/09/1989 In autogenous grinding Digre estimates that attri- tion and impact are only 20-50% of total and abrasion is the main mode of grinding. Coarse lumps are "producing" fines by different mechanisms. First they might have such a energy level in hitting the toe that they break them- selves by crack propagation. Secondly if the energy is not enough to break them, there is always a local stress

autogenous grinding mechanisms. main components of a semi autogenous grinding mill. Autogenous grinding (AG) and semi-autogenous grinding (SAG) mills use the material to be ground as the grinding media. Autogenous grinding mills use larger rocks to impact and break smaller rocks as the mill rotates. Semi-autogenous mills are basically the same autogenous mills but with the

27/02/2017 The dominant wear mechanisms in grinding (ball milling process) are high-stress abrasion and erosion–corrosion. In autogenous and semi-autogenous mills, high impact abrasive wear induced by ball contacts is a major wear mechanism. Thus, ball milling of iron ore involves severe mechanical interactions between balls and between balls, iron ores and liners
