Nov 26, 2019 Since the power of the autogenous tumbling mill is relatively small, it is appropriate to choose dynamic and static pressure bearing. The ball bearing liner is made of lead-based bearing alloy, and the back of the bearing is formed with a waist drum to form a contact centering structure, with the advantages of flexible movement.
Mar 01, 2004 A rock breakage test has been developed that can help predict autogenous AG and semi-autogenous SAG mill performance in situations where only limited quantities of rock samples are available. The test was originally developed to make use of quartered slivered core but whole core, half core and lump material can also be used.

An autogenous mill of ID 6.7 m and an effective grinding length of 2.1 m was fed with ore of SG 3.8 to 20 of its volume. The mill was operated continuously 24 hours per day at 1200 t per day and 75 of the critical speed. The solids in the mill charge were at 80 solids.
Jul 20, 2017 Autogenous plus Pebble Mill are an excellent technique if the ore is uniformly hard and competent but it has not been popular because the porphry copper orebodies do not consistently produce sufficient hard, competent pebbles for the secondary grind. Autogenous plus Ball Mill has been used very infrequently.
Aug 06, 2015 In a autogenous mill the ore is fed directly into the mill from either the primary crusher or the mine itself. The size of the rock will be between four and eight inches. It will be this type of mill that will use a stock pile instead of a bin as fine ore storage. The feed is large enough that moisture and freezing wont bother it.

the mill is used primarily to lift the load medium and charge. Additional power is required to keep the mill rotating. 8.1.3 Power drawn by ball, semi-autogenous and autogenous mills A simplified picture of the mill load is shown in Figure 8.3 Ad this can be used to establish the essential features of a model for mill power.
Autogenous mills use ore exclusively as their grinding media but if hardness and abrasiveness of the ore does not lend itself well to full AG milling then a small charge of steel balls 6 to 15 is added to assist in size reduction. This is known as a Semi-Autogenous SAG mill.
