A sag mill trommel screen lets you control the true discharge size of your sag mill or the transfer size to the downstream ball mill circuit.A well sized trommel should not let rocks pass to the ball mill if they are to be than say 58 or 16mm in the image case below, strangely enough, is.
Mobile Mineral Processing Equipment: The State Of The
Enter a ball mill. Indeed, if a SAG mill discharge screen or trommel has 12.7 mm square openings, the top size of material moving forward to the ball mill will be 12 mm and the P 80 of the SAG mill discharge will be in the order of 4 to 6 mm, based on a normal relationship of screen opening to product size. According to Bond’s ball mill.
- FL 280 TPH Cement Mill (Roller Press with Ball Mill supplied by Polysius) The circuit has a roller press with two horizontal separators that equally shares the common work of separating fines and sending the rejects to the Roller Press. Bin. 3.

7. Product P80 of any intermediate HPGR circuit ahead of the tumbling mill stage(s) ( m) 8. Product P80 of the tumbling mill stage(s) ( m) •If there are multiple stages of grinding (e.g., SAG milling followed by ball milling), only the P80 of the product of the final milling stage is required. In addition to the above data, a representative.
Jan 01, 2016 Given that mills are charged to the target ball charge with reasonably sized media, and the feed to the ball-mill circuit is not so coarse as to cause constant scatting, the key to efficient ball-mill circuit operation is efficient classifier operation. The standard classifier for ball-mill circuits is.
How A Separator Works In Cement Mill
Jul 24, 2017 Excess capacity in the HPGR circuit will now be used to produce a ball mill feed product of approximately P 80 1 8 (nominally 3.5 mm), a 42 reduction from past studies. Due to the final product size, wet screening will be incorporated and the HPGR crusher circuit product will now report to a sump and cyclone bank.
Similar results have been seen consistently across all the surveys where this approach has been used, including circuits with AG mills, pebble mills, HPGR, stirred mills and ball mills with fine screens. Figure 2 - Comparison of the OWi and SSE75 of the SAG and ball mill for 10 surveys conducted on the same circuit at different times.

HPGR crushing may provide a profitable alternative or addition to a grinding circuit allowing the crushed pebbles to be bled to the subsequent downstream ball mill grinding and beneficiation.
Oct 23, 2015 The comminution efficiency of a HPGR is better than ball mills such that it consumes 30–50 of the specific energy as compared to a ball mill. Four circuit configurations of HPGR can be used in grinding of raw materials, clinker and slag such as Pre-grinding unit upstream of a ball mill. Hybrid grinding. Semifinish grinding.

Our wet Ball Mill griding media reject (scats) from the trommel screen is an odd shape ( see photo attached). I’m not use to this wear shape of grinding media in a ball mill. Normal wear of grinding media in my experience is down from a spherical t.
The mill discharge passes through a wet magnetic separator for further upgrading and also rejection of additional non-magnetic tailing. The ball mill and magnetic cleaner and cyclone all in closed circuit produce an iron enriched magnetic product 85 to 90 minus 325 mesh which is usually the case on finely disseminated taconites.
