Coarse ore particle pass through the trommel and are returned to the mill as cyclone underflow for regrinding. A few coarse ore particles may report to waste with the ball scats. However, if the ball mill is well operated, only very small quantities of large ore particles should reach the trommel as they should not have been fed to the ball mill.

How Coarse can Ball Mill Feed be
If using 3.5-4" media - high wear on liners and a high percentage of ball scats / broken balls. Another option may to consider scrapping the tertiary, and perhaps even secondary crushers (depending on Primary crusher CSS) plus screening / scalping capacities) and using HPGR as secondary crushing / primary grinding before feeding to the Ball mill.

SAG Mill Discharge Scats – Ball Chips
You may find more information regarding the SAG discharge if you search them as "scats" (broken ball chips). Safety Notes; they result from internal stresses in the balls impact and heat energy in the SAG mill causing a Martensite transformation in the ball (Crystals form in the metal) and they have a potential to rupture with very sharp edges.

Addition of pebbles to a ball-mill to improve grinding …
The experiments of ball-milling with scats proved that large balls eliminate scats rapidly. Therefore when composite secondary milling is applied, the combination of a high surface wear rate and impact breakage (caused by large balls) should limit the accumulation of scats, depending upon the feed rate of scats and generation of pebble cores.

The effect of scats on ball-mill productivity was tested and it was concluded that scats may not have an adverse effect on productivity in secondary ball-mills and composite mills, if large balls are present. The use of a trommel on the ball-mill is suggested to solve related problems in the classification circuit.
