There are others which use just the force of the ore falling on itself to break it down into a smaller size. These are known as Autogenous or AG mills. Another common mill type uses a combination of both autogenous grinding and ball mill grinding—these mills

WhatsApp: +86 18838072829Hello everyone, 1. a 40 000 tpd plant with a 15 MW primary SAG mill and 2 pcs 10 MW secondary ball mill. If you try to change the H/C feed pump without stopping or just during a short shut down of the grinding line, you may not get a single drop of slurry into the stand by pump because the feed sump is half full of ball scrap and coarse rock, blocking the pump inlet pipe of the standby pump.
WhatsApp: +86 18838072829One of our Ball Mills keeps losing pressure on the high pressure pump. It will run fine when starting the Mill and suddenly after a while sometimes 1hrs the pumps will loose pressure. We have just grinded the journal and installed new white metal bearings. After startup this afternoon after about 1hrs the pumps low and high just lost pressure.
