اقرأ أكثرUnderstanding the SAG Mill in Copper Ore Mining Process
A SAG mill, or semi-autogenous grinding mill, is a type of machine used in mining and mineral processing operations. It uses the crushing and grinding action of rocks to reduce materials such as copper ore into smaller pieces for further processing. Unlike traditional mills that rely on steel balls or other media to break down materials, SAG ...

mm (8 in.) and water enter the feed end of a SAG mill through a feed chute; the ore is milled in the shell and milled product exits through grates and pulp lifters at the discharge end (Fig. 1). The discharge is screened and the undersize, typically less than 12 mm (0.5 in.), provides ball mill feed and the oversize is returned for further milling.

The SAGDesign test and design equations give the energy to grind an ore from 80% passing 152 mm to 80% passing 1.7 mm. Since this transfer size is fine enough feed for a ball mill no ball milling inefficiencies will occur. A 5 mm closing screen will deliver this approximate size of SAG ground product to the ball mill.

This is the reason that the size of the electric motor for a primary crusher, that has a production rate of five hundred tons per hour, is so much smaller than the horse power of a rod mill that can only grind three hundred tons per hour. In the harder ore there are less of these fracture lines created with each size reduction.

Feed Size, F80: Primary crushed ore is mandatory to feed any SAG mill. Typical feed size range is 80% passing 130 to 160 mm. Softer ores will be a little finer but the finer size is not sustainable when the ore becomes hard. Pre-crushing to finer sizes enhances throughput as does crushing of pebbles from the SAG mill (usually minus 60 mm).
