When is HPGR better than Ball Mill. HPGR is typically used in a thirdstage or fourthstage crushing application ahead of grinding. You could always try to build a circuit doing 45 µm classification, but I suspect your circulating load would be overwhelming. Most HPGR applications in hard rock mining achieve 3000 µm to 7000 µm product

Rock Crusher History. History tells us, it was in 1830, the first US patent was issued on a rock crushing machine. It covered a device which, in a crude way, incorporated the drop hammer principle later used in the famous stamp mill, whose history is so intimately linked with that of the golden age of mining. In 1840, another patent was issued ...

This painting shows the prominence of a stamp mill (the white building in the center) in mechanized mining operations. Montague, c. 1986 by Joseph Purcell. MOI: The earliest gold mining was done by hand, using a hammer and a pick or a gold pan. The first use of machinery in the gold rush was in the 1860s at an underground mine in Tangier.

The ore undergoes primary crushing at the mine, before being delivered by ore passes to the mill complex for further crushing, grinding and flotation. Grasberg's milling and concentrating complex is the largest in the world, with four crushers and two giant semiautogenous grinding (SAG) units processing a daily average of 240,000t of ore.

Description; A stamp mill consists of a set of heavy steel (ironshod wood in some cases) stamps, loosely held vertically in a frame, in which the stamps can slide up and down. They are lifted by cams on a horizontal rotating shaft. As the cam moves from under the stamp, the stamp falls onto the ore below, crushing the rock, and the lifting ...

Step 1: Milling. When ore enters the plant from underground it first needs to be milled to reduce its size so that the gold is liberated from the host rock. South Deep's milling circuit consists of a singlestage semiautogenous grinding mill (SAG) and a pebble crusher for primary milling, followed by secondary milling using two overflow ball ...
