When a rock has values in it, it''s then called ore. In order to liberate the minerals, it needs to be crushed down. In days of yore, a stamp mill was the primary form of crushing rock, but in the modern world, there are jaw crushers, impact mills and gyrator crushers, as well as ball mills. They all have their own pros and cons -- and price tags.

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

Gold flotation. Flotation process is widely used for lode gold processing. In most cases, the flotation method has a good effect in sulfide-containing gold ore with high floatability. In addition, the flotation process is also used for polymetallic gold-bearing ores such as gold-copper, gold-lead, gold-copper-lead-zinc-sulfur ore.

The ball mill rolls grinding media together with the ore, as the ore grinds, these balls initially 5-10 cm in diameter but gradually wear out. Grinding is always carried out under wet conditions, with about 70% solid mixture in water. This procedure maximizes ore production and minimizes power consumption.

If the coarse feed size is reduced, the circuit efficiency will approach that of the stage-crush and ball mill circuit. Hence, if the JKDropWeight test Axb parameters (a measure of rock competency) are less than about 40, then secondary crushing is worth considering.

Ball mills are characterized by their smaller (comparatively) diameter and longer length, and often have a length 1.5 to 2.5 times the diameter. The feed is at one end of the cylinder and the discharge is at the other. Small versions of ball mills can be found in laboratories where they are used for grinding sample material for quality assurance.
