rock crushers for commercial gold mining operations
Jan 23, 2017 Rock crushers are machine build to break large rocks into much smaller rocks, gravel, or sometimes rock dust. They are an important tool for most commercial mining operations. Rock crushers usually hold the rocks to be crushed in between two solid surfaces and apply a force that forces the molecule of the materials to separate or change alignment. Oct 06, 2014 the rocks pre crushed ready to go in the crusher the crushed rock some little chunky bits of gold . Now after crushing some of these rocks I have found that some have good bits of colour in them and others are completely barren. I have to sample and figure out which ones by appearance have the colour and which ones are worthless.
