Title The characteristics of vertical roller mill
Description The characteristics of this kind of deposit are soft, shallow burial depth, generally 5~10m, some 20~30m; the thickness of gold-bearing deposit is generally 1~5m, individual up to 10m; The belt width is 50~300m on average, and the length can reach several kilometers or tens of kilometers; the slope of the vertical roller mill is very small, generally 0.002~0.02. The gold ore is generally simple in composition, shape mostly in granular or scaly, and the particle size is usually 0.5~2mm, average density about 17.5~18.0g/cm3. According to the particle size, gold can be divided into a large piece of gold (greater than 5mm), coarse gold (5~1.65mm), medium gold (1.65~0.83mm), fine gold (0.83~0.42mm), extra fine gold (0.42~). 0.15mm) and the most particulate gold (or floating gold, less than 0.15mm). Gold-bearing quartz vein oreThe basic composition of ore is quartz, with a content of more than 90%, and almost no heavy metal sulfide. Natural gold is mostly filled in the crack and cleavage surface of quartz in coarse grains, or disseminated in quartz veins in fine grains. Gold is easy to dissociate after crushing and grinding.
