Oct 11, 2019nbsp018332sulphide copper-gold ores are usually sorted by flotation. the standard comminution process to grind the ore to flotation fineness, mostly consists of coarse crushing followed by sag milling or wet ball mill circuits, or alternatively multiple stage crushing followed by rod and ball milling.
The mill can be used in a closed circuit, with a spiral classifier, screen or cyclones or as a single pass grinding mill. the spiral classifier is popular in pilot plant grinding due to the ease in which the oversize is returned to the mill when a specific grind size is your target. the mill is capable of both wet and dry grinding. sepors 16 ...
Ag mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill and some or all of the work done by a ball mill. ag mills are also an optimum solution for wet grinding since crushing and screening in these cases can be difficult, if not impossible.
Citation needed but note that the term rod mill is also used as a synonym for a slitting mill, which makes rods of iron or other metal. rod mills are less common than ball mills for grinding minerals. the rods used in the mill, usually a high carbon steel, can vary in both the length and the diameter. get price
Jun 11, 2019nbsp018332the longer the residual grind time, the finer the grind. on large mills, dry grinding require about 30 more power than wet grinding. depending on the type of mill, liners on large mills are made of replaceable hard metal alloys such as cr-mo, ni-cr iron, cr-mo steel and mn steel. flint and pebble mills normally use a ceramic liner.
Rod mill the grinding media in a rod mill are long rods of particular material which grind the ore by tumbling within the mill. the grinding action is by line contact between the long rods. there is a very minimal slime production since rods tumble and spin in roughly parallel alignment and produce size reduction of coarse ores efficiently.
