In the order you have listed a ball mill can fine grind down to 400 mesh if needed, a rod mill will efficiently grind to 150200 mesh range, and a roll mill can do a - 100 mesh.The ball and rod mills are similar in appearence, as a large rotating lined cylindrical tube filled with either metal balls or long rods used as the grinding medium.
Get PriceBall mill vs rod mill.The working principle is basically the same.Regardless of the ball mill or the rod mill, when the cylinder rotates, the grinding media ball or rod installed in the cylinder body are lifted to a certain height, and then they are thrown at a certain linear velocity, so the grinding media causes some impact.
In the ball mill, commonly used have the lattice ball mill and overflow ball mill named from different drainage structure, and the rod mill does not use the grid plate drainore, only overflow type and opening type two kinds, the diameter of the hollow shaft at the drainage and end is generally larger than the same specification ball mill.
In a ball mill the actual balls in the machine need to cascade in order for the grinding to be accomplished.Because of this more energy is needed to power up a ball press as opposed to a rod press.Mclaughlin, kevin comparing used ball mills vs used rod mills.Comparing used ball mills vs used rod mills ezinearticles.
Rod mill definition is - a mill that produces rods of steel or other metal.
What is the difference of rod mill and ball mill rod mill and ball mill may be only one word difference in the name, but in fact, there was a striking internal differences.Rod mill , as the name suggests, is to rely on rod bars for the material grinding,and wet overflow is a generally used material way.Rod mill is generally used as a grinding equipment in the artificial stone sand.
Measuring ore grindability in rod mills.The bond rod mill work index is a measure of the resistance of the material to grinding in a rod mill.It can be used to determine the grinding power required for a given throughput of material under rod mill grinding conditions.It is a locked cycle test conducted in closed circuit with a laboratory.
Bond rod mill grindability test.Grinding solutions can carry out bond rod mill work index tests to determine the energy requirements for milling ore in a rod mill.The test requires a minimum of 20kg of -12.Closing screen sizes typically range from 4.Abrasion index test.
