water addition at cyclone 1 is used to control particle size of the overflow stream of this circuit. in essence this only determines the mass cut to overflow and underflow. with a finer particle size in the overflow, there is thus less material in the overflow. this implies more material in the under-flow, which is the fresh feed to the second ball mill.
a: the ball mill will be performing the particle size reduction, that is the only task the mill has. the cyclone is controlling the efficiency of the mill. generally, cyclones operate in very rough conditions. they receive a lot of material and are not able to look at individual particles. a large volume of particles is continuously coming into the cyclone. therefore, the cyclone has to make a quick decision whether the

the control system of claim 1, with said ball mill grinding circuit being operative in a reversed arrangement such that the new ore material passes to said production cyclone before passing to the ball mill grinding device and said actual load material solids flow is the underflow from said production cyclone.
under normal circumstances, the mass ratio of material to filtrate water entering the ball mill is preferably 1.3-1.5. 4. controlled range of the slurry density. the slurry density is measured on-line by a slurry line installed in front of the inlet of the cyclone.
the ball mill machine is wide accustomed method cement, salt product, building material, refractory material, fertilizer, ceramics, and glass, etc. the ball mill, also known as the rod mill, will work in a dry manner or wet way. you choose the operating way of a little ball mill machine according to your material and discharging way.
also, the uprising velocity in the mill can be controlled by a recycle pump to affect the product size distribution, prevent over grinding, and reduce the circulating load from the cyclone. inquire now; cyclone performance on ball millcyclone overflow product sizing is 80 percent passing 106 µm.the ball mill feed is 60 percent plus 106 µm.
if a ball mill uses little or no water during grinding, it is a ‘dry’ mill. if a ball mill uses water during grinding, it is a ‘wet’ mill. a typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills.
＊ under the long-term operation, the wet ball mill equipment may have the blockage and leakage situations. so, we should control the material operational throughput well, so that it can simply and effectively prevent the occurrence of blockage; material leakage is caused because the seal layer of wet ball mill inlet has been worn down, we can replace the sealing packing in time.
the ball mill control strategies typically use cyclone dilution water and the number of cyclones operating to control classiﬁcation, and ball mill dilution water to control the ball mill density in order to maintain efﬁcient grinding in the mill. the strategies look at ball mill power and power rate of change and determines if an overload is occurring. concurrently, density in the ball mill is calculated and the ball

the high circulating load means the slurry passes through the mill quickly, preventing the build-up of fines, and is rapidly sent to the cyclones for removal of the fines from the circuit. the result is a ball mill more filled with coarse (+150 mesh size) solids, and containing fewer fine (-150 mesh size) solids, both absorbing the power of the mill.
the mill. this ensures that the balls are covered with a layer of ore solids since dilute slurry increases metal on metal contact between the balls, causing increased wear of the grinding media and reduced grinding efficiency. the ball mill optimizer will use sump water, cyclone underflow water, cyclone pressure and pump

the operating principle of the ball mill consists of following steps. in a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. the material grinding occurs during impact falling grinding balls and abrasion the particles between the balls.
the cyclone achieves 110 microns in stream 19 but only 9 cyclones have been predicted. as an equal number of cyclones are required for 2 ball mills it will be necessary to change the il . set the il variable in the ball mill to 19.5 and calculate. still only 9 cyclones predicted so set the il variable in the ball mill to 19.25 and calculate.
