the structural characteristics of the pebble mill pebble mill also called fine particles from the mill, as the secondary grinding rod mill and grinding equipment.Pebble mill with a ball mill or rod mill in the structure is very similar, and therefore the existing concentrator ball mill is converted into a pebble mill, the structure without a fundamental change, however, need to increase in order to keep the concentrator of the processing capability of the original, mill capacity or the number of units (due to gravel density than steel ball is much smaller). The pebble mill grating Pai mine; using gravel as the grinding media.K-type cylinder liner rubber liner upgrading.K-type increase with liner than ordinary upgrading liner handling capacity increased by 30%, while electricity consumption decreased by 20%. The pebble mill generally hydraulic tribe converter constitutes a closed circuit grinding operations.Gravel grinding to a pebble mill feed ore and gravel grinding media after rod mill, ball mill, or for a white mill kibble after sewing tablets.Secondary grinding for rod mill feed size of a stall is 0.8-0.2mm; deal row of ore from the mill or ball mill, feed size is usually around 0.30-0.075mm. alicey599 Sometimes with gravel mill for grinding ore crushing product of the maximum particle size of 20 to 10mm.The pebble mill used the media referred gravel referral.Gravel medium size is determined based on the principle of equal quality, the quality of the gravel referral ordinary sodium milling ore medium.That inversely proportional to the density of the the gravel medium size ore.The kibble when, the the gravel medium grain size range of 80 to 250 .Finely ground, such as gravel referrals since the mill towel from the previous paragraph, the grain size range of 25-60mm; gravel by a screening crushed product derived grain size range is a group of 40 80mm divisions gravel referral consumed in large quantities grain size range can be expanded to 30 to 100.Experience has shown that the range of gravel referral should be as narrow as possible grinding effects go.Gravel mediated a method of supplying two: usually screened out from the crushed product,Impact crusher gravel mediated consumed in large quantities, can also be from the group of pulverized product portion screened out; Another way is taken from the year since machine, in a period from the mill the mine discharge plaid board open several gravel-chou, "stone" leads the screening,[Mobile Crusher:http://www.xb-machine.com/Crushing_Machinery/Mobile-Crusher.html] to extract coarse level gravel referral.

The latter get gravel referrals since the mill after the "test",[jaw crusher:http://www.xb-machine.com]stone crusher high hardness, good shape, is ideal gravel referral.Many fars affecting gravel mediated consumption, consumption difference of different situations gravel medium timely processing of iron ore, the gravel medium consumption generally about 2% to 7% of the processing power, processing nonferrous metal ores gravel medium high consumption, the individual up to 20% or more.Gravel grinding process parameters: (1) transfer rate and filling rate: the gravel grinding transfer rate is generally 75% filling rate of 40% to 50%.(2) of gravel grinding concentration.The gravel mill grinding concentration generally 10% lower than the ball mill.China the gravel grinding mill concentration generally solid volume percentage concentration calculated to make the steel balls in the ball mill consumption is minimized, the solid volume percent concentration maintained at about 45% and 50%, and gravel grinding pulp density is generally 35% -45% (equivalent weight percent concentration of 60% to 70%).In addition, the best gravel grinding concentration also depends on the size of the gravel referral and quality.(3) product size.The gravel mill for grinding the most economical, when the fineness of the more detailed requirements the gravel grinding unit of processing power and ball mill, the closer, its superior pieces more remarkable.Such as grinding to 75% -85%-0.074, the gravel grinding than milling 25% to 35%, when the ground to 95%-0.074, only l0% reduction when ground to 90% of a 95%-0.05 , the unit of processing capacity substantially equal.Industrial raw materials of the world countries competing with the gravel mill for fine grinding equipment, it can take advantage of in the period from grinding the the middlings Dan Zisheng gravel as grinding media, made the saving of steel consumption,brick making machine power consumption does not increase the economic effect.
