The SAG mill trommel undersize is combined with the ball mills’ discharge and pumped to two parallel packs clusters of twelve 660 mm diameter cyclones The cyclone underflow from each line reports to a ball mill while the cyclone overflow is directed to the flotation circuit The designed ball milling circuit product is 80 passing 150 µm

Ball mill shape factors in the period prior to 1927 averaged 111 for 29 center discharge mills and 101 for 30 peripheral discharge mills With the resumption of new plant construction after the 1930’s depression the Morenci concentrator continued the 11 ratio with its 31 x 31 m 10 x 10 ft mills The ratio was increased progressively from then on reaching 16 and 181 for the

1 Calculation of ball mill capacity The production capacity of the ball mill is determined by the amount of material required to be ground and it must have a certain margin when designing and selecting There are many factors affecting the production capacity of the ball mill in addition to the nature of the material grain size hardness density temperature and humidity the degree of

The three surveys with BM8 were conducted in a concentrator in Western Australia processing gold ore by comminution and CIL carbon in leaching The grinding circuit operated a 515 m × 643 m D × L overflow ball mill with fourteen 038 m hydrocyclones in a closed circuit

In cement plant and power plant ball mills remain in current and widespread use The load parameter inside a ball mill directly impacts the stability of production process the grinding

1 Cast grinding ballCylpeb We produce the cast grinding ball cylpeb in 3 types High Chrome Media Chrom and Low Chrome Alloy It is suitable for dry grinding ball mill used in cement brick making construction material making and mining The size ranged from 10mm to 140mm with high hardness low breakage and good wearresistance

Figure 86 The total volume inside the mill is given by Vm 4 D2 mL 1 2Lc L L 1 DtDm 3 1 DtDm 816 The density of the charge must account for all of the material in the mill including the media which may be steel balls in a ball mill or large lumps of ore in an autogenous mill or a mixture in a semiautogenous mill

The ball mill grind various ores and other materials either wet or dry There are two kinds of ball mill grate type and overfall type due to different ways of discharging material There are many types of grinding media suitable for use in a ball mill including ceramic balls flint pebbles and stainless steel balls

Mill Type Overview Three types of mill design are common The Overflow Discharge mill is best suited for fine grinding to 75 – 106 microns The Diaphram or Grate Discharge mill keeps coarse particles within the mill for additional grinding and typically used for grinds to 150 – 250 microns The CenterPeriphery Discharge mill has feed reporting from both ends and the product discharges

The lack of constraints in ball mill capacity in the published ball mill models may result in unrealistic predictions of mill throughput This paper presents an overfilling indicator for wet overflow discharge ball mills The overfilling indicator is based on the slurry residence time in a given mill and given operational conditions

Introduction Overflow type ball mill is the key equipment for mineral materials secondary grinding after feeding material size ranges from 0mm to 35mm Application It is widely applied in the industries of cement silicate products new building materials refractory materials fertilizer etc Also suitable for nonferrous metals ferrous metals and nonmetal separation

Wet ball mills are generally designed as overflow ball mill and are operated in open or closed grinding circuits Wet ball mill is the key equipment for secondary crushing after the material is crushed In Chinas mineral processing industry the application of wet ball mill is extremely wide mainly used for finished products and raw materials grinding a variety of ores grinding in

Ball mills are used primary for single stage fine grinding regrinding and as the second stage in two stage grinding circuits According to the need of customers ball mill can be either wet or dry designs Ball mills have been designed in standard sizes of the final products between 0074 mm and 04 mm in

milling circuit consists of a rod mill followed by a ball mill in series Crusher product 9 mm is fed to the rod mill and the water is fed in ratio to the ore feed mass The rod mill discharge is pumped without any further water addition to the first ball mill The ball mill discharges to a sump where water is

As such when the product is sticky rod mills are preferred over ball mills Rod mills have an industrial yield that is less than that of a ball mill which explains the fact that balls have a much larger grinding surface than rods The power needed to operate a rod mill could exceed 30 of the power used in a ball mill

Overflow Type Ball Mill The overflow ball mill has relatively simple structurethe advantage of no grate fence high fineness in grinding and less ball loading etc Widely used in the second segment or place of comparably finer product When the motor drive the pinion and the big gear rotating the material will get into the cylinder from the left end through the hollow shaft neck from the
