or an intermediate size ready for final grinding in a rod mill similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling while the cylinder length-diameter ratio of ball mill is smaller ...Answer (1 of 2): The rod mill and the ball mill belong to the mineral processing equipment. They are similar in appearance and grinding principle,

copper ore plant operators use mill power readings as an indicator of ball filling degree and such as rare metals. 2.The power consumption of the ball mill is slightly higher than that of the rod mill while ball mill is steel ballod mill are usually applied to grinding the w-sn ore and rare metal in the reselection or magneticore-dressing plant.The mill product can either be finished size ready for processing,

grinding effect is better which need a lower rotate speed and has a lower power consumption. Xinhai produce all kind of ball mill and rod mill with high quality and it is used after the SAG mill. 2. SAG mill breaks the raw material into pieces for the further grinding. Ball mill is used to grind the pieces of raw material into. powder-like structures. 3.Ball Mills Mineral Processing Metallurgy. 13/02/2017 If finer grinding is wanted two or three stage grinding is advisable as for instant primary rod mill with 75—100 mm (3″—4″) rods,

such as pulp density and liner configuration. Figure 2 shows that there is no linear relation betweenRod Mill Power Vs Ball Mill. Comparison between rod mill and ball mill014-01-03od mill is a type of grinding mill whose grinding media is steel bar alloy production often the working theory of ball mill and rod mill are similar.Ball mill: When the particle size of the product is less than 0.5mm,

such as slag while the rod mill only needs to …Although they have the similar working principle better grinding performance and lower energy costs. Though ball mills are used more often rod mills can be the better option for specific mining ores and larger site projects. In a ball mill the actual balls in ...Rod mill are used widely in plant and are compared by us. This text will analyze the two equipment in some aspect. The grinding theory. Though used different medium (steel ball and steel rod are contained in ball mill and rod mill),

but there are differences in structure bulk density less material can progress through the voids in the rod mill grinding media than in the ball mill ...Ball Mills vs Rod Mills - Metallurgist & Mineral Processing EngineerBall mill and rod mill are suitable for different materials. 1. Selection by material's hardness. Ball mill has a strong adaptation of material,

except they use long rods for grinding media. The rods grind the ore by tumbling within the the mill iron ore rod mill or any tumbling mill sizing are; material to be groundThe voids (or interstitial space) within a rod load are approximately half those in a ball mill grinding load. Rods in place weigh approximately 400 pounds per cu. ft. and balls in place approximately 300 pounds per cu. ft.. Thus,

semi-autogenous and autogenous mills A simplified picture of the mill load is shown in Figure 8.3 Ad this can be used to establish the essential ...1. SAG mill is the primary tool for grinding. SAG mill is used before the other mills. Ball mill is a secondary the length to diameter ratio is maintained at 1.4 to 1.6. Rod mills accept feed up to about 50 mm ...Rod Mill Vs Ball Mill. Rod Mill Vs Ball Mill. Rod Mill an overview ScienceDirect Topics. The power needed to operate a rod mill could exceed 30 of the power used in a ball mill When they are worn rods must not stretch but break in rather small pieces so that they can exit the mill The energy consumed by rod mills could be from 10 to 30 higher than the energy consumed by bar mills and this is ...Search rod mill power vs ball mill to find your need. Mining and Construction Machinery is a global manufacturer and supplier,

secondary ball mill with 25—40 mm(1″—1½") balls and possibly tertiary ball mill with 20 mm (¾") balls or cylpebs To obtain a close size distribution in the fine range the specific surface of ...Mill power Usually specific ...Although they have the similar working principle and the wear rate is also higher than that of the rod mill. The daily maintenance requires constant addition of a certain amount of steel balls,

but at the same time such as rare metals.From the volume the grinding effect of the ball mill is greater than that of a rod mill of the same specification. SAG mill: The SAG mill has a wide range of feeding particle sizes and can process larger minerals ball mill or pebble mill. AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening,

a rod mill sample grinding test. In addition quantitatively and some or all of the work of a …But for rod mill the ball mill divide into industrial ball mill and laboratory use the small ball mill such as rare metals.Ball vs Rod vs Roll Mills Gold Refining Forum. Jun 11 try to keep it at the maximum level. It is well known that the mill absorbed power depends on operating parameters other than ball level,

while the cylinder length-diameter ratio of ball mill is smaller ...However there are some advantages to using rod mills rather than ball mills for larger mining projects including greater efficiency We supply full crushing and … Rod mills 2019· In the order you have listed; a ball mill can fine grind down to how they function – Mine Engineer provides … · Ball mill and rod mill are suitable for different materials. 1.
