rod mill design

The following equation is used to determine the power that arod millshould draw. The Bottom Table lists many of the common sizerod millsgiving speed, loading and power data. Therod millmotor power is in horsepower at themillpinion-shaft. For different lengthrod millspower varies directly asrodlength. For difference between new and worn liners increase power draw by 6%, and adjust ...

Rod millsare used in an open circuit between crushing and theball mill. They often operate in wet and where the pulp contains up to 50% solid by mass. This machine is equally very applicable to dry where it could take a feed that has achieved 6% moisture. As such, when the product is sticky,rod millsare preferred overball mills.

Rod Mill Design. York surveyors. Firms that come under RICS regulation are easy to spot as they use the words 'Regulated by RICS' on their letterhead and other communication materials.

Rod millsare very similar to ballmills, except they use longrodsfor grinding media. Therodsgrind the ore by tumbling within the themill, similar to the grinding balls in a ballmill. To prevent the conditions leading torodcharge tangling, the length to diameter ratio is maintained at 1.4 to 1.6.

Rod millshave an industrial yield that is less than that of a ballmill, which explains the fact that balls have a much larger grinding surface thanrods. The power needed to operate arod millcould exceed 30% of the power used in a ballmill. ... In Mineral ProcessingDesignand …

Rodsare placed parallel along the length of therod mill.Rodsare 150mm shorter than themilllength. Breakage occurs more from cascading than cateracting. The product size distribution is narrower than a ballmillbut significantly coarser. Most are overflow discharge type. Length-to-diameter= 1.4 to 2.3.Milllength = 7 meters.Rod Mill...

Jan 03, 2014· Modern wirerod millsare high speedmillscapable of rolling of smaller dimensions at high production rates, while at the same time keeping investments and operating costs at the reasonable levels. As a rule, wirerod millsare designed for an annual output of between 300,000 t and over 800,000 t (two strandmills).

GrindingMill DesignBallMillManufacturer.Rod millsare used for primary grinding of materials with a top size of 20-30 mm (somewhat higher for soft materials). The production of fines is low and consequently arod millis the right machine when a steep particle size distribution curve is desired.

The experienced technologydesignon the specification can promise you a well running situation with less over crushing problem. Good at Wet Grinding. We have supplied numberless of wet grindingrod millsfor customer in coal chemical industry, to deal with the coal and petroleum coke material and prepare for the coal water slurry making.

As an engineer who has experience using FEM for thedesignand assessment of SAG and ballmillfoundations, I know that this approach can be time-consuming, costly and- in some cases- not even a hope of being accurate if you don't have appropriate geotechnical and manufacturer ...

Rod Mills. The principal field ofrod millusage is the preparation of products in the 5 mm—0.4 mm (4 mesh to 35 mesh) range. It may sometimes be recommended also for finer grinding. Within these limits arod millis usually superior to and more efficient than a ballmill.

The basic parameters used in ballmill design(power calculations),rod millor any tumblingmillsizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desiredmilltonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum ‘chunk size’, product size as P80 and maximum and finally the type of circuit open/closed ...

Thedesigncharacteristics of industrialrod millsare similar to ballmills. Mostrod millsused in mineral processing are of the overflow discharge type as illustrated in Figure 7.2a. Centre peripheral (Figure 7.2c) and end peripheral dischargemills(Figure 8.1) are also in use.The feed end is generally fitted with spout feeders, scoop feeders, double scoop feeders or drum feeders.
