A rod mill uses steel rods as the grinding media in tumbling mills is an efficient means to feed ball mills a product finer than could be made in a crusher but coarser than could be made in a ball mill.
Ball mill is mainly used for grinding in mining (metallic minerals and non-metallic minerals), cement, refractories, chemical, power plant, aluminum,building material, glass, ceramic, steel slag and fly ash, ect. It follows more crushing and less grinding principle to save energy. The feed size to ball mill shall be smaller than 25mm, the output size can be adjusted by revising …

The ball mill is the key equipment for crushing the material after it is broken. Ball Mill is widely used in cement, silicate products, new building materials, refractories, fertilizers, black and non-ferrous metal mineral processing and glass ceramics and other production industries, all kinds of ores and other grinding materials for dry or wet-type grinding.
Furthermore, you are able to minimize the feed ball size to achieve higher degree of efficiency of ball grinding, which is exceedingly useful for a large amount of grinding. This type of rod mills normally feeds balls of less than 15 to 30 mm in diameter to produce 80% product size 500 to 1000m. Fig. 3 Overflow Discharge Type (O.F.D. Type) Use

Rods may be used to reduce large size particles in one mill (Rougher) and feed ball charged secondary mill for fine grinding to -1 micron. The Model 624 is the Laboratory Size mill. It is 6 inches in diameter by 24 inches long, with a 1 hp/230- 460 3 ph/50-60 Hz motor.
The effects of mill feed size reduction on wet rod grinding has been studied by Strohl [2]: when the percent passing 13 mm in the mill feed was increased from 84% to 98% in rod grinding, the fineness of ground products increased from 85% to 94% passing 0.5 mm, while there was a 10% increase in mill capacity and a 15% decrease in wear of the rods.
F = Feed size, 80% passing (µm) f(x j) = -(0.295+x j/1000000) In 2011, Morrell discussed the appropriateness of SAG mill transfer size in regards to grinding mill specific energy modelling. It was suggested that since AG/SAG mills are mostly operated in very near 274

RETSCH is the world leading manufacturer of laboratory ball mills and offers the perfect product for each application. The High Energy Ball Mill E max and MM 500 were developed for grinding with the highest energy input. The innovative design of both, the mills and the grinding jars, allows for continuous grinding down to the nano range in the shortest amount of time - with …
A shell length above 6100 mm can not be recommended. As the length to diameter ratio of the mill should be in the range of 1,2-1,5, the biggest rod mill will convert maximum 1500 kW. Rod mills are used for primary grinding of materials with a top size of 20-30 mm (somewhat higher for soft materials).
EF5BM=[ P80+10.3 1.145×P80] ( 3 ) The EF4 formula requires both the rod mill and ball mill work index (rod mill Wi is used to calculate the optimal feed size) and because this is a "single-stage ball mill" calculation, the F80 is actually the rod mill feed size (10,000 µm) from Table 1 and the P80 is the ball mill circuit product. The EF5 factor only applies below 75 µm to ball
Rod Mill Design Calculations. EF1 – Dry Grinding – for the same range of work, dry grinding requires 1.3 times as much power as wet grinding. EF2 – Open Circuit Grinding – when grinding in open circuit ball mills, the amount of extra power required, compared to closed circuit ball milling, is a function of the degree of control required ...
Effects of mill feed size and rod charges on grinding. The effects of mill feed size reduction on wet rod grinding has been studied by Strohl [2]: when the percent passing 13 mm in the mill feed was increased from 84% to 98% in rod grinding, the fineness of ground products increased from 85% to 94% passing 0.5 mm, while there was a 10% increase in mill capacity and a 15% …
The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6. Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of 3000 to 270 mm (–4 to –35 mesh).
ROD MILLS Rod mills are limited in size to 2000 kW because the longest commercial grinding rod available is 6 m long. For this reason rod mills are rarely selected in the present day environment of large AG/SAG mills and large ball mills. However, it is necessary to discuss their operation because a Rod mill
Other uses of rod mills are in coarse grinding of feed to ball mills, preliminary grinding of cement raw material and cement clinkers and coke for sintering. Classification of rod mill 1. Over-flow type ( for wet mill ) Grinding capacity is low but very effective to obtain rather fine particles. Usually, -15 up to 30 mm size are feed and 80% ...

the copper-bearing minerals in the feed is estimated at 0.03–1.5 mm; therefore, it is important to obtain the appropriate characteristics of the grinding products that are loaded to the flotation nodes. In the paper [15], it has been shown that mineralization in some cases even forces the need to obtain feed with a particle size below 0.01 mm.
Ball mill： Ball mills are the most widely used one. Rod mill： The rod mill has the highest efficiency when the feed size is <30mm and the discharge size is about 3mm with uniform particle size and light overcrushing phenomenon. SAG mill: When the weight of the SAG mill is more than 75%, the output is high and the energy consumption is low ...
