Rod mills are very similar to ball mills, except they use long rods for grinding media. 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.
Ball mills designed for long life and minimum maintenance overflow ball mill sizes range from 5 ft. x 8 ft. with 75 HP to 30’ x 41’ . and as much as 30,000 HP. Larger ball mills are available with dual pinion or ring motor drives. Our mills incorporate many of the qualities which have made the Marcy name famous since 1913.
Calculate and Select Ball Mill Ball Size for Optimum Grinding. In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do.
Grind coarse feed material with a reliable Rod Mill that won't over-grind. If you are in need of an application for coarse materials like limestone, potash, coal, phosphate and bauxite, you may be looking for a solutions like Rod Mills. Rod Mills are particularly useful, if you run a low tonnage operation and are looking for coarse product.
Calculate Ball Mill Grinding Capacity As defined this value should never exceed 100 but in some cases – particularly in Grate Discharge Mills – it could be lower than 100 Note that this interstitial slurry does not include the overfilling slurry derived from the difference between the Charge and Ball Mill Filling
The design characteristics of industrial rod mills are similar to ball mills. Most rod mills used in mineral processing are of the overflow discharge type as illustrated in Figure 7.2a. Centre peripheral (Figure 7.2c) and end peripheral discharge mills (Figure 8.1) are also in use.The feed end is generally fitted with spout feeders, scoop feeders, double scoop feeders or drum feeders.
calculation for get it dimension of the components of a ball mill tool that has been planned. In design ball mill was started from determining the volume of the tube
Three types of discharge ends are used, namely mills with wide peripheral discharge, mills having a scoop after the grate to lift the product and mills having the discharge through a trunnion. The feeders are either spout or chute type. Low aspect mills are usually seen with spout feeders, while the high-aspect mills are fitted with chutes.

While there are several types of ball-mill on the market, particular attention will here be given to the diaphragm type (Peripheral Discharge Ball Mills ), as the open-trunnion type, especially the conical mill, has been thoroughly discussed here.
acid-resistant mills for grinding in raffinate or with acid-forming feed, as well as special feed and discharge arrangements and special bearing arrangements. Outotec SAG and ball mill Outotec high-performance grinding mills use advanced simulation tools for the best possible process efficiency, mechanical reliability, and maintainability.

The profile can be better customised to suit mill speed and filling and therefore optimise performance, and it allows more material in the lifter for a given base width, but the mill must only run in one direction. 7.

Marcy mills are recommended to operate a peripheral speeds governed by the following relationship : Peripheral Speed= 108.8 D 0.3 meters/ min. D = mill diameter in meters. The Marcy expression is applicable for mill diameters between 1.52 to 4.1meters. Using peripheral speed, the rotational speed can be determined.
Ball Mill Design Pdf alibaba. ball mill design pdf. Ball Mill are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reduced.
