The principal function of the grate is to retain the ball charge in the mill, while permitting a peripheral discharge. The efficiency of the classifier, when a ball-mill is run in closed circuit, directly affects both tonnage and fineness. This will be discussed under capacity. Conditions Affecting Ball-Mill Capacity

pending a solution to the mill-discharge problem. The only satis-factory way out seemed to lie in peripheral discharge, where centri-fugal force, instead ofopposing the force of gravity in drawing pulp along the lifter arms towards the milloutlet trunnion, would, infact, assist this force over alarge area ofthemilldischarge end.

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. Various classifiers, such as screens, spiral classifiers, cyclones and air classifiers are used for classifying the discharge from ball mills.

A rod mill differs from a ball mill in that the comparatively rigid grinding media operate in a relatively fixed path and reduction results fram line rather than point contact between grinding surfaces. Conventional rod mills are either high or law discharge. In the high discharge mill, the discharge trunnion. is. the same size or only slightly

Rod Mills, How Do They Work? Of the three main types of rod mill, overflow, end peripheral discharge, and center peripheral discharge only the overflow mill is in common usage. For an equivalent grind, a rod mill uses less steel than a ball mill because of the lower speed and better contact between the media and ore.

The mill was loaded with 26.3 kg of 5-mm steel balls, corresponding to 60% of the mill volume filled by a ball bed. A steady-state condition was established by feeding the sand at a given feed rate until the solid discharge rate attained the same value as the feed rate and the size distribution of the product did not change with time.

The rod mills, which have a discharge port in one end of the shell, are called "End Peripheral Discharge Type" (E.P.D. type as per Fig.1), while those having a discharge port in the center of the shell are called "Center Peripheral Discharge Type" (C.P.D. type as per Fig. 2).

end peripheral discharge rod mill for sale. Osborn supplies the three most common rod mill types: overflow, end peripheral and center peripheral Lattice-type ball mill discharge-side security features in

Most discharge via trunnion-overflow; Volumetric loading is similar to that of a ball mill (30-35%) Design standards for drive components are more demanding than ball mills; Dry applications feature a peripheral discharge or an air-swept arrangement; Typical operating speeds are slower than either SAG or ball mills: 65-70% TCS (wet) and 62-63%

Peripheral and trunnion discharge For cylindrical mills which are continuously fed, the discharge of the ground product can be either through the periphery of the mill (peripheral discharge) or through the far end of the mill (trunnion discharge). Ball mills. Ball mill (Fig 1) is same kind of mill as rod mill, except that it is filled

MRD MRE ball mill . When operating on the open circuit principle, the product fineness and grain size distribution are adjusted via the peripheral material discharge. In case of circuit grinding, these parameters are set with the high efficiency separator. The ground product is discharged from the mill through discharge slots provided

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.

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.

The mill discharge from these mills consists of slurry, which goes to the ball mills for further grinding, and coarse pebbles/rocks, which are crushed and sent back to the mill. To maximize the capacity of these circuits, the general practice is to use grates with pebble ports (reaching 100 mm) instead of normal grate openings to increase the
