Home designs of 5000tons per hr sag mills

The operating principle of the ball mill consists of following steps. In a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls. Then, discharge of ground material performed ...

Not more than an hour before. This was the best part of hunting, the passing of time. Joe had probably been in this same spit of spruce and pines, hunting, twenty years ago with his father. When solid forms were so faint, it was easy to see into memory. It was a quality of the hour, neither night nor day, that lent every second its weight.


The Bond rod mill grindability test is performed similarly to the ball mill test. The feed sample is stage-crushed to ½" (12.5mm) and the test is run under a circulating load. The test can also be closed with various sieve sizes, but for AG/SAG mill analyses the standard 14-mesh (1.18mm) sieve is typically used. The rod mill work index ...


The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage 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 ...

The SAG mill consists of a center shell and 2 heads, one at each end: the feed head and the discharge head. The shell and the 2 heads consist of three sections. At the centre of the head section a trunnion is bolted. The trunnion supports the mill and the mill rotates on the trunnion. The trunnion rests on pedestals.Coarse ore from the Coarse ...


The additional charge weight due to steel media in an SAG mill must be considered in the mill design, and if an AG mill is to be converted to an SAG mill, modifications may be required. Many circuit configurations are possible, but essentially, AG and SAG mills can be operated as a single-stage primary mill or can be followed by secondary ...

AG mills (or SAG mills with low ball charges) are often used in single-stage grinding applications. Based on their higher throughput and coarser grind relative to AG mills, it is more common for SAG mills to he used as the primary stage of grinding, followed by a second stage of milling. AG/SAG circuits producing a fine grind (particularly ...

Many types of feeders exist for belt conveyors, but the most popular in hard rock mines is the vibrating feeder. The more expensive apron ( pan) feeder is still employed in certain applications, such as handling large lumps. Other types of feeders are rarely employed in underground mines. Even Ross chain feeders have been used, but ...


Once the power level for the primary (SAG) mill has been set, i.e., design tonnes per hour (tph) x design E total kWh/t from the "geo-comminution" sample profile, serious thought can be applied to sizing the required grinding equipment. Space here does not permit a detailed discus-sion of all the associated topics and the reader is referred


The basic design of the SAG mill is an adaptation of the operating mill at Escondida in Chile. At 38 feet in diameter and 20 feet in length with installed power of 18 megawatts, the Lumwana SAG mill is designed to process 2,450 tonnes of ore per hour with an annual rate of 20 million tonnes per annum. Grinding media will be

End and shell liner design in these mills is much the same as for SAG mills. The effect of liner design on performance is equally as important. For instance, in an iron ore operation using 6.4 m (21 ft.) mills, mill throughput was increased by 15 percent and power consumption reduced by 13 percent by liner redesign alone.
