or SAG mill. Development of ever larger SAG units has helped in the processing of lower grade ores and the simplification of the crushing section - elimination of secondary and tertiary crushing and of the milling section - in terms of the numbers of ball and rod mills used previously. Principle of Operation The mill operates as a wet .

SAG milling extends itself to many applications due to the range of mill sizes available. They can accomplish the same size reduction work as two or three stages of crushing and screening a rod mill and some or all of the work done by a ball mill. SAG mills are also an optimum solution for wet grinding since crushing and screening in these .

Ball Mills are generally used to grind material 14 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. Various classifiers such as screens spiral .

SAG Mill Ball Charge The SAG mill was simulated to require a 10-12 ball charge with a top size of 125mm. During the commissioning phase no balls were required to be added to the SAG mill to achieve the target throughput of 575tph. This allows for great flexibility in
Jul 08 2020 The semi-autogenous mill is of 10.97 m 7.16 m driven by bilateral small gears with an installed power of 2 8 500 kW and power frequency operation. In 2014 the semi-autogenous mill was put into operation with an average operating power of about 15.6 MW a ball filling rate of about 15 and a ball diameter of 150 mm. Due to the high .
The SAG mill was installed with a low ball charge no variable speed and a fine grind was targeted P80 106 m. High circulating loads and difficulty achieving the target grind size were experienced. This type of ore should have been treated in a high ball charge SAG mill with variable speed capability.

Jan 30 2019 However SAG mill power prediction requires additional development. The next step is power prediction by the discrete element methodbased tumbling mill simulations. Since the density of grinding balls and ore particles is considered in this method it is equally applicable to ball mills as well as SAG mills.
