Ag/sag mills 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 of a ball mill. because of the range of mill sizes available, ag/sag milling can often be accomplished with fewer lines than in a conventional rod mill/ball mill circuit. a diagram of types of ag/sag.Apr 09, ball mills. ball mill (fig 1) is same kind of mill as rod mill, except that it is filled with balls instead of rods. because of balls have greater ratio of surface area than rods they are more suitable for fine grinding. balls are also lighter, so the kinetic energy of a single dropping ball is smaller than a.

Feb 08, although similar in operation, a rod mill is often more effective than a ball mill as it requires lower rotational speeds and less steel to achieve the same results. it is, however, limited to maximum rod and drum lengths of approximately 20 feet (6 meters) and is generally only used for wet grinding.Feed size should generally be -1/8″, for ball mill and -1/2″ for rod mill. they are of a sturdy, rugged design to handle frequent use with hard materials. the batch ball and rod mills require a drive roll to rotate the mills. the batch ball mill should be run between 56 rpm and 70 rpm. the batch rod mill should be run between 47 rpm and 79.
Jean-paul duroudier, in size reduction of divided solids, . 3.7.4 performance. rod mills are used in an open circuit between crushing and the ball mill. they often operate in wet and where the pulp contains up to 50% solid by mass. this machine is equally very applicable to dry where it could take a feed that has achieved 6%.Mar 08, recommendation of ball mill and rod mill ball mill and rod mill are suitable for different materials 1. selection by material's hardness ball mill has a strong adaptation of material, and it is suitable for grinding hard materials, such as slag, iron ore, copper ore, etc. rod mill is suitable for grinding brittle material, such as rare.
May 08, ball mill machine has always been the main grinding equipment in wet cement production. in the early years, the rod mill was first used in cement raw meal grinding, which increased the output of the grinding section by 31%, saved energy by 27%, and reduced the consumption of grinding media by.May 31, the type of mill that is used for grinding ore in a modern concentrator is the wet tumbling mill. these mills may be divided into three types rod mills, ball mills and autogenous mills. in the first type, the rod mill, the ore is introduced into the.
