This means a rod mill equal in capacity to a ball or SAG mill would take up more plant floor area requiring a larger building. Also since SAG (semi-autogenous grinding) uses less media than a comparable rod or even ball mill. ... The pairing mill combination of a SAG/Ball mill is common in copper/gold mines for that reason. This combination can ...

Rod mill is a roller-type grinding device with a long and round metal rod as the roller. In 1870, a rod mill with uniform discharging particle size was developed on the basis of the ball mill. ... When the two-stage grinding process is adopted, if the first stage needs to be ground from 6–20 mm to 1–3 mm, the rod mill is used as the ...
A bar and rod mill, also known as a rolling mill, is a facility used for the production of metal bars and rods through a process called rolling. It is commonly used in the metalworking industry to shape and form metal into various profiles and sizes. The primary function of a bar and rod mill is to reduce the cross-sectional area of a metal ...
Rods in place weigh approximately 400 pounds per cu. ft. and balls in place approximately 300 pounds per cu. ft.. Thus, quantitatively, less material can progress through the voids in the rod mill grinding media than in the ball mill, and the path of the material is more confined. This grinding action restricts the volume of feed which passes ...
Ball mill: When the particle size of the product is less than 0.5mm, the grinding effect of the ball mill is greater than that of a rod mill of the same specification. SAG mill: The SAG mill has a wide range of feeding particle sizes and can process larger minerals, but at the same time, its output particle size is relatively larger.
