The bulk density of a new or freshly culled (i.e., broken rods removed), graded rod charge is 390 lbs. per cubic foot (5.0 kg/m³) Due to lack of culling and the greater tendency for rods to break as mills increase in size, the estimated bulk density of the rod charge must be reduced accordingly (Rowland, 1982).
Many grinding problems requiring a minimum amount of fines can be solved by the Laboratory Rod Mill which assures a uniform product without overgrinding. It can be used as a batch ball mill or as a …

DOVE Rod Mills are highly efficient grinding mills that use steel rods as media to grind various bulk material. They are designed for dry and wet ore grinding applications, and …
Because of this, the rod mill can effectively reduce 1″ feed size to 10 mesh or finer in open circuit. The voids (or interstitial space) within a rod load are approximately half those in a ball mill grinding load. Rods in place weigh approximately 400 pounds per cu. ft. and balls in place approximately 300 pounds per cu. ft..
MARC manufactures a wide range of laboratory metallurgical ball / rod mills and automated Bond rod / ball mills (with wave liners) to suit most metallurgical laboratory applications. Our range extends from small 6L jar-type mills that are manually positioned on rollers to large 30L size mills.
