Ball Mill Rod Mill Material Flow. material in the mill including the media which may be steel balls in a ball mill, or large lumps of ore in an autogenous mill or a mixture in a semiautogenous mill, as well as the slurry that makes up the operating chargeet jt be the fraction of the mill volume that is occupied by the total charge, jb the fraction of the mill volume that.
Continuous movement of the pulp through the rod mass eliminates the possibility of short circuiting any material. The discharge end of the Rod Mill is virtually open and larger in diameter than the feed end, providing a steep gradient of material flow through the mill. This is .
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.
In all ore dressing and milling Operations, including flotation, cyanidation, gravity concentration, and amalgamation, the Working Principle is to crush and grind, often with rob mill ball mills, the ore in order to liberate the minerals. In the chemical and process industries, grinding is an important step in preparing raw materials for subsequent treatment.
Material transport in ball mills Effect of dischargeend . The results of a detailed study on material flow through a gratedischarge (openend) ball mill versus an overflowdischarge (constrictedend) ball mill are presented to emphasize the effect of dischargeend design on mill .

Laboratory Rod Mill Laboratory Rod Grinding Mill Bench. Xmb series rod ball mill is an efficient laboratory grinding equipment for wet grinding of ore or other materials steel balls can be used as grinding medium instead of steel rods in rod grinding operation particle sizes of final product are relatively uniform and ore overgrinding can be ...
Figure shows a flow sheet where the rod mill is in open circuit and the ball mill is in closed circuit with a classifier. This is a normal setup as the primary function of a rod mill is to provide a uniform sized feed to the ball mill. Figure shows that the rod mill product is classified and a more uniform feed size is, therefore, discharged to the ball mill whose primary function is ...
Jan 25, 2012· As mentioned above, the difference in the material flow behavior between the ball mill and the rod mill partially explains the well known difference in the product particle size distribution of ball mills and rod mills. In the case of ball mills, the axial dispersion is higher and the mean residence time is shorter than those in rod mills.

JeanPaul Duroudier, in Size Reduction of Divided Solids, 2016. 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% moisture.
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 metals.
