ball milling equipment rod mill for gold ore grin. ball mill wikipedia the ball mill is a key piece of equipment for grinding crushed materials, and it is widely used in production lines for powders such as cement, silicates, refractory material, fertilizer, glass ceramics, etc as well as for ore dressing of both ferrous and nonferrous metals
for ball mill, the grinding force of steel ball to ore is less than the impact, because the contact area is small between balls and mineral. thus, the throwing motion of ball can produce a large impact, but it need a high rotate speed and has a higher power consumption. but for rod mill, grinding effect is better which need a lower rotate speed
ball mills vs rod mills. 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.
rod mill is a type of grinding mill whose grinding media is steel bar, while ball mill is steel ball. 1. rod mill are usually applied to grinding the w-sn ore and rare metal in the reselection or magneticore-dressing plant in order to avoid the damage caused by the over crushing. 2. in the two stage grinding process, if it requires grinding the ore from 20-6mm to 1-3mm in the first stage, rod
these terms must not be confused with differential grinding, which has to do with the relative grinding rates of two or more minerals in an ore. rod mills = selective grinding. ball mills = non-selective grinding. large balls and small rods compared. is it better to use a grinding mill with large balls or will small rods?
ball vs rod mill conversion. the correct grinding mill depends so much upon the particular ore being treated and the product desired, that a mill must have maximum flexibility in length, type of grinding medium, type of discharge, and speed. with the ball-rod mill it is possible to build this unit in exact accordance with your requirements, as
