Gdifference Between Ball Mill Rod Mill

ball mills vs rod mills - 911 metallurgist,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..7 differences between ball mill and rod mill - xinhai,the ball mill is commonly divided into grid type ball mill and overflow type ball mill (named by the different discharging structure). the rod mill is divided into overflow type and open type rod mill, whose diameter of hollow shaft is generally larger than that of ball mill with the same specifications..ball mill vs rod mill | how to choose ball mill or rod,in addition, with same specificationthe, the cylinder rotating speed of the rod mill is lower than that of the ball mill. the rod mill usually uses 50-100mm diameter steel rod as grinding medium, while the ball mill uses steel ball as grinding medium..what is the difference between the ball mill and rod mill,the rod mill uses the steel rod with a diameter of 50-100mm as the grinding medium, while the ball mill uses the steel ball most. moreover, the diameter of the hollow shaft neck is.
