Rod mills, how they function - Mine Engineer.Com

Rod mills usually require greater operator attention. It is important that the rods stay essentially parallel to one another. If rods become misaligned, grinding action is lost and, more importantly, rod tangles occur. Maximum rod length is limited to about 6.1 m (20 ft). This in turn limits the length, diameter, and capacity of rod mills. The heavier rods acting upon the lifters and liners result in greater wear on the mill liners. Rod mills normally carry 35 to 65% rod

Connecting-rod dynamics of the primary drive in

Connecting-rod designs are proposed (on the basis of highstrength alloys), and the crank of the primary drive is modernized (with splitting of the crank gears). That stabilizes pipe production. Mathieu–Hill equations are used to describe the parametric vibration of the connecting rod in the primary drive of a cold-rolling mill for pipe produ

Why is the Rod mill not suitable for producing ...

When Rod mill operating, it will be lifted to a certain height and then falls back, thus the crushing process is completed by collision with parts like rock block, grinding cylinder and lining plate. This process will make a tremendous noise so that multiple Rod mill equipment work simultaneously will
