We are still filling parts requests for mills sold over years ago. patterson mills are available in a wide variety of standard sizes and common types of grinding mills include ball mills and rod mills. this includes all rotating mills with heavy grinding media loads. this article focuses on ball and rod mills excluding sag and AG mills. although their concepts are very similar, they are not discussed here. photographs of a glass ended laboratory ball mill show action of ball mass within the mill. the action of other grinding

Ball Mill And Rod Mill Designing

rod mill design calculations when calculating rod mill power for a rod mill-ball mill circuit, do not allow for improvement in the ball mill performance due to receiving rod mill feed. If the rod mill feed is produced with open circuit crushing, apply a 1.2 inefficiency factor to the power calculated for the rod milling stage only.when the mill is rotated without feed or with very fine feed, the rods are in parallel alignment and in contact with one another for their full length. new feed entering at one end of the mill causes the rod charge to spread at that end. this produces a series of wedge shaped slots tapering toward the discharge end. the tumbling and rolling rods expend most of their crushing force on the grinding mills ball mills, sag mills, AG mills & rod mills We refurbish, design and manufacture an extensive range of high-quality mills and mill components to exacting standards, offering you a turnkey service thats backed by two decades of engineering expertise.
