  • Rod mills, how they function Mine Engineer.Com

    Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of 3000 to 270 mm (–4 to –35 mesh). Grinding action is by line contact between the rods extending the length of the mill. Rods tumble and spin in roughly parallel alignment simulating a series of roll crushers. This results in preferential grinding of

  • Working principle and application range of rod mill_cement

    However, when the rod mill is used for fine grinding, the grinding granularity is less than 0.5mm, the production capacity of the rod mill is not as large as that of the ball mill of the same specification. Because of its small handling capacity and narrow application range, the rod mill is far less in demand than the ball mill.

    Application of Rod Mill and Ball Mill author:dahua time:2018-12-03 . Rod mill and ball mill are both used to grind ore, and be chosen according to the different ing condition. Generally speaking, different contact mode determines different grinding granularity. Rod mill is applied for coarse grinding for the reason that its media is steel

  • Technical Performance and Application of Ball Mill and Rod

    Technical Performance and Application of Ball Mill and Rod Mill author:dahua1 time:2018-10-10 . Ball mill. It is a low level forced discharge type grinding equipment. The slurry stored in the mill has less pulp, and the fine particles can be discharged in time, so that the possibility of over-grinding is small. At the same time, due to the grid

  • Rod Mill an overview ScienceDirect Topics

    Jean-Paul Duroudier, in Size Reduction of Divided Solids, 2016. 3.7.4 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.

  • Rod Mill Design & Power Draw

    The following equation is used to determine the power that a rod mill should draw. The Bottom Table lists many of the common size rod mills giving speed, loading and power data. The rod mill motor power is in horsepower at the mill pinion-shaft. For different length rod mills power varies directly as rod length. For difference between new and worn liners increase power draw by 6%, and adjust

  • Rod Mill Design Calculations

     EF1 Dry Grinding for the same range of , dry grinding requires 1.3 times as much power as wet grinding. EF2 Open Circuit Grinding when grinding in open circuit ball mills, the amount of extra power required, compared to closed circuit ball milling, is a function of the degree of control required on the product produced. The inefficiency factors for open circuit

  • Development, application and operating results of the

    The use of a rod mill for producing manufactured sand is not a recent application. A Marcy Open End Rod Mill has been operating at the plant of the Sun Sand Company, Thayer, West Virginia, since 1925. In early 1940 an. 8' x 12' rod mill of the open end type was installed at Shasta. Dam, near Redding, California for sand production.

  • Ball Mills vs Rod Mills

    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
