  • Flow of materials in rod mills as compared to ball mills in

    25/1/2012· This is partly due to the bridging action of the rods over the coarse particles avoiding the fine sizes (the grinding kinetics aspect), and partly due to the nature of material flow through the mill with its rod load (the material transport aspect). This article will stress

  • Flow of materials in rod mills as compared to ball mills in

    This article will stress mainly on the nature of material transport within the rod mill. It was found that the presence of rods minimizes the particulate segregation which is caused by differences...

  • Flow of materials in rod mills as compared to ball mills in

    The rod mill product is characterized by its narrow size distribution if it is compared with that of a ball mill operating under the same conditions in open circuit. This is partly due to the bridging action of the rods over the coarse particles avoiding the fine sizes (the grinding kinetics aspect), and partly due to the nature of material flow through the mill with its rod load (the material transport aspect).

  • Grinding control strategy on the conventional milling circuit of

    milling circuit consists of a rod mill followed by a ball mill in series. Crusher product (-9 mm) is fed to the rod mill, and the water is fed in ratio to the ore feed mass. The rod mill discharge is pumped, without any further water addition, to the first ball mill. The ball

  • Raw Material of Monoblock Mill (Wire Rod Mill) Hani Tech

    Rolling speed, disk weight, and billet section are three basic parameters of high-speed wire rod mill (monoblock mill). In continuous wire rod rolling mill (monoblock mill), when the rolling speed of the first stand is not less than 0.1m/s, the maximum cross-section of raw material is determined by the total elongation coefficient after the final product specification and rolling speed are determined.

     EF1 Dry Grinding for the same range of work, 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

  • PROCESS OF ROLLING MILLS

    25/2/2016· If a mill rolls 80 % of the calendar year, that is 365 x 24 x 0.80 = 7008 hours. If the mill rolls 800,000 tons per year, it runs at an average production rate of 114.16 tons/hour.

  • Rod mills, how they function Mine Engineer.Com

    Rod mills are very similar to ball mills, except they use long rods for grinding media. The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio
