  • Tracer study of mass transport and grinding in a rod mill

    A distributed parameter model that in cludes transport parameters such as convective velocity and dispersion in addition to grinding kinetics parameters seems more appropriate for rod mills Analytical steadystate solutions for this model were used by Herbst et al (1975), Fruhwein (1975), Mika (1975, 1976) and Rogovin (1983)Rod Mill Rod Mill, is a grinding machine similar to a ball mill The obvious difference between the two is the grinding medium Rod mill is named after the medium is a steel rod Scope of application: metallurgy, chemical, glass and other industries, in recent years, also used in the sand making industry for construction sandRod Mill machineForged steel balls; P=s=4548t/m3 cast steel balls P=4346t/m3; rolling steel balls P=6068t/m3; steel segments P=4346t/m3filling ratio of grinding medium, When wet grinding: lattice ball mill pi = 40% – 45%; overflow ball mill phi = 40%; rod mill phi = 35% Dry grinding: When material is mixed between grinding media, the grindingBall Mill Parameter Selection & Calculation Power

  • TECHNICAL NOTES 8 GRINDING R P King

    Mills usually operate in the range 65 82% of critical but values as high as 90% are sometimes used A crucial parameter that defines the performance of a mill is the energy consumption The power supplied to the mill is used primarily to lift the load (medium and charge) Additional power is required to keep the mill rotatingRod Mill Design Calculations EF1 – Dry Grinding – for the same range of work, dry grinding requires 13 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 requiredRod Mill Design Calculations Mineral Processing &the rod mill Dimensional data describing each disc and the associated form grinding wheel was collated into a CNC resident lookup table and cross referenced with a number of key parameters Next the advanced facilities of the Siemens 840D were utilised toFrom manual grinding to automation a major step
