  • Ball Mill Design/Power Calculation

    The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum chunk size, product size as P80 and maximum and finally the type of circuit open/closed

  • Conversion of Rod mill to Ball mill Grinding

    Rod mill to ball mill can be done, it is the other way that is difficult. The biggest issue will probably be your ball storage and feed system. This is very different from a rod feed system. Also balls are fed on a fairly regular basis such as once a day. The biggest operational issue will be mill speed, and feed rate which need to be determined by testing and adjusted based on performance

  • Project Estimating in 8 Steps Project Management Guide

    When estimating projects, talk about the process you might envision taking on. This will certainly impact how you think about effort and scope. Youd never want to sign on for a project that the team is not invested in. Always be sure to include your team in any discussions related to estimating projects and process. Step 3: Expand your project management skill set . Approach your job as

  • What are the differences between ball mill and rod mill

    Recommendation of ball mill and rod mill Ball mill and rod mill are suitable for different materials 1. Selection by material's hardness Ball mill has a strong adaptation of material, and it is suitable for grinding hard materials, such as slag, iron ore, copper ore, etc. Rod mill is suitable for grinding brittle material, such as rare metals.

  • Ball Mills Mineral Processing Metallurgy

    BallRod Mills, based on 4 liners and capacity varying as 2.6 power of mill diameter, on the 5 size give 20 per cent increased capacity on the 4 size, 25 per cent and on the 3 size, 28 per cent. This fact should be carefully kept in mind when determining the capacity of a Steel Head BallRod Mill, as this unit can carry a greater ball or rod charge and has potentially higher capacity in a given size when the full

  • Ball Mills vs Rod Mills

    The voids (or interstitial space) within a rod load are approximately half those in a ball mill grinding load. Rods in place weigh approximately 400 pounds per cu. ft. and balls in place approximately 300 pounds per cu. ft.. Thus, quantitatively, less material can progress through the voids in the rod mill grinding media than in the ball mill, and the path of the material is more confined. This grinding

  • Ball mill Wikipedia

    A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about
