• 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

    Metallurgical ContentOpen Circuit GrindingClosed Circuit GrindingGrinding Circuit Process Control VariablesGrinding Operating Costs The simplest grinding circuit consists of a ball or rod mill in closed circuit with a classifier; the flow sheet is shown in Fig. 25 and the actual layout in Fig. 9. This single-stage circuit is chiefly employed for coarse grinding when a product finer than 65

  • 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 Mill saVRee

    If rods are used instead of steel balls, the mill is referred to as a ‘rod mill’. Closed-Circuit or Open-Circuit. Ball mills may operate in a closed-circuit, or open-circuit. Closed circuits return a certain amount of the ball mill’s output back to the ball mill for further size reduction.

    AG/SAG mills can accomplish the same size reduction as two or three stages of crushing and screening, a rod mill, and some or all of the of a ball mill. Because of the range of mill sizes availe, AG/SAG milling can often be accomplished with fewer lines than in a conventional rod mill/ball mill circuit. A diagram of types of AG/SAG

    The larger the diameter is, the slower the rotation will be. Ball Mills are generally used to grind material ¼" and finer, down to the particle size of 20 75 microns. To achieve reasonable efficiency, the ball mills are to be operated in a closed system, with oversize particles continuously being re-circulated back to the mill and to be reduced.
