• Coarse grinding with ball mill Grinding & Classification

    Unfortunate that you bought a ball mill, that is not the correct equipment for such a coarse feed. You should have bought a rod mill instead; ball mills are inefficient with feed above about 10 mm. As bg76 said, your classifier will be used to pull off your product sizes. The only two ways you can control how much grinding is done is by varying

  • Coarse Grinding in a Ball Mill

    Table of ContentsPractical ConsiderationsCostsTheoretical Considerations Rod mills were developed as a logical substitute for the rolls crusher when larger tonnages had to be handled, on a continuous basis. Today, with even larger tonnages to process, the trend is to install larger equipment, automate the plant and develop the highest availability possible, in order to cut costs.

  • How Coarse can Ball Mill Feed be Grinding

    (The crushing plant runs 11 h per day, the mill 24 h/d.) The mill power (and media consumption) is higher and the mill grinding length is a bit longer in the open case. Is there any other side-effects associated with feeding a ball mill with 16 kW-h/tonne feed which is coarser (closed P80 of 13.4 mm vs. open P80 of 15.4 mm i.e.2 mm coarser

  • Factors Affecting Ball Mill Grinding Efficiency

    b) Feed Preparation With more widespread use of coarse ball milling it is increasingly important to present a suitable feed material top-size to the ball mill. Significant inefficiencies are introduced as a result of the need for larger (and, as a result, fewer) grinding balls. Furthermore, as mill performance is related to the complete size distribution of the feed material, all

  • Ball Mills Mineral Processing & Metallurgy

    Ball mills can be used for coarse grinding as described for the rod mill. They will, however, in that application produce more fines and tramp oversize and will in any case necessitate installation of effective classification.

    Functional performance analysis of ball milling has been described previously by Mclvor. “Coarse” versus “fine” or product particle cut-off size is first selected, usually equal to some benchmark passing size of the circuit product (e.g., 80%). The function of the grinding circuit is to generate new product size material (or “fines”) from “coarse” particles in the circuit feed

  • Ball Mills Mineral Processing & Metallurgy

    Cylindrical VS Conical Ball Mills. For coarse grinding the cylindrical grate mill will, as a rule, give a lower consumption of power per ton of ore than a conical mill. The reason for its better performance lies in the low pulp discharge level which reduces overgrinding at the point where it would do most harm—i.e., at the discharge end of

    Unlike the Ball Mill, however, the Rod Mill uses rods instead of balls as the grinding medium. As a result, its uses are different from those with the Ball Mill. In other words, the Rod Mill gives impact on and grinds coarse particles present between each rod, while no fine particles receive impact and are ground. Therefore, the Rod Mill causes no excessive grinding, enabling you to produce
