  • How to Reduce Steel Consumption in Grinding Mills

    The way in which the mill liners tumble the ball charge determines how the balls will grind the ore and the liners themselves wear. Tumbling characteristics of the grinding media is determined by height slope and radius of curvature of the liner surface. Hence the design of liners becomes an important factor in determining liner wear rate.

  • Modification of SAG mill liner shape based on 3-D liner

    The common wear rate determination method is to assume uniform wear profile for a liner and measure the profile at one cross section. But it has been shown that the wear profile of the liner is not uniform (Banisi and Hadizadeh 2006).Thus a new method was proposed and tested which measures the wear profile through building a 3-D model of liners after any given operating time. The dynamic charge behaviour within mills is the key metric for operational diagnostics. As shown in Fig. 2 under relatively stable ore ball water and recycle feed rates overthrow of the charge will cause extensive wear on mill liners whereas reduction in throughput is resulted when underthrow is exhibited.Studies have been conducted to develop on-line measurement solutions for charge

  • Optimization of Cement Grinding Operation in Ball Mills

    Operation and Elements of a Closed Circuit Ball Mill System. Cement ball mills typically have two grinding chambers. The first chamber is filled with larger diameter grinding media and lined with lifting liners. The first chamber coarse-grinds the feed material and prepares it for the second chamber. The second chamber is the fine grinding chamber. In this work it has been attempted to find (possibly) a reasonable relationship between variations in ore characteristics together with liner quality and the amount of wear rate in different liner/lifter segments of a semi-autigenous mill. Liner/lifter segments are supplied
