The Selection and Design of Mill Liners MillTraj

multi-stream plants, where mill liner design and selection is only tackled on a cost consumables basis. However, the gains to be had through good liner design and selection are just as great as on the large SAG mills. This paper looks at recognising problems in liner design and selection in existing operations, and then at liner selection for new applications. TYPES OF LINERS . Design and

(PDF) Selection and design of mill liners

The appropriate design of liners continues to be an issue on many mills worldwide. Loss of milling capacity especially at liner change, uneven wear lives along the mill, substantial scrap on worn

Semi-autogenous grinding (SAG) mill liner design and

hydrodynamics (SPH), contribute to mill liner design by provid-ing illustrations of charge motion and detailed information on the interaction between liners and mill charge motion and mill power draft (Nordell et al., 2001; Rajamani et al., 2001, 2003; Cleary et al., 2006, 2007; Herbst and Lichter, 2006). Figure 2 illustrates ball-trajectory model outputs superimposed on a simplified DEM model

Underestimating the importance of an optimised liner design in a mill can lead to back-flow and carry-over processes which can ultimately result in high wear, poor liner life and reduced mill throughput. Installing a Bradken Vortex Discharge End and optimised liner design can lead to significant im-provements in mill performance including: • increased hourly mill throughput • increased

Changing sag mill liners type from Hi-Low to Hi-Hi at

Changing sag mill liners type from Hi-Low to Hi-Hi at Sarcheshmeh copper complex based on physical and numerical modeling M helps understand charge motion in SAG mills for the given liner designs and lifters, ball size and rock properties, and mill operating conditions. Based on the success of the 2-D model of the SAG mill, the 3-D model in DEM was developed. These types of models could

A longer lasting mill liner means less downtime for maintenance or new liner installation. A mill liner that occupies less space allows increased volume within the mill and leads to greater grinding capacity and throughput potential. Safer maintenance. 50% lighter and have 50% fewer parts on average when compared to traditional cast steel liners.
