Abstract

Liners in Tumbling mill transfer energy to the mill load and has a significant impact on the load behavior. In order to achieve a Domestic technology of Liner design, a knowledge-based package of Liner design was developed by using of domestic equipment and software packages. At the first stage, a proposed Liner that provides an appropriate load trajectory is obtained by simulation using GMT (grinding media trajectory) software and discrete component method (3D-DEM, KMPCDEM software). In the next stage, after validating by a model mill, the manufacturing drawings of the proposed design are prepared. After the construction and installation of the proposed Liners, the Liners wear is recorded using a special measuring device and after preparing a three-dimensional model of Liners, a new design is proposed. Applying this domestic Liner design technology for AG mill Liners at the Gol-e-Gohar mining and industrial company and increasing the Liner lifter face angle from 7 to 30° while keeping the original lifter height resulted in an overall increase of 17% in the mill throughput. By use of this design package in the Sarcheshmeh copper complex ball and increasing the Liner lifter face angle from 0 to 15° and the lifter height from 18 to 21cm, the amount of particles smaller than 75 microns in ball mill 4 product (with proposed design) compared with ball mill 3 (with current design) increased by 2. 5% and the Liners life of the first half and second half increased by 18% and 20%, respectively.
