Different configurations of SAG, ball and rod mill occur but in general a SAG mill can be considered an intermediate stage in breaking down rock from the crushing plant, and feeding to ball or rod mills for further size reduction. Types of mill Different types of mill are in operation e.g. rod or ball mills, so

benchmarking SAG and AG mills in a large number of plants. One outstanding achievement of this program (commercial development), was the discovery that in the range of 0.4 to 3mm T80, the energy consumed in either a SAG mill or a ball mill to make a size reduction in this range would be equal and could be estimated using Bond equations.

Every idea in the literature review is not yours therefore you should always acknowledge the source. Except it is common knowledge, always remember to acknowledge the source. At least, cite every paragraph. For example, you can say studies conducted by Mill and Shaw in 1830 shows that breast cancer can be hereditary.

Jun 06, 2016 SAG Mill Design and Specification . The Kidston plant was designed to process 7500 tpd fresh ore of average hardness but to optimise profit during the first two years of operation when softer oxide ore will be treated, the process equipment was sized to handle a throughput of up to 14 000 tpd. Some of the equipment, therefore, will become ...

The primary ball/SAG mill discharge is one of the most severe duties in mineral processing. The suction wearplate is subjected to rapid wear due to high solids concentration and the coarse nature of the slurry. Goulds developed a proprietary process to locate and mold ceramic rods into the rubber liner for the optimum combination of hardness

Nov 26, 2020 The numerical calculation method is used to analyze the wear of the liner of the general structure of a semi-autogenous mill in the axial direction, and the non-uniform wear of each area of the liner is studied to explore the reasons for said wear. The liner is divided into areas along the axial direction, and the discrete element method (DEM) is used to analyze the
