  1. 1. Modeling of Vertical Shaft Impact Crushers

    Author : Simon Grunditz; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; DEM; VSI; Energy Modeling; Breakage Modeling;

    Abstract : One of the largest products in most civilized societies is concrete used to build various types of constructions. To create this product, a mixture of cement, chemical binders, and rock aggregates are combined and then poured into molds where it hardens. The sand part of the rock aggregates is either from natural sources or manufactured. READ MORE

  2. 2. Particle generation for geometallurgical process modeling

    Author : Pierre-Henri Koch; Jan Rosenkranz; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geometallurgy; ore texture; texture classification; breakage simulation; process modeling; Mineralteknik; Mineral Processing;

    Abstract : A geometallurgical model is the combination of a spatial model representing an ore deposit and a process model representing the comminution and concentration steps in beneficiation. The process model itself usually consists of several unit models. READ MORE

  3. 3. Dynamic Modeling and Simulation of SAG Mill Circuits with Pebble Crushing

    Author : Haijie Li; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; Dynamic modeling; AG SAG mill; Fundamental modeling method; Data-driven modeling method; Pebble crushing; Cone crusher; Comminution process;

    Abstract : Grinding is one of the most energy-consuming processes in the mining industry. As a critical part of the comminution process, autogenous grinding (AG) or semi-autogenous grinding (SAG) mills are often used for primary grinding. READ MORE

  4. 4. Development of a geometallurgical testing framework for ore grinding and liberation properties

    Author : Abdul-Rahaman Mwanga; Jan Rosenkranz; Hakan Benzer; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Grindability test; mineral texture; breakage properties; mineral liberation; process modeling; geometallurgy; Mineral Processing; Mineralteknik;

    Abstract : Efficient measurement methods for comminution properties are an important prerequisite for testing the variability of an ore deposit within the geometallurgical context. This involves the investigation of effects of mineralogy and mineral texture on the breakage of mineral particles. READ MORE

  5. 5. Optimization of Compressive Crushing

    Author : Elisabeth Lee; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; Cone Crusher; Modeling; Compressive Crushing; Implementation; Optimization;

    Abstract : With almost all infrastructures being dependent on the supply of crushed rock materials,minerals, and ores, it is fair to say that the foundation of modern society is literally built uponthese materials. As society continues to develop and standards of living progressivelyincrease, the subsequent growing demand for crushed rock materials, minerals, and ores willresult in a need for improving the performance and efficiency of rock crushing equipment.
