  1. 1. Modeling of Vertical Shaft Impact Crushers

    Författare :Simon Grunditz; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; DEM; VSI; Energy Modeling; Breakage Modeling;

    Sammanfattning : 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. LÄS MER

  3. 2. Particle generation for geometallurgical process modeling

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

    Sammanfattning : 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. LÄS MER

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

    Författare :Haijie Li; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dynamic modeling; AG SAG mill; Fundamental modeling method; Data-driven modeling method; Pebble crushing; Cone crusher; Comminution process;

    Sammanfattning : 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. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

  7. 5. Optimization of Compressive Crushing

    Författare :Elisabeth Lee; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cone Crusher; Modeling; Compressive Crushing; Implementation; Optimization;

    Sammanfattning : 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.
