  • Improved flow- and pressure model for cone crushers
  • 2004
  • Ingår i: Minerals Engineering. ; 17:11-12, s. 1217-1225
  • Tidskriftsartikel (refereegranskat)abstract
    • Cone crushers are used in the aggregates and mining industries to crush rock material. A model was previously developed to predict the worn geometry of a cone crusher. In that model there was some disagreement between predicted and measured geometry. A suggested explanation for the discrepancy is that the flow model used is not accurate enough to predict the pressure and wear on the liners. In this study an alternative flow model is presented that is better adapted for pressure and wear prediction. In the new model, the same mode of motion as in the old model is assumed to occur but only below the choke level of the crusher. Above the choke level it is assumed that downward flow is stopped by other particles that are squeezed further down. To determine the size distribution and bulk density above the choke level, an iterative process was necessary. Simulation results show that the new flow model has improved the accuracy in the prediction of operating parameters of the rock crusher, such as hydraulic pressure, power draw, and close side setting, CSS. There is also some improvement of the prediction of worn geometry as compared to the old model.

  • Influence of particle size on wear rate in compressive crushing
  • 2006
  • Ingår i: Minerals Engineering. - : Elsevier BV. - 0892-6875. ; 19:13, s. 1328-1335
  • Tidskriftsartikel (refereegranskat)abstract
    • The influence of particle size on wear rate in compressive crushing of rock was investigated experimentally. A test apparatus was developed to replicate the squeezing wear that is present in many rock crushers. Silica sand of different size classes between 0.725 and 2.03 mm was used. The crushing load was varied. The results show a strong relationship between particle size and wear rate. The wear rate increases as particle size increases. Not only mean particle size, but also size distribution width also has an influence on wear rate. From some theoretical considerations, an alternative wear model was derived, that matches experimental data well. In the new model, the wear is proportional to particle size and to the square root of the pressure. © 2005 Elsevier Ltd. All rights reserved.

  • INTERFEROMETRIC OBSERVATIONS OF HCN AND CN TOWARDS CARBON STARS
  • 1995
  • Ingår i: ASTROPHYSICS AND SPACE SCIENCE. - : KLUWER ACADEMIC PUBL. ; , s. 501-502
  • Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
    • Using the IRAM interferometer we have observed four carbon stars (U Cam, CIT6, Y CVn, IRC+40540) in the HCN(J = 1 --> 0) and CN(N = 1 --> 0) lines. Here we present some results for CIT6 and U Cam.

  • Klasskamrater revisited : Om klass i ett diskursteoretiskt perspektiv
  • 2012
  • Ingår i: Kulturella perspektiv - Svensk etnologisk tidskrift. - 1102-7908. ; :3-4, s. 15-24
  • Tidskriftsartikel (refereegranskat)abstract
    • My thesis "Classmates" was published 1987 and was a late contribution to a theory/political debate that was about to lose its place in the academy. When the Wall fell in 1989 and the neoliberal transformation of Eastern Europe gained momentum had the terms "class" and "class struggle" become obsolete in a world that celebrated the victory of the market economy. However, as many researchers have pointed out, class is still a reality. Class should therefore regain its place in the critical analysis. New social critical -isms; were formulated in the wake of neoliberalism's global march forward, including a post-Marxism. Prominent in the genre's are the discourse theorists Ernesto Laclau and Chantal Mouffe. In this article it is asserted that the concept of class in the contemporary social context must be used in line with Laclau and Mouffe theoretical/political achievements. It discusses the possibility to use the concept of class within a discourse theoretical framework. As a tool I use empirical data from "Classmates". How are perspectives and analysis affected if Marxism is replaced with post-Marxism? Among other things, it is noted that in the theoretical discourse perspective there exists no experience with direct access to reality. Knowledge about the world is always mediated by discourses. What makes an experience to a class experience is the Marxist discourse. It positions workers as "classmates". For the post-Marxist there is no "working class" as an objective component in the capitalist system. The antagonism between labor and capital is thus not enrolled in the system of production. Discourses determine what meaning "sellers of labor" should be given.
