    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; component; circular economy; obsolescence; remanufacturing; reuse;

    Sammanfattning : The vision of the “circular economy” provides some guidelines for society to strive towards. In the circular economy, material resources are used and reused and recycled better, if not endlessly. Products are to require less material and deliver more function. LÄS MER

  4. 18. REAL TIME OPTIMIZATION OF ROCK CRUSHERS

    Författare :Erik Hulthén; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; crushing plant; cone crusher; real time optimization; rock crusher;

    Sammanfattning : Cone crushers are used in the mineral, mining, and aggregate industry for fragmentation of rock materials. Cone crusher control systems are widely used for wear compensation and machine protection. These systems ordinarily focus on the crusher and not the crushed products. LÄS MER
