This paper outlines a mechanical transformation process for rubber recycling, demonstrating the development of new material from used tires. With crumbs obtained using crusher-compactor, novel manufacture O-rings has been developed, with properties close to those found on market. The includes an experimental methodology sulfur vulcanization system choice and quantification ingredients, as well ...

This paper presents the characterization of a secondary cone crusher concave liner made Hadfield steel used in Chilean mining after crushing copper minerals during all service life. During use, suffers indentation (cold working) and abrasion; this combination provides with layer that constantly renews itself, maintaining surface highly resistant to abrasive wear. The results presented here were...

ABSTRAK PT.DAP merupakan perusahaan manufaktur yang memproduksi kertas serta menggunakan boiler dalam proses produksinya, Namun, belum ada penerapan manajemen K3 pada divisi secara optimal. Hal ini menyebabkan terjadinya beberapa kecelakan kerja mengganggu kesehatan pekerja terutama boiler. Pengolahan data penelitian metode HIRARC kemudian hasilnya akan diterapkan lembar job safety analysis (JS...

A method of multi-objective optimization is proposed to improve the quality of crushed materials and vibration performance of the rotor. This method is driven by the first order natural frequency and the radius of the rotor. The Central Composite Design (CCD) experiment method is used to guide the selection of appropriate structure finite element analysis samples in design space. The quadratic ...

PURPOSE Lipid suppression in MR brain imaging and spectroscopy has been a long-standing problem for which various techniques have been developed. Most methods are based on inversion recovery or spatially or spectrally selective excitation of the lipid signal followed by dephasing. All techniques require additional RF pulses, gradient crushers and delays, which increase the duration and complexi...
