crushing slag and matter

Crushing Slag And Matter In Spain Republic

2014-9-13  Crushing of the ore. Dressing or concentration of the ore. Reduction of metal. ... The ores even after concentration contain some earthy matter called gangue which is heated combine with this earthy matter to form an easily fusible material. Such a substance is known as flux and the fusible material formed during reduction process is called slag.

Fractal crushing of solid particles SpringerLink

2016-6-30  A total of 500 single slag particle crushing tests are carried out for natural slag particles of 2 to 35 mm in diameter. The agreement between the experimental and the theoretical results of the slag particles seems to be satisfactory. The method introduced in this paper not only apply to slag particles, but also any other fractal particles.
