Damage of abrasives (e.g. garnet abrasive) represents a current problem in the AWJ technology. Due to this, possible reuse of the garnet recyclated from sludge after the cutting by the AWJ technology is investigated. Geological origin and material properties of almandine garnets (mineralogy, granularity, grain shape and others) influence this technology significantly. New parameters of input materials, such as the specific surface area and pore distribution (criterion of the internal grain damage), are examined by the N2 adsorption method for the evaluation of damage of abrasives. |
