Mechanochemical technique aims to strike a balance between defect formation via ball milling and size adjustment of a solid grain to nanoscale (<1000 nm) (Ullah et al., 2014).During the process, a highenergy mill is employed and a specific powder charge is placed along with a milling medium (Lin et al., ).The kinetic energy Reduction of sewage sludge by ball mill pretreatment and ,The effects of ball mill pretreatment and Mn catalytic ozonation on the reduction of sewage sludge were investigated. The ball mill pretreatment increased ΔSCOD from 2,000mg/L to 9,000 mg/L, as Total Solids (TS) increased from 1% to 4% at a specific energy of 75.8 KJ/gTSS. The increase in disintegration ratio (DR), which is an index of

Paper mill sludge (PS), produced during paper production, is composed of mineral fillers, small cellulose fibres, water and organic compounds. The results show that when the ball milling time increases, the particle size of fly ash decreases and the distribution becomes narrow.
