Abstract Comminution processes are one of the most commonly used in food, chemical, cosmetics, pharmaceutical industry as well part recycling activities. Disc or multi-disc mills play and important role comminution biomaterials cause their high effectiveness throughput. One challenges, which technology has been facing for long time, is decreasing energy consumption increasing To achieve this, c...

Samples of active coke, fresh and spent after cleaning flue gases from communal waste incinerators, were investigated. The outer layers of both coke particles were separately removed by comminution in a spouted bed. The samples of both active cokes were analysed by means of densities, mercury porosimetry, and adsorption technique. Remaining cores were examined to determine the degree of consump...

An apparatus is designed and fabricated for conducting experiments concerning fluidized segregation to verify a proposed design concept for a more efficient comminution machine. Previous studies have found that the fines distribute the intended crushing load imposed by the machine on the particle bed; thus, the load that must be applied to crush the larger particles increases. By removing the f...

Rate-dependent efficacy has been extensively documented in shock wave lithotripsy (SWL) stone comminution, with shock waves (SWs) delivered at a low rate producing more efficient fragmentation in comparison to those delivered at high rates. Cavitation is postulated to be the primary source underlying this rate phenomenon. Residual bubble nuclei that persist along the axis of SW propagation can ...

BACKGROUND We analyzed the extent of the comminution in the acetabular weight-bearing area, the clinical and radiographic results, and the complications after a minimum 2-year follow-up of the modified Stoppa approach for the treatment of acetabular fractures, and we attempted to evaluate the efficacy of the operative technique. METHODS All of the 22 patients, who needed the anterior approach...
