This study was aimed to optimize the extraction process for Salvia miltiorrhiza Bunge polysaccharide using response surface methodology The results showed that four operating parameters including microwave power, microwave time and the particle size had notable effects on the polysaccharide extraction of Salvia miltiorrhiza Bunge. The effects could be ranked in decreasing order of importance as...

This research is focused on the Phase I SABC milling circuit of the Wushan porphyry copper mine. Improvements to the existing circuit were targeted without any significant alterations to existing equipment or the SABC circuit. JKSimMet simulations were used to test various operating and design conditions to improve the comminution process. Modifications to the SABC comminution circuit included ...

Comminution processes are one of the most common for processing energy materials, e.g. coal, biomass, and post-recycling elements. The hitherto unsolved problem is high consumption machines lack precise descriptions phenomenon comminution in terms relationship between design features mills properties comminuted materials. dynamic development simulation techniques based on advanced models method...

We report our experience with carbon-fibre reinforced plastic (CFRP) plates in the management of 19 problem fractures complicated by either infection, nonunion, comminution or contamination. The combination offers secure fixation without inhibition of callus formation.

dability of limestone in their mixtures. This behavior may be attributed to the Representative samples limestone, ilmenite, and quartz, were dry batch ground separately binary mixtures – ilmenite limestone-quartz different compositions ball mill. The study aimed investigate effect mixture composition on mill product characteristics as reflected each two components. results indicated that quartz...

in this research, the efficiency of the comminution circuit as well as the efficiency of size classification equipment of the concentrator plant 2 of sarcheshmeh copper complex was studied. the comminution circuit of this plant includes one sag mill in a closed circuit with a vibrating screen and one ball mill with a size classification system of hydrocyclone. the goal of this work was to calcu...
