Dry Screening Tests Conducted With a Bivi-tec Screen
2008
Screening trials at two South African collieries, one on a small test unit and one on a full scale installation, for plant staff handling fine, damp coal.
What this report foundFine coal was screened at small apertures while surface moisture stayed below about 5 per cent.

Fine coal was screened at small apertures while surface moisture stayed below about 5 per cent. Above that, fines adhered to the coarser particles and screening became very difficult. The dual vibrating polyurethane mats stopped blinding and clogging, so screening area stayed available, but the screen action still could not dislodge fines from very damp coal.
Flammability, corrosion resistance and environment by V Mhlawakhe.pdf
Laboratory work turning high ash coal fines into moulded building composites, comparing coal tar pitch against a silicone binder, with strength, burning, corrosion and leaching tests. For product developers.
What this report foundAir blowing converted coal tar into a pitch with 11.27% volatile matter and 87.68% fixed carbon, which bound high ash coal fines into structural composites.

Air blowing converted coal tar into a pitch with 11.27% volatile matter and 87.68% fixed carbon, which bound high ash coal fines into structural composites. Compressive strengths ran from 106.58 to 344.71 MPa and flexural strengths from 48.75 to 159.30 MPa. Flammability was low across all composites and corrosion rates stayed below those of some commercial ceramic tiles.
