From July 2020 - February 2021, samples were air dried, sieved to 2mm, and subsamples ground on a ball-mill. Each sample was analyzed for TOC/N on an Elementar soliTOC EA (n=1440), completed in May 2021. After determining that the soliTOC was unreliable for N% analysis, only TOC was kept from these data.
rate at each screen size is calculated from a torque-mill test as in the example that follows. Torque mill solids load during test: 11.25 kg (24.8 lb) of ball mill feed sample from plant survey. Sample is reconstituted with water to be the same percent solids as the plant ball mill discharge. Mill speed: 35.2 rpm (65 percent of critical speed)
