In coal milling for power stations, a ‘closed-loop’ process is used in which the rejects from the classifier are returned to the mill for regrinding. in vsms, the re-circulation loop is within the mill, but some mill types would have an external loop. in fact, there are a number of re-circulation loops within a mill system.
Jun 09, 2021 the capacity factor of coal plants — the percentage of power they produce relative to their maximum output — dropped from 62 in 2011 to 40 last year. the lower output means fewer workers, from the mines to the power plants. moody’s investors service forecast in 2019 that coal would be only 11 of electric power generation by 2030.
