摘要: Abstract Enormous quantities of coal must be ground as feed to power generation facilities. The energy cost grinding is significant at 5 15 kWh/ton. If grindability could increased by preheating the with waste heat, costs reduced. objective this work was determine how affected preheating. method use population balance models interpret results before and after a heat treatment. Simulation locked cycle tests gave 40% increase in grindability. Approximately saving can expected. By using for treatment, targeted savings would maintained.
