A wide range of flow rates, from 750 to 5300 kg/h of coal, at 60-65% solids concentration has been covered, with both single and multiple passes through the mill. Particle size distributions and power consumption have been measured.

We expect global coal demand to fall by about 8% in 2020, the largest drop since World War II, with coal use declining in virtually every sector of every region in the world. In China, coal demand will decline in 2020 by around 5%, despite the gradual recovery since February lockdown. Coal-fired power generation will be hit especially hard, because the power system is crowded by low variable ...

Coal mill is an essential component of a coal-fired power plant that affects the performance, reliability, and downtime of the plant. The availability of the milling system is influenced by poor controls and faults occurring inside the mills. There is a need for automated systems, which can provide early information about the condition of the mill and help operators to take informed decisions.
