"China's steel mill margins in Aprilwere also the highest since 2018," CBA said. "That's noteworthy because margins are facing the twin pressures of high iron ore and coking coal prices." "China is paying more than double the price for imported coking coal given China's unofficial ban on Australian coking coal."

Milling is the process of machining using rotary cutters to remove material by advancing a cutter into a workpiece.This may be done varying direction on one or several axes, cutter head speed, and pressure. Milling covers a wide variety of different operations and machines, on scales from small individual parts to large, heavy-duty gang milling operations.

Coal mill employed at coal fired power plant. In coal fired energy plant, coal mill is employed to grind, pulverize and dry coal ahead of the coal is transmitted the boiler. The coal is feed into the coal mill by way of a inlet pipe so that the roller coal mill such as Raymond mill and vertical mill can pulverize the coal into particles.
