Operating costs vary depending upon the cost of power, wear rate of mill internals, type of fuel ground etc. The operating costs are estimated to be 20% lower than the tube mill, and 50% lower than ball mill. In China, installation of a VRM for coal grinding would entail 10 to 20% more capital investment.

Ammonia, which does not emit CO 2 when burned, is an alternative fuel to reduce emissions from coal-fired power plants. Therefore, under the Net Zero Scenario, ammonia co-firing is introduced at some coal-fired power plants by 2025. As with CCUS, co-firing ammonia can be particularly beneficial in regions where the thermal fleet is young.
