Coal mills can only operate within a range of capacities (t/hr) depending on the design and control system used. Mill operating window Mill operating parameters determine the mill operating window which provides the limits in which a mill best operates, and outside of which constraints are experienced.

Uses of Coal - Industrial and Domestic Uses of Coal

Domestic Use; Generating Electricity. Coal is generally used in thermal power generation which further helps to produce electricity. Powdered coal is burnt at high temperature which further turns water into steam. This steam is used to turn turbines at high speed in a strong magnetic field. After this, electricity is finally generated ...
