Measuring Coal Mill Particle Sizes

As the mesh size increases the particle size decreases to create a finer material Mesh size is not a precise measurement of particle size but it is a fair estimation A micron also called a micrometer is the metric unit of measurement for 0 001 millimeters It is used here to refer to the thickness or diameter of the reduced material
